How to add or refill your Trim and tilt fluid on an outboard.

The following video shows the steps to add hydraulic fluid or trim and tilt fluid to your trim and tilt. It is a step by step video that will hopefully make this process a little easier to understand, and perform.

[@daveseeley]

Thank you bro! As simple as it seems, I like the security of seeing someone else (you!) do it first. Well done my friend, well done.

[@gregbellinger5765]

Great job on the video. I've used the video 5 times because I forget from year to year. Really good camera angle. I had to replace the screw for my Force 120 because it's place, but I keep it as a backup to the new one in case I lose the new one.

[@glksr51]

that was a very educational video I'm so thankful for you for taking the time to show people like me how to service our tilt and trim motor I thank you

[@kedricknicholas5573]

Great tutorial...gave me the confidence I needed to do this myself. No more trips to the mechanic for such a simple task!

[@HoustonR6ryda]

I want to thank you for this ,it got me back on the water. I went and bought a big stout flathead and fluid $15 later I'm good.

[@BackwoodsGourmetChannel]

My 70HP got stuck today while on Tampa Bay. Had to idle 7 mile back to the ramp because it was trimmed halfway. It' been cavitating since I got the boat. Defiantly gonna try this. Thanks for posting.

[@hansg6336]

I have an older (1982 140 Evinrude outboard) so this was perfect. However, if you're losing hydraulic fluid, it probably means a seal in the system is cracked and is leaking. Adding more fluid means it will continue to leak to one degree or another unless seals are replaced. Until then, the tilt trim function might fail on the water. Most power trim outboards have a manual by-pass so you can raise or lower the motor if the power function fails on the water. Check your manual.

[@timmysparky8145]

Great video. Have to add fluid to my johnson 150 but it is down. Was watching your vid on how to add fluid and then saw this! Thanks a million reeltease😎

[@gregbellinger5765]

I use this technique every season on my 1987 Force 125 and it works extremely well.

[@glenntavalozzi5176]

well time to do my bass boat👍

[@billblack432]

This guy is on it. I had a bouncing problem when lowering my motor. Tried many things to correct it, none worked. Followed his method and WOW, cured my bounce problem. Thanks buddy!

[@ReelTeaseFishing]

Glad it worked for you!! Take care Bill

[@coledaddy818]

Mine has the rough sound when I enter the trim stage. Lots of air still in it on the way up. But not when going down or tilting up.

[@ReelTeaseFishing]

@@coledaddy818 level off the trim and tilt by lowering the tongue jack on the trailer to get the trim as level as possible. Then tilt the engine up & lock it. Unscrew the cap and give it an hour or two uncapped to allow the air to rise out. Micro bubbles take a while to flow through the oil and escape. Top off. Cap it and cycle up and down a few times. Repeat the process another two times. Should solve that

All right Man - good stuff !!

[@ReelTeaseFishing]

any power trim and tilt oil will work. You can find it at any of the local bait and tackles or big chain stores such as west marine, bass pro, walmart etc.

[@ReelTeaseFishing]

yearly checks on the oil and to check for water in the oil ( milky colored oil) and when not used or stored running the trim up and down a few times maybe 1 or twice a month to keep it from freezing up. other than that rinse with fresh water after every outing. you can always coat the trim and tilt (Metal housing) with some type of spray on grease or silicone to protect it from rust every so often.

Awsome..thanks

[@serenday]

Great story Reel. The Q/A answered most of any more questions and I am now a certified tilt/trim oil level mechanic! One question I didn't see: If your your motor 'bleeds down' overnight, is the pump needing work? (Mercury. New manual release valve and o-rings.)

[@ReelTeaseFishing]

What do you mean by bleeds down over night? Do you mean the engine gradually falls or lowers overtime? Or do you mean fluid is coming out of the pump overtime?

[@serenday]

ReelTeaseFishing Yes, motor sinks down from raised position. No oil leaking out though.

[@ReelTeaseFishing]

Hey Glyn, if you dont see oil leaking that is a good sign. First make sure the Manual release screw located on the right side of the T&T unit is tight. If it was loose this might be why it was lowering over time. Heres a video explaining where that manual release screw is located kzbin.info/www/bejne/pojMdmaXZ9uIotk However, If it was tight, I would then raise the engine to the highest point and engage the engine lock so it stays in the up position. Then remove the fill screw, usually found on the right canister near the middle or top end. Once removed add fluid until it is completely full. (If the boat is on trailer, make sure to lower or raise the tongue (Front End) so the boat sits perfectly level) By positioning the boat level the fluid in the trim and tilt will also be level allowing the most fluid into your T&T. Once filled, cap it and lower then engine and raise it a few times. then go ahead and raise the engine and engage the lock, remove the fill screw one more time and inspect to see if you need more fluid. If the fluid looks bubbly or you noticed air pressure when you removed the screw, leave it standing without the screw for 15 minutes to allow any air trapped in the fluid to escape. then fill cap and should be done. Hope it all makes sense.

[@serenday]

ReelTeaseFishing Yes it all makes sense. The motor is a 1986 Merc 90 so it has a reservoir on the left side with a fill tube down to the reservoir. The tube has a screw cap on the top. I've been filling the unit to the cap. When i run the motor in the fast section of its raise/lower it works fine but when it goes to the lowest position and then back up you can hear a 'rushing' sound like fluid being sucked in someplace. After stopping at the top and removing the cap you can see air bubbles. I'm leaving it locked up overnight with the cap off and will try tomorrow. The manual relief valve is tight and was just replace including new o-rings. No external leaks.

[@serenday]

Glyn Thorman I filled it and let it sit overnight. No bubbles in morning so topped off and put cap on tight. Raised up and by next morning its was down. (Dropped 10" in 1.5 hrs within tilt position.) I think the pump is bleeding into the reservoir. What do you think?

[@tracymarino2555]

Great video, is there any other maintenance that is done to the tilt and trim system? Thank you.

[@ReelTeaseFishing]

Thank you :)

[@ReelTeaseFishing]

Mr. TXMAN, although you may be following the manual. That does not mean it is the ONLY way. In fact, the method that I am describing is actually a more time efficient way to fill your trim tilt. By not putting back the fill screw you will allow any trapped air to immediately escape. Thus if you put the fill screw back on, the air will get trapped and mix into the oil, then you will have to wait for the air to separate and escape taking a few hours. Although my method is messy, it works better.

[@81mrlz]

I use normal car automatic transmission oil. have never had problems, of course when people do not know mechanics hydraulics or electronics they buy what the sellers want them to buy only to waste their money, to add car generator works just as well on a boat 11 years still works

[@ReelTeaseFishing]

Yes ATF works just as good. Many with new engines, use the authorized fluid to not void warranty.

[@christophermoore5190]

Thanks! Very helpful 👌

[@ReelTeaseFishing]

Glad it helped 👍🏽

[@351kostakis]

Fantastic

[@bassaholic713]

i have to say, following your steps is a lot more difficult since each time lowing the motor down, the oil would spits out a lot. it makes it harder for the trim to come back up unless you add more oil into it. I went back to the manual book and doing it with the fill plug on and each time the motor is raised up, i would slowly unscrewed the plug and let the air come out. And then I would add fluid little by little. That works fine for me.

[@24elkbass]

I agree. When motor is coming back up.....it's spitting out fluid. Ugh. I'll try with cap on.

[@jerryencinias6411]

Help, my trim motor works going down but only rises 1".

[@TailTaleOutdoors]

You did it correctly lol

[@russellcrawford4809]

my Evinrude service manual says to put the screw back in only a couple threads while moving it. That way it bleeds out more air and less oil

[@ivorygreen3503]

on the power trim it is leaking oil what can we do and do u have a video on how to do it. How much do it cost to have this done or is it something that can be done yourself they told my husband it would cost 1200 dollars to fix it. Please tell us an easy way we need the motor when we lift it leaks

[@RicFlair3333]

Great video buddy. Would the Mercury T&T be about the same thing?

[@ReelTeaseFishing]

You wont be able to fill it up if its in the down position because you wont be able to reach the fill screw. Your problem may not be fluid though since usually you will see the problem when the engine does not come down, or it falls slowly. If its stuck and wont go up, I'd say check the relays. there are two relays. One for up and one for down. Also do your hear any noise from the trim and tilt? Maybe low on battery? lastly I'd remove the pin connecting the engine to the main shaft and lift it.

[@GenericUserUnknown]

Thanks for taking the time to make this video. I'm curious about CHANGING the fluid too. Do you know of a DIY how-to video for that? Either way, thanks!

[@ReelTeaseFishing]

If you want to change the fluid then I would suggest removing the screw that is near the bottom of one of the cylinders. once you remove that screw along with the fill screw it should all pour out. In all honesty I don't think you should empty it unless your fluid looks milky. emptying it can become more of a pain if it isn't necessary. Good Luck

[@ReelTeaseFishing]

hey bud, hope you figured how to do this by now. its quite simple as you will need to remove both screws located on your lower unit. first remove the bottom screw, then slowly remove the upper screw to allow the entire unit to empty. Makes sure to collect the oil and dump it appropriatly. Next you will attach a pump to your lower unit oil bottle and start pumping oil through the bottom screw until it start to come out the top screw. once it begins to leak out the top screw go ahead and tighten that top screw back on. next pump one or two more pumps of oil and remove the pump from the lower screw fitting. then quickly screw back the lower screw back on. (when removing the pump to put back on the screw has to be quick to minimize the amount of fluid lost. Sometimes turning your engine so the screws are facing up lifting your engine will make this step easier.) and your done. wipe down and make sure fluid isn't leaking from around the screws

[@nickvergin]

Thanks

[@timthompson3755]

my trim motor has been real sluggish last cpl months...have to tap it with a hammer to wake it up sometimes..well it finally stopped all together. I figured out i had to take the release valve with o rings out to release pressure to manually raise motor!( Is there an easier way?) So now my fluid is drained, Should motor still work? Do you think motor is done...will putting more fluid in it help motor kick on?

[@ReelTeaseFishing]

I'm not 100% sure, but I do believe they are pretty much the same. They work pretty much the same way. The screws might be located in a different spot though.

[@billpontoon4498]

Do you have a video or know of one that shows replacing seals around cylinders. I have a 90 etec that is leaking the trim fluid around the cylinder. There is only one cylinder for this.

[@pukaman2000]

It could be that you need a rebuild. Water probably got into the electrical area and did some damage to the brushes. Try checking the oil to make sure it is not white and try tapping the motor to see if it will work.

[@5703bl]

Hello I have the same motor my tilt(middle one) have a little seal leak. How do I remove the tilt rod to put new cap and seal on. Thanks

[@joshpack7642]

I have a 95 legend with 96 mercury 115. I can trim all the way up and watch it slowly leak down until it bottoms out.. Will the fluid fix my problem or is it something else? Thanks.

[@worldwidefishingguide]

Thanks ReelTeaseFishing

[@7046463]

YO BRO great gd video. what fluid must i use. powersteering fluid? can i use amsoil power steering fluid i heard it's vry good.

[@gilbertorodriguez2534]

While I'm driving my boat the motor starts to lower it self on its own. If I do this will it stop that?

[@ReelTeaseFishing]

after that, uncap it and allow it to stand about 15 more minutes to allow any air or air bubbles in the oil to escape. fill to top and screw back on.

[@ReelTeaseFishing]

Every time you lower the engine, you will lose oil. make sure that if the boat is on a trailer, the trailer jack is set to the lowest possible or that the trim and tilt is sitting even. You don't want the boat sitting to high in the front, thus it will never allow you to fully fill your trim and tilt. Also if you cant get all the air out let it sit in the upward position with the screw cap off for about 30 min. then fill her up. cap it. lower it and allow it to stand another 30min.

[@wazup3333]

i have a 2000 mercury and cant get it to work, i feel like it has air, it randomly will move the motor for a second but rarely.. i tried every method lowering it with screw cap off but fluid just will come out, tried manually lowering with force with manual release unscrewed and the fluid is topped off. There was no oil residue anywhere so it doesnt look like an air leak

[@ReelTeaseFishing]

@@wazup3333 Make sure the screw ( manual relief screw) on the trim and tilt is not loose. It is usually located on the lower right hand side of the trim and tilt housing. I have a video called "how to manually lift and lower your outboard" that shows that screw location. If that is nice and tight. I would suggest you raise your engine to the highest possible point.Then try to fill it to the max. leave uncapped wait 15 minutes the refill it again. then cap it and see if it will start moving. If that doesn't work try manually raising and lowering the engine a few times by hand. this allows air to be purge out of the system. then uncap and try to refill to the max. Lastly you may have a motor that has gone bad. Although usually they just ground out sometimes they burn out and just don't engage anymore.

[@nsdonmck3219]

2008 Etec 135 on a buddy's boat, once and a while the trim will go back up while cruising, all by itself. It will trim back down and work fine again, it goes all the way up and down as well. Haven't checked fluid level yet, but is that possibly the problem?

[@tonyxiong7640]

I am having problems with, took the other day out and some how the Tilt was stuck all the way up, wouldn't go d own. Thought it was low on fluids and when I decided to add fluids to it, some how it was able to move up and down. Right when it went down its stuck and I don't know whats wrong with. Any suggestions? Maybe I might of let to much air in it?

[@txman201]

OMC Power Tilt/Trim & Power Steering Fluid, or Dexron II automatic transmission fluid.

[@ReelTeaseFishing]

The trim and tilt is two systems. the first is the trim, it has two pistons that raise your engine only slightly, then the tilt which is made to raise it completely for transport. the engine when under a load will not stay in the tilt position, it will lower to the trim where it should stay unless you trim it any lower. the engine after a certain RPM will usually not allow you to raise it. basically your engine will/should not run on the tilt shaft only as it cannot hold the load.

[@ReelTeaseFishing]

If this is the case because you powerload your boat onto your trailer, this is normal. The trim and tilt is two systems. the first is the trim, it has two pistons that raise your engine only slightly, then the tilt which is made to raise it completely for transport. the engine when under a load will not stay in the tilt position, it will lower to the trim where it should stay unless you trim it any lower. read comment above as it might help you as well. but seems like its normal.

[@shammond82]

Nice video. I am in the middle of replacement my power trim electric motor and I noticed the fluid is milky. I am guessing water has gotten into it over time so I am going to drain all the fluid and replace. Any tips you can give me?

[@ReelTeaseFishing]

Yes drain the fluid but before refilling replace all the gaskets and orings around the shafts and the fill screw. This is most likely how water got int.

[@niprjct]

Hi am new to boating, my tilt trim stopped working, i saw some fluid on my floor when i got back from the lake. What kind of fluid should i buy? You seem to have in a tube all i can find online is like penzoil type of oil. very appreciated JD.

[@ReelTeaseFishing]

Hey, thanks for watching. Really any trim and tilt fluid will work, some people even use ATF without any problems. I purchased that tube at Walmart, since I wasn't going to use an entire bottle I figured the tube will make applying the oil, an easier job since it's half that of the regular quart size bottles. You can also buy a small funnel/tube applicator that will screw into the quart sized bottles at any auto parts to make it easier to pour into the reservoir.

[@rayjay6361]

ReelTeaseFishing Actually I got it absolutely level, But it was a pain in the butt ( although completely worth it ) I had to loosen the mounting bolts (4) 3/4 bolts almost all the way out then manually lift/tilt the engine until my magnet level said it was good then wedged it in place with 2x4's and scabs, The fluid looked like frothy milk, I doubt it had ever been serviced . I did run into a situation though that I would like to address , when I got it emptied ( filling and running it up and down as the video states ) all of the sudden it wouldn't lift , The cure was sticking and holding the tube tight against the fill hole , then squeezing and pressing the up button at the same time until it was fully extended. Anyhow, Job done : ) and my tilt is holding tight where as before I would trim going down the lake only to watch it lose its trim slowly. These videos are real money savers, keep up the good work guys : )

[@Mjp74]

thumbs up!

[@mustafapanahi3081]

tnx for this video , i just want to know why the trim and tilt is not going up and down completely ??? works something like to half and then stop when i change the fluid... it is yamaha 40 hk ,

[@ReelTeaseFishing]

you do not have enough fluid in the trim and tilt, or there is air in the system. Perhaps you need to remove the fill screw and allow any trapped air to escape and fill the reservoir to the top.

[@ReelTeaseFishing]

if it goes up but very slow or rough it may be because of the oil. drain the oil and refill using the method above. Too little oil and it wont be able to lift the engine properly. (which sounds like your problem)

[@ReelTeaseFishing]

I think its your down relay. The relay switches go bad and this is mainly what happens. if you dont hear the trim and tilt running then its most likely that.

[@zeauz]

nice skeg :D

[@rayjay6361]

I'm changing the T&T fluid on my 93 60hp Merc , It's mounted on a pontoon boat and no matter how far I drop the nose the T&T mechanism will not sit level , Any suggestions on how to get it level ?

[@ReelTeaseFishing]

Hey thanks for watching, if there is no way to completely get it level try putting a brick or 2x4 under each tire and then slowly drivin the trailer onto them. This should raise the back end up about 2 inches, hopefully you can now get the tongue low enough to level your T&T. If that doesn't work out, try over filling the reservoir a it and then quickly get the cap screwed in. Kind of how it would be done on a lower unit oil change.

[@ReelTeaseFishing]

@zeauz Florida bay & especially Flamingo will do that to ya. :D

[@CndDFilms]

I have a Johnson 150vro trim and tilt works good. But when I get on the water. Trim will not hold. what. can be wrong

[@anthonyhill3771]

What is he using to add in the screw? Hydraulic fluid?

[@alyssablake100]

hi I have the same problem as the one below trims up and down fine but when I take off the engine slides down and I cant trim up.but when I stop it trims up fine.is it maybe low on oil?

[@ReelTeaseFishing]

seems like their is air in the system. lower it using the manual release screw on the bottom side of the T&T

[@wazup3333]

how does air escape when using the manual release?

[@ReelTeaseFishing]

@@wazup3333 the manual release does not allow air in the system. its a bypass to the electric trim and tilt. most of these relief valve screws are below the water line, therefore it is made so that saltwater or water will not enter the system when used. It only takes a full turn to engage. any more than that can cause it to leak oil, or contaminate your fluid with water.

[@MrTechReviewDude]

Is there any reason to pay extra for the manufacturers brand fluid such as Yamaha or Johnson compared to something like Pennzoil.

[@captainedc]

ATF will work fine but unfortunately it's not compatable with the seals and will eventually cause them to fail prematurely. ATF in your power steering will do exactly the same thing instead of using power steering fluid.

[@jeffmosher8719]

Then why does Mercury say that you can use it?

[@RICHat22]

Not to disagree on the seals part, but my 1988 Mercury 70 had ATF in it and does not leak a bit. Has for almost 20 years since I acquired it and I just changed it for the first time this weekend. Call to Mercury, they stated Quicksilver trim and steering fluid or Dex/Merc 3 ATF are recommended fluids for this model.

[@steveodem3620]

i have 2002 yamaha outboard 90 hp. when im driving the boat and trim down as i come to a stop it makes popping noise, it only does it when in the water. if its on the trailer it doesnt make this noise, any suggestions as to what it might be ok that i can do? thanks!

[@klzgirl]

I have a 2003 Hydroswift and the trim wont go down. It makes a click noise when you push on the trim but nothing besides that. Any suggestions on what it might be?

[@ReelTeaseFishing]

if the fluid is too low or it has too much air, it will do what you are describing. Hopefully by now you were able to correct it but if not, here is a link to manually lift or lower your outboard. by manually lifting it you will be able to add fluid into the reservoir.

question 4 u buddy,,i have a 1997 mariner 90hp 2stroke motor, would u say a propeller thats 13,25x19 will work well for my motor?..thank you

[@ReelTeaseFishing]

As far as a prop. I wouldnt really be able to tell you. However you can go to www.mercurymarine.com/propellers/prop-selector/# and that will help you out with the proper size prop you need.

[@ReelTeaseFishing]

Hey bud, There is more to that than just a one size fits all. Everything from type of boat to the weight of the boat comes into play. I suggest going to www.mercurymarine.com/propellers/prop-selector/ to dial in on a relatively good prop for your needs

[@chanfe5293]

my trim and tilt went down and didn't come back up. I hear the relay clicking but no sound from the motor. is the motor broken or do I just have to add more liquid? thanks in advance

[@ReelTeaseFishing]

Chan Fe if you hear the clicking then the relay is getting power. Next thing I'd check is to make sure that the actual trim motor is receiving the power. Many times especially in saltwater the connections will corrode. If the cable to the trim motor has power and the trim motor isn't operating the trim motor has failed. They are usually pretty easy to replace by removing 2-4screws and swapping with a new one.

[@chanfe5293]

thank you, it turned out to be a loose wire harness from the blue and green wire.

[@drummerdave4093]

So I have an Ocean Pro 150 Evinrude/Johnson 1993 My trim motor went out on me and I had to use the manual release to raise the motor by hand so i could get home. I replaced the motor and now I can get the motor to lower but it will not raise up. How do I purge the air and fill the fluid once I get to this stage?

[@ThomasKerner-xh7ti]

How often do you recommend that the Tilt Trim Oil be checked?

[@ReelTeaseFishing]

I’m a big believer of, if it’s not broke don’t fix it. (On older outboards) However if you notice it jumps, squeels, make a loud noise, stalls, drops etc then I’d definitely check and add TnT fluid. This is one of those things that doesn’t need replacing or adding. As it’s only needed if a seal leaks.

[@staerkej]

Nice! I got a johnson that goes down fine, but comes up very slow. Last night it didn't want to come up at all. Does that sound like low fluid or a bad relay? where are the relays?

[@TheNicks6]

They have pills for that now. BTW your comment, pure gold.

[@baird5776mullet]

I just read in a comment section where some Johnson manuals say you can use dexron 2 in place of hydraulic fluid,can anyone shed any light on this? Great video by the way.

[@Mynamesalexa]

+kenny baird  Transmission fluid is not 90W GEAR OIL.I had a childhood friend now deceased named JIM BAIRD. From Phila, Pa.R U Related?

[@baird5776mullet]

I don't know,my dad was from Kentucky and i don't think they use 90w gear oil as trim fluid.

[@mudcat72]

+kenny baird , Hydraulic fluid goes in the tilt and trim, not 90 wt gear oil. My Yamaha 150 manual says, "A high grade automatic transmission fluid, Dexron II may be used if Yamalube fluid is not available."

[@baird5776mullet]

mudcat72 Did i EVER sat that 90wt was the same thing????

[@mudcat72]

+kenny baird Of course not. I haven't said that you did. 90 wt oil doesn't belong in the discussion. I have no idea why Arthur mentions it unless he believes 90 wt oil goes in the tilt and trim. Sorry, I was was trying to clear up things by offering what my manual says. So that's two brands of outboard manufacturers manuals that say dexron II is good to go. I bought my transmission fluid to refill it last night.

[@busurdik]

Any way to fill the unit once its stuck on the down position??
