Mercruiser monitor leaking gear lube.

If your monitor is leaking gear lube check this first before you do anything else. #mercruiser #Mercruisermonitor #Mercruiserleaking

[@jameswhiteman6901]

Simple. Thanks for sharing mate from Australia.....great lesson.

[@tommcgrath691]

I am having an issue now with gear lube leaking fast. Didnt think it was coming from the reservoir because I couldnt see any in the bilge area. I did notice the reservoir cap wasnt seating properly when I refilled it. I will check this out and report back, thanks for posting this.

[@outdoorswithcam]

There is only a few places it can leak. One of my videos I have a homemaid pressure tester I made out of parts around the garage.

[@chrisweis]

Thanks for this tip!

[@outdoorswithcam]

Happy to help!

[@DIGOLOGIST]

Good to know. I just bought a 2000 Bayliner capri. Thanks.

[@novarestoration4473]

Digologist me too. 2000 Bayliner Capri 2050lx with a 5.0. 3 weeks ago. Lol. I just change steering cable. Now I have gear lube leaking from the back. I don’t know why.

[@DIGOLOGIST]

@@novarestoration4473 Good luck with you boat! I have to get a idle problem figured out. Every boat mechanic I call never returns my call. Hope it goes well for you. I also have a 2k Chevy Silverado. a 20 year old truck pulling a 20 year old boat !

[@drjeffd]

Good to know to about the cap. My advice is don’t store you boat with the prop up it stresses the bellows and tubs between the transom and lower unit

[@outdoorswithcam]

That is so true! It takes on memory. You see them up all winter on boat.

[@henrycagle7827]

Don’t store your prop up, drop it when you get home. Cause and effect undue stress and strain on outboard,bellows hydraulic lines,both water and oil seepage of leakage of internal gaskets

[@outdoorswithcam]

Couldn't agree more. Always lower it when I get home. Think of all the people that leave it up over the winter and what that does to the bellows. See them up all over town in the winter

[@drchris311]

Good info Ty I’m in Louisville but never take my boat on Ohio

[@outdoorswithcam]

You should. About froze for thunder over Louisville. I know you don't have the beaches like we do down river. I trailer to Lake Cumberland couple times a year for poker run and thunder run. I hate land locked lakes like rough river. The thing I like about the river is you never know what you will see. The Pinta, river boats, River clean up barge. I have seen space rockets on barges. My favorite past time is bow fishing and arrow head hunting the banks of the Ohio. I can find private places to anchor or camp on an beach/island. The Ohio river is clear enough right now you can see the propeller...

[@ernestpatterson823]

80 miles... What size gas tank on that boat

[@mtman69]

have small leak on bottom of monitor tank, nothing coming out of top cap. There is a tab thing on bottom of tank next to wires going into tank is this a on off type valve and if so what position should it be in as that appiers to be where the leak is coming from?

[@outdoorswithcam]

There is no value. If you look close the wire go to the low oil sensor. There is expoxe around it. That is where they start to leak. expesatlly in the heat. They are not that expense. just replace the whole unit. They are $40. Some people put silicone around it.

[@life_wealth]

Where did you bought the washer?

[@outdoorswithcam]

You have to buy a new cap $10. www.boats.net/product/mercury/8067271?gclid=Cj0KCQjw4uaUBhC8ARIsANUuDjWhzknD26_dmGkC9KCcUXEFjG4gG1-dlU29-LVLFUh73_HekmmlmigaAjLUEALw_wcB You can get whole new bottle here www.wholesalemarine.com/bottle-assy-oil-drive-mercury-mercruiser-806193a46.html?gclid=Cj0KCQjw4uaUBhC8ARIsANUuDjU0Prap4M7DOR80_BXZiUYwQQOLX_BBdvKcsOO0RdywK29A5T23pEYaAideEALw_wcB www.amazon.com/Monitor-Reservoir-Bottle-MerCruiser-806193A48/dp/B085Z59S5X/ref=pd_lpo_3?pd_rd_i=B085Z59S5X&psc=1

Nice Video!! Nice Boat!! have almost same issue except my gear oil leaking through my weep hole rapidly just started happening. boats been sitting for a couple of weeks and noticed the drip on the driveway. any info would be helpful

[@outdoorswithcam]

Leaking where? Hole between the cavitation plates. Then its a couple dollar seal that goes around the shaft. getting to it is the problem.

[@frankletizia7835]

I notice my reservoir had oil in it started it up , Then I start it up ran my antifreeze through block I notice no oil in reservoir . could I done damage to drive ? I did not put in gear .

[@outdoorswithcam]

Dont understand your question. The reservoir hold extra oil. Common to have an air bubble in the upper part of drive. Doesn't mater if its in gear or not the drive shaft is turning. Probably won;t hurt anything if there is no load on it for short time.

[@andredesouza9767]

I have the same leak on the leg :(

[@dancindavey1515]

Tried calling boat dealers to see if they carried the warsher. Didn’t know what I was talking about.

where does that hose attach too from the reservoir

[@outdoorswithcam]

To the back of the lower where it comes through the transom.

Hi I m loosing gear oil To. Undernith thr leg is a small pipe It was cracked and disconected Can this be problem of mine oil dissaoerence?

[@outdoorswithcam]

That pipe is a water pipe from the impeller. That sends water up from the impeller to the engine. Watch your temp. There is only 5 places gear lube can leak. Propeller shat seal, drive shaft seal, O ring between upper and lower and the upper shaft. You look for the leak also check the bilge. You can make a pressure checker like I did. Its in one of my videos.

[@franciscobernal8755]

When u had the leak on the drive did the water came oily and black when u test it at home?

[@outdoorswithcam]

No but there would be a oil shin on the concert. Rainbow... But water was clear

[@lanapfeifer6339]

just watched for a long, long time but i think i learned something. i forgot what it was.

[@peregrinorosero4390]

What kind oil go inside this reservoir ??

[@outdoorswithcam]

90 weight. Don't put the quiksilver from walmart in there. You will see a big difference between mercrusier gear lub and quiksilver. Both say 85W90 but there is a viscosity difference...

[@gerardbourassa603]

My gear lube is leaking from the plastic fitting on the stern drive

[@outdoorswithcam]

Well you need to replace it. I always wondered how long these plastic parts are going to last on these newer boats.

[@leugofficial9266]

I just bought a crownline and the gear lube goes empty on the reserve and seems to go under the engine. Could that be that one of the hoses are bad?

[@outdoorswithcam]

YOu can follow the line back with your finger and see if any oil gets on your finger. If it coming into the bilge below the drive shaft it is the drive shaft seal on the lower unit. You have to pull the lower unit to replace it. At that point you will know because your bellows will be full of oil. Take a mirror or camera and look right under the drive shaft. Or stick your finger under the drive shaft.

[@leugofficial9266]

Cam miller thank you!

[@addihoudijk3854]

Hey, I had the same problem last weekend. I think the cap wasn,t tightened properly. Today I tested at high rpm with the cap off and found that the level was raising quickly, until I screwed the cap back on. Is it normal for the gear oil to raise like that? Is it alll due to temperature increase from the drive?

[@outdoorswithcam]

@@addihoudijk3854 Its the temp of the oil not pressure. There is a one way value on top of the cap that allows air in but holds the pressure. Its really not much pressure. If you pressue test your lower unit and exced like 12-14lbs you will blow the seals out. So yes it is normal for the oil level to rise as it heats up if you don't have the cap on...

[@outdoorswithcam]

@@addihoudijk3854 Don't forget the rubber washer that goes under the cap. That is what my video was about. I had taken the washer off to clean when I winterized the boat and forgot to put it back. Next spring had oil everywhere because that washer wasn't there to seal it off

[@toontown1221]

Can you just pour the gear lube directly in there the reservoir

[@outdoorswithcam]

you have to add from the bottom till comes out vent then top off monitor-reservoir

[@jsm3876]

It seems to me the gear lube monitor causes more problems than it solves, can you cancel it???

[@outdoorswithcam]

It controls pressure. When it warms up you will see level raise. My old OMC doesn't have a monitor. There was a void at the top for pressure. SO yes I guess you could plug the hose off.

[@jsm3876]

@@outdoorswithcam i am trying to understand how it works, because mine has a leak where i have to fill it up every time i go out and its not my lower unit, so does the lube circulate up into the monitor?

[@outdoorswithcam]

@@jsm3876 Where is it leaking??? No it is gravity feed. Also hot/cold expansion. But it doesn't circulate. If your level drops and there is not oil on resevor/hose or in bilge you got a problem. There is an O ring/seal on the drive shaft. When its cold and pressure test it holds pressure. But when it gets hot it will slowly leak oil into the water. It can sit all winter and not leak a drop but when it warms up it leaks into water. So if your level is dropping and there is no oil in the bilge thats where its leaking....

[@outdoorswithcam]

@@jsm3876 It doesn't move up except for heat expansion. Its gravity flow down. There is no pump in lower unit. It is filled with gear lube that moves with the gears. Just like the oil in a diffential in rear end of car.

[@jsm3876]

@@outdoorswithcam it's definitely in the bilge, all of It.

[@s3adrag0n]

Sorry but, almost 10 minutes to tell how to fix an issue? I couldn't even find out what the issue is after 2 minutes. You need to shorten you video and get to the point--i couldn't finish watching it.
