My father instilled in me at an early age to make sure the motor is "pissing" before we leave the dock. This lesson has saved me several times. Here in NC we have dirt dobbers that will quickly fill the hole and spoil your trip and has happen to me several times. A quick poke with a small round object and you're back in business.

YOU DID IT...!!! You inspired me to dive in and find the problem with the tell tail on my MERC 250EFI. Get this, a pebble was small enough to get through the block side barb, but too big to get through the tail side exit barb. So every time I stuck a wire hanger up there to clear it, that was just pushing the pebble back into the block....lol

I once had mud dauber wasps fill the telltale hose with dirt. I've found a long thin ziptie works very well for probing the hose for obstructions. It has just the right amount of stiffness & flexibility & won't break off.

[@mjodr]

I just bought my first outboard and the pee hole didn't work, but it looked like there was glue in the hole. I figured since it had a water pressure gauge it somebody plugged it up, otherwise how would the gauge even read pressure? I was wrong because on the second test session all of a sudden whatever was in the pee hole blew out and I'm pretty sure it was a wasp like you said, because they do the same thing all over our backyard in the pool electrical systems and holes in our umbrella poles.

[@THESEXYAPE]

My motor stopped pissing one time because the top fitting of my water tube had broken when I pulled my lower unit off so I could put a new water pump and impeller.... took me forever to figure it out. Needless to say I pulled the broken piece out and jb welded her back together lol. Still holds up to this day

[@nyesgarage4050]

My outboard stopped peeing a few months ago. Noticed it after about a mile past the boat launch. Shut it off and trolled back to the dock fishing along the way. Once I got it home it was just an old torn apart impeller. Had an extra, replaced and good as new. Appreciate the video!

[@Prodagyxx]

You good sir have earned a like and subscribe. I changed my impeller and thermostat, no joy. Watched this, took off the air box, went straight to my fuel cooler blew it out, eureka! It’s peeing now. Bless you, you saved me lots of $$$.

[@nedpalmer7495]

Mud daubbers ( wasps ) use mud to build nests inside the pee lines here in Florida. I keep a wood dowel painted red with a small rag attached, remove before leaving the house. Also keep a 80# mono strip of line (10") to clean out the line.

[@thesaltlifemanshow5522]

A few years ago my buddy and I went up to my girlfriends moms lake house on lake Winona in north eastern indiana. It's a pretty lake but really small for even my boat which is only 17.5 ft long it's a 1978 glastron ssv175 one of the super rare ones that they only made 150 of. By far out of over 50 boats that I have owned over the years. The 70s and 80s glastrons were legendary and the ssv hull design in my opinion is one of the best hull designs ever made. Alot of folks dont know that glastron was responsible for the very first fiberglass boats and they were extremely well built. Both my outboard ssv175 and my IO cv23HD had rock solid transoms and all of the wood that was used in the stringers and such despite being neglected and left outside in the Indiana elements for many years were still very solid. I did however have to redo the flooring and the interior on both boats has been completely customized and modernized. I also have a custom made roof so if necessary I can still cruise in the rain and camp in it as well. My point being the ssv175 had the original 78 mercury tower of power 115hp and it was one of the motors that used the same wiring found in airplanes that when exposed to gas and such the insulation would get rock hard and just crumble to the slightest touch. So I had to redo all of that then on the trip to lake Winona I figured out why they said that the way to stop from drowning in lake Winona was to just stand up because the lake is so shallow. The canal up to her house was rarely used and had lots of plants and fallen limbs and just was filthy and obviously it got sucked up in the water intake clogging it. And we just used some soldering wire to shove into the hose. Which worked. However I learned a very important lesson later. When the fuel was low we decided to trailer up and go to the station. I didnt have a gas can so I simply poured the oil mixture in the tank and added the correct amount of gas for the right ratio. I figured on the 5 miles back to the ramp the boat would be shaken enough as well as the filling of gas to mix the oil into the fuel. However after about ten minutes of running towing a tube with my girlfriend and her friend on it at around 4500rpm suddenly we heard a bang and the motor just stopped dead in its tracks. And after trying to start it I learned it had locked up completely. What's crazy is despite it locking up and having some metal shavings in the piston sleeve and on the spark plug. I added some lucas lubricant and mystery oil to each cylinder. Which freed it right up and after cleaning up the shavings the motor ran just as good as it always did and that cylinder was only five psi lower on compression than the other cylinders. That being said the boat now has a 150 5 year old evinrude and I will never go back to mercury again. My IO has a custom 454 olds with a Volvo out drive. But by far my favorite engine is my seven marine outboard on my tritoon. It smokes past everything and has been super reliable plus looks wise I think they make the best looking motors out there. Anyhow that's my two cents. Good luck with all that you do. Hopefully one day you tear into a seven marine engine and see how they are to service. I know that the cadillac engine in it is very unique and has more computers and doo dads and be bops then I've ever seen.

[@rogeliobravo4927]

Like always great video, seeing your videos is always something new to me, the cooling system in outboards is way different than automotive cars, i dont have a boat yet but i wanna be prepared to try and save money when i can

[@davidwatts6478]

Grass trimmer string is good for cleaning the telltale and checking the hoses. Fairly stiff, but you don't typically have to worry about puncturing the hose. I started keeping a couple of feet onboard a few years ago when I fished shallow marshes a lot. It is available in at least two diameters, maybe more.

[@mattcarter259]

Ive used small mechanics wire to clean the speedo pickup for the drive

[@BIG-DIPPER-56]

Excellent idea ! ! THANKS ! 😎👍

[@johnwalker6420]

I use a bike pump and insert an air nozzle into the tell tale and pump it... .. So far it has worked fine and no issues... If I have an issue with hose blockage I simply just change the hose... Why not have a filter service each year anyway... In saying all that I love these videos as they help me doing a lot of maintenance during the year and hopefully trouble free.

[@avidsledder]

Had minimal discharge from my stbd 150 g2 Evinrude. Engine was running hot at nearly 200 deg. Took it for a simple freshwater flush and after a few seconds without water exiting it “popped” and water began to flow through. Engine ran 60 degrees cooler 15 minutes later

[@mcdonaldmollusca8376]

I always carry fishing line wire because this problem has happened more than once to me. That wire is extremely flexible and can extend up the tubing several inches until you are obstructed by a T or a manifold. Never had to disassemble a manifold yet. But chunks of seaweed or grass are a popular maintenance headache.

Let it run for a minute and checked Temps no issues. Tried a couple more times and still no pee. Now I want to go back at it on Easter Sunday lol.

[@laylow8648]

After winterizing & flushing the motor I put black take over the pisser so insects don't mud it up. Huge help.

[@blaster-zy7xx]

Tape?

[@ozskipper]

Yup.. Always check for water exiting the motor.. Even with Inboard diesels, you check there is water in the exhaust.

[@meax2499]

Another key tip if you think your impeller is bad: Undo the hose flush port and start up the motor. If water comes shooting out at a good rate you can most likely call your impeller good.

[@vr_bob]

Is this regarding muffs?

[@colonelfustercluck486]

Yes, but you must check that your good flow is not because of excess hose water pressure on the muffs.... or hose connection for the motor. So..... drum roll...... I have a plastic drum with water inside it..behind the boat trailer. I lower the motor into it....... start the motor and a few second later the 'tell-tale' (water pissing from the pipe) should start. If it is zero or just dribbles........ you have a problem. If it squirts out water reasonably fast and consistently, your system is going well as far as water cooling is concerned. Yes this is old fashioned........... but it is the same way in testing operation, as it should be working in actual use......

FYI... my 1989 40 hp Mercury Force does not have a tell tail. I panicked the first time I fired it up, looking for the tell tail and did a little research and found out it does not have one. Great video!

[@kevinlynch6799]

If my Honda 200hp outboard is not peeing like a racehorse: With engine running, insert the little 4” straw tube of a compressed air can (like the pressured air cans used on computer keyboards) a little inside the pee tube and give it a quick 1-2 second shot of pressured air. Repeat if necessary a few times. If it is still not peeing well, meaning water is coming out but not strongly, try a very thin piece of String Trimmer or a piece of wire being careful as the hose is made of rubber and if you puncture it you have a repair ahead of you. Since using the pressured air trick a mechanic taught me I have not had any issues in unblocking the pee hole. I do carry two cans just in case I have to help someone else in the remote areas I usually fish.

[@nickkostakis9600]

Great video and very informative thank you very much from Sydney Australia

[@MadisonFishing]

Taking the lower unit off and blowing out the hose with an air hose (120+ psi) clears most clogged really quick. I’ve had little sand particles and other random tiny objects (probably rubber from the impeller) eject from the system and cuts out a lot of trouble shooting the coolant lines.

[@e.a.b8278]

[@saoirse2345]

1st Step. I have an 8hp Mercury 4=stroke - Since I live in an area with much seagrass, it plugs often. Bought a 'Double Tough' mini CO2 motorcycle tire inflator and when the pee-hole plugs I just shoot a small anount of CO2 into the pee-hole and it clears immediately.. Simple.

[@jamesglavich1426]

I put a zip tie in the outlet to keep mud daubers out. I remove it before launch, a couple times I forgot, you still get the stream past the flat sides of the zip tie, but looks different and then realize it needs to be removed. This helps protect the discharge end from pluggin

[@user-sf8xx4ds3r]

[@philmaxey5559]

Weed Wacker line Works great for cleaning that drain and you leave it in when you're not using the boat .

[@monkeywithawrench27]

For anyone coming here who happens to be working on an old Johnson or Evinrude (pre-80s models) they don't have tell tales like newer engines. They do have a small exhaust port on the below the engine that sorta looks like a tell tale and spits water like a tell tale, but it's not. These ports won't spit water until the thermostat opens once the motor is warmed up, and they often won't spit water when ran on flush muffs because there's not enough back pressure on the lower exhaust to force water and exhaust out of this indicator. So if you have an old Johnson or Evinrude like this, you may want to try running it in a bucket or barrel of water (or on the boat in the water) until it warms up before you start taking stuff apart.

[@nitrorc1623]

Nice, that it was only the fuel cooler. I Kinda hoped you'd have to dig deeper, still I am happy for the engine, owner and you, so you did not need to open up the power head like I once had on my 15hp 2 stroke. It had more than 600 working hours as all of a sudden steam started to come out the indicator. I've shut down the ouboard immediately. Repair shop changed the impeller and removed the thermal switch on the powerhead. Of course it did nothing. I decided I wanted to save the good old two stroke and removed the powerhead. The problem was of course all sorts of sediments being deployed in the cooling water area at the bottom of the powerhead (of course all arround the cylinders too, but on a 2 stroke it's a piece of cake to clean the areas arround the cylinders, because there are no valves having to mess arround with), blocking the free exit of the cooling water. I had to use a small hammer and a 3mm steel wire at some points to literally blast out the sediments. Respect to the japanese as they've thought about this and placed 2 very convenient openings for the steel wire to reach all the (hidden area) inside with ease. Operation suceeded (thermal switch installed again (it had to be or else the engine was running too cold now as it had all the cooling water as if it was new) my friend whom I've sold the outboard has been running it for 5 years now and counting. If this happens again I will have the job done in less than 2 hours. Now I have a 40hp 2 stroke and for now no such problems.

Took the day off from work planning to go fishing. Drove to the launch ramp early in the morning, and put the boat in the water. Noticed that the P stream was not working. Took the boat home, canceled my fishing trip, and ordered a new impeller to replace in the engine. Ripped the whole lower half of the motor off to replace the impeller. Moved it into the driveway and started it up, still no water out the P hole. Come to find out it was simply a seed stuck in the hole discharge. Couldn’t believe it. A paper clip worked wonders to clean it out.

Great walk-through. Had no idea water cooled so much more than just cylinders in these big motors. Got an issue at the opposite end of the scale. Little biddy Johnson 3.5 hp kicker. No water out the telltale but there IS water coming out 4 holes on the trailing edge of the leg about halfway up the engine. Looks like water and exhaust come out this same area. This would seem to suggest the impeller is pushing water through the engine but I don't know if the telltale is up line or down line of these exhaust holes that are also shooting water...

[@grahamcull4077]

I had a low hp merc which wasn’t peeing properly. I accidentally fixed it by driving in shallow sandy bottom. The mixture of a little sand picked up in cooling water gave the cooling system a good clean out with a blast of sand. Don’t ask me what ratio of sand to water. It worked

I used to keep a piece of wire or line in the hole while the boat is stored at home. Now with a new boat I keep a full engine cover over the engine. You got to protect your pee hole! Bugs will build dust, dirt,etc... inside that hole sometimes enough to notice a difference in the stream within 2 days. Look at every hole of any kind you don't want a mud dobber filling in. They will do it in a shorter period of time than you think

[@Tyler-kw9ce]

Took some 80lb leader and ran it up there to clear mud dobber remnants. Had another time recently it wouldn't pee at all. Went and disconnected from the inside of the engine started to trickle. And seeing as I only had to run about 3/4 mile to where I was fishing i went with it. Starting peeing healthy by the end of the night fishing. So I got it in for a new impeller and lower unit service. Can't be too careful!

Welcome!

I have a very old (1986) mercury black max oil injected 200 hp low hours. Had for two plus years. I was going to exercise the motor this fall. No tell tale. Immediate stop. I removed bottom of motor with help from youtube. Easy pezke. Water impeller was me!ted and very non functional. New water pump impeller kit from mecury. Reinstalled today, great tell tale, almost twice the water pressure. Runs great. Gotta love an older merc carbed two stroke oil injected motor. Lay people can work on them. Like owning an old school 1970 chevy 350 pickup. Old school but I love it. Paired to a 1990 WAC 20 footer. Great boat, great motor.

Well I change my pump, thermostat,plunger was melted …replace all and still no tell tail ,back flush with garden hose and the lines were unplug.and that did it..back on the water…yes

I got my small Yamaha 8HP not peeing (at all!) anymore whatever the RPM after the winter season (out of water of course! Also I'm in Lake region... unsalty). I warm up the engine a bit, then I injected anti-lime (3cl or 1oz) with a syringe directly from the small end, waited 5-10min, and started again the engine: full water pee pressure like I never saw it before!! Love that easy & cheap fix... makes your day. Note: I also heared about injecting WD40 from the same small end... In the case of this big engine on the video, a bit of air pressure would have helped too.

[@drummergrl1000]

what's the small end mean?

[@KitsFishing]

Iv never had a problem with my outboard but my friend has. He said he connected an airline to output pipe and blew it out back the way it came in. I like your fix much better

[@Gooselip]

Put my boat in today and the hose was completely clogged with bugs and crap, cleaned it out working great

Thanks for sharing this video

[@Winterrowd3209]

Could you show more details on how to get to fuel cooler - please

[@DirtMcGert29054]

Compressed air up the tell tail while running fixed mine

[@ickess]

I did this to fix a clog in the fuel line of my oil burner.

[@hankschrader149]

I did compressed air but it wasn't running so I'll try again! It worked for awhile then must've clogged up again
