    Might try a portable tank if you know someone who has one.

    johnson 70hp 2 stroke 1995 shut down when warm

    Get the compression numbers to make sure the engine is ok and then start the fuel check offs if the compression numbers are still good.

    Do you have a built in tank or are you using portable tanks?

    1968 Evinrude 6hp - 6802C - Gearcase Seal Kit

    Here is something odd and I'm not sure it even helps. When I plug in 6802 in the where I buy parts, just like you it comes up 1967. But when I go to leroysrambilings his chart has it as a 1968. I think that guess of the 67 to 68 has to be the one but then who knows. Another thing, if you click...

    Tough one. Not sure if this helps but this claims to fit that gearcase.

    1991 20HP Evinrude no acceleration

    Well in this long thread you talked about the engine running good but that the motor would jump into high rpm's and the boat would slow down (bad prop) then you quoted that you had a new pump never really saying it had heated up and then all this. Most motors when they heat up and you keep...

    1992 Johnson 15 hard starting

    Put some wd 40 in the cylinders and turn the throttle wide open and run your test again. Make sure you pull it 5 to 8 times or so. Those reading are no good so check your work. Otherwise, yes pull the heads and hope for a bad head gasket. Most likely she toast.

    From what I understand octane is not an issue but stay away from ethanol.

    johnson 70hp 2 stroke 1995 shut down when warm

    And by the way, because I'm not aware of your boating knowledge, you did make sure you have oil in the reservoir? Because if your alarm is malfunctioning and no oil...... (No disrespect intended) Also, you can just check for spark you have to check for GOOD spark. That means a tester that...

    johnson 70hp 2 stroke 1995 shut down when warm

    Well there is the pee stream. That says the pump is pumping. But that doesn't say if it's flowing around the engine. (Thermostat failure or passage ways plugged.) If you have a thermal gun (fairly cheap) you can shoot the heads when warm. Looking for 130 or so. Still think it's the fuel system...

    johnson 70hp 2 stroke 1995 shut down when warm

    Well if it sat for a long time before you purchased it my guess it's fuel related. (Tank, hoses, carbs....) But it can be lots of things. Most on here will want model number, compression test numbers, spark test, etc. Then they will comment.

    1987 Evinrude 110 success

    Awesome, it always rewarding when when you take a guess and it works! Not sure I would go back to the boat mechanic guy anymore.

    1991 20HP Evinrude no acceleration

    I don't think it's overheating but you should check it. Sounds like it never runs fast good. You idle out and when you go to punch it on comes the problems. Could be an electrical component that only fails after heating up or like race says bad wire under the plate.

    1991 20HP Evinrude no acceleration

    No slow mode or safe mode on that motor. Shoot the top of the head with a infrared gun and see your reading. Check plugs like Jimmbo says but I think Racerone is correct. An electrical component is heating up and misfiring. Again, please confirm, motor runs fine and then goes into that mode...

    1991 20HP Evinrude no acceleration

    If that isn't connected correctly or is stripped when you pump the primer ball has will spray out of that area. Easy to check.

    1991 20HP Evinrude no acceleration

    After re-reading, your motor runs fine and then goes into that mode correct? If that is true, it probably is electrical. Do you have a timing light?
