    How to proceed?

    1996 Johnson Ocean Runner 150 hp Got word from a mechanic that my motor has blown a head gasket and as a result my #2 cylinder only pulls 20 psi. He did not pull the engine apart as my boat was still in the water and he wanted me to be able idle to the ramp and pull it out. Oddly (to me), the...

    Trim/tilt fluid low?

    Hi, my buddies 2001 yammaha 4 stroke makes a lot of noise when tilting the motor. It sounds as though there is air in the fluid? Could someone explain the procedure for topping off/purging air or is this some other issue? Thanks.

    Throttle cam roller missing

    I was reading the thread about the throttle cam sleeve but didn't want to hijack the thread. The sleeve on mine ('96 J150EXED) has been cracked for some time and I never thought much about it. Recently the same day I noticed it was gone I noticed the motor was MUCH more responsive to throttle...

In other words, I can grasp it and the top of the shaft moves maybe an inch or so from center, in any direction with little to no effort. This just seems...

    Lower unit fluid

    Hi to all, this is my first post here. I have a 1996 J150EXED and the owner's manual calls for Ultra HPF fluid for the lower unit. The guy at the parts counter said to use Hi Vis instead, that it was better. Can anyone tell me if it is ok and what the difference might be? Thanks in advance...
