Im not familiar in the terminology of outboards but you lifted the spark plug covers and didnt lift the head to see the water passages around your cylinders. you can literally just have salt deposits sitting there causing the water to inefficiently cool the block

It’s your poppet valve or thermostat Change them both Thermostat control the temp flow The poppet valve controls the high rpm flow. Heating when running 🤦🏻‍♀️ cooling when idling says poppet valve to me.

I think people should always have a temp gauge as well.

What boat is it on? Please let me know.

I removed the thermostat… leaving me with two channels to back flush with the garden hose ! The one pushed dark nasty water out of the center of the propeller… hopefully thats my problem !

I know this is old video but there a pop-off valve on the side of your motor that might be bad need to check that

I could really do without the music

Just noticed that the description explains the problem. I have the exact same problem with the exact same motor, but realized that it really only happens when I idle a lot or troll in no-wake zones a lot. So I think mine is also due to not quite enough water/pressure going through the system. When running it at higher RPMs it seems to generate more water pressure are the problem doesn't occur.

Try putting on a Wisconsin sweatshirt and going back through the steps ... lol. I don't know, i'd check the heat sensor. Prob have to swap it out, but I have the identical motor and a similar sounding lake that I boat at lately.... Mine overheats every time after about 1-1.5 hours of running it at various speeds/RPMs. I think mine is likely something similar as mine makes pee pee but haven't checked further upstream from that. Usually I clean off the water intake plates and let it cool for a few minutes and it's good again..... also seems to happen far more often after trolling through about a mile no-wake zone.... so maybe the water pump in this one just doesn't pump enough at low RPMs

Check your aisle. You probably have a blown headgasket

Do yourself a favor and get rid of the music. I wanted to hear you not the tunes.

FIX!! YOU NEED MUFFS THAT SUPPLY WATER FROM BOTH SIDES! SINGLE SIDED MUFFS DON’T SUPPLY ENOUGH WATER FLOW.

😅😂😅😂😅😂 Thermostat the whole time 😅😅😅 And you broke the seals on those gaskets and reused them 😅...Stick to the pen and pencils... Take it to a Mechanic next time 😅😂..All those bolts were supposed to be torqued 😅😂😅...Very funny to say the least...!

Definitely the poppet valve. Dont remove all the wires you can take the screws out of the main plate and move it a side.

Did you change the poppet valve? If your overheating even when the motor is peeing it's most likely the poppet valve.

You did great buddy. Pulled that puppy to pieces and figured it out eventually. These are the best lessons.

Have you tried removing the gearbox and connecting the hose pipe to the water feed pipe and run the engine , this is so you have a direct water feed and let the engine run checking the exhaust plate between the cylinders which should stay cool enough to put your hands on ? Also remove the thermostat and water should be coming out as the water pressure from the hose pipe is acting like you are moving , if nothing is coming out then there's a blockage below the engine ?! There can be a build up of dirt or a broken water pump impeller pieces stuck in n the feed tube or the housing area below the engine !

You don’t know much about outboards

You got to pull the heads off and cii look clean the passages

Spring loaded

Change poppet valve when you change water pump every time

Chunks of my impeller got sucked up into the head and was clogging the water passages in a few spots

i literally just had the same issues with over heating only i found the issue, after back flushing and disassembling the entire disassemble-able parts of the water flows i found my issue was fragmented impeller peices located in the lower unit directly from the impeller pump to the feed tube the pump goes to up about 9inches into the pipe was an entire 6 peices of rubber blades now my engine ran with water during months of running before i just got sick of never going over 2400rpm, back flushing alone couldnt get the fragments out, i ended up taking a long wire and bent a tiny hook in the end and pulled each peice out one at a time. my engine seemed to run water only causing overheating when the water pressure sensor was plugged in, yes in. but this just goes to show that somtimes you really need to look hard for those peices as black in a black pipe can be mistakenly overlooked. hope this helped :)

I like the porno music i n background

Pull the heads

Pop it valve on side of motor. It regulates like thermostats😮

leaking head gasket?

I got the same problem but when my light come on the motor is starts to run ruff like a bad skip l,m going to try new sensor.Get back with me

bad music

4 yrs ago ....... And the fellow never told us "The Rest Of The Story".... Man I hate it when they do that ! ! ! ! ! ! ! ! !

Do u have to pull that cover to remove that tempatire sensor

I am the same way just replace my water pump an it ain’t pumping

Gas an a liter 😂😂😂

Take it to the lake and use a thermal heat gun and see which head is getting hot . Also , big Yamaha motors don't like to run on a water hose very long . Test run it on the trailer at the boat ramp , alot of times it will cool better than on a water hose . After that , revisit your water pump and your water tube from the pump to the power head , it's copper and older motors they can have rot holes in them .

Did you try putting it in some rice?

I’m not positive, but doesn’t that engine have two thermostats??

Are you sure you roll the new impeller in the correct direction

My goal here is not to screw it up too bad. Man that’s a mantra to live by 👍

@TheHardWay Can you elaborate on what metal tab you bent on the water pump install? Than you!

How's the boat? What ever happened to it?

Use a tub not a hose and when it over heats disconnect one temp sensor at a time to isolate which side make sure inside of block is not clogged with calcium

The poppet valve could be opening under load. The heads are clogged up.

Take a water hose stick on the thermostat hole and turn it on I blowed out a 85hp evenrude that way

Hello, if you peel logs in May/June it will come off way faster.

I had a similar problem. Discovered it was the sensor gauge. My mechanic loaned me one to try and it worked. Found a new one on line and ordered it. $138 cost solved my problem.

Rumor has it he eventually solved the problem by the tried and true method of buying another engine.

Look at the common denominators first. Such as, the most likely culprit... 1. Has the dog been out in the boat on the lake when this overheating happens? Because every time you ignored him/her and went to start the motor instead of throwing the toy, I literally saw him/her walk over and intentionally stand on the water hose.

Just because you're poppet valve looks good does not mean it is good the spring has a tension on it that if it is not strong enough it will let water bypass the motor and go straight out through your drive you need to replace the spring on the pocket valve in order to make it work correctly the spring is set up at a certain tension so it will not let water leave the engine until there's enough pressure from the pump at a higher RPM at idle you will get a overheating alarm if the weight if the spring is loose

Stop while you ahead.

Did you find out what it was i’m going through same thing i changed water jacket gaskets water passages or good water flowing everywhere i don’t get it
