    Supposed seized water pump bearing

    Volvo Penta 5.7 GXI-G 2006 I had a problem this summer (which unfortunately did not turn well at the end due to an unlikely serie of events), while reaching my destination with the boat I slowed down to absorb the wave of a big boat, then accelerating again I heard a strange noise in the engine...

    F150 - Exhaust Guide change - Photos, tips and question

    I have been a bit misleaded by the mechanics that sold me the engine, they did not foresee to change some gaskets and apparently feigned to see an important issue, so in order for people not to have the same problems, here are some tips and photo to change the exhaust guide, which is probably...

    Probable stupid question about the gear shift assembly

    I am replacing my old Yam 1990 225cv that finally died by a 150cv 4 stroke from 2008. But I have to replace the guide exhaust on the new one (things would be too easy if not...), I think that's about the worst part to replace but got some training disassembling the old engine and probably know...

    Tach showing wrong rpms

    The engine is a Yamaha 225 HP 2 stroke 1990. A strange thing occured last time I used it, on the way back the tach was showing about twice the rpms, usually I go 3500 rpms, the engine can go up to 6000, and the tach was showing 6000/7000 rpms, then slowing down before arriving it was showing...

    Yam 225 - How can we get one pulser coil only ?

    The engine is Yamaha 225 HP 2st V6 year 1990 Using the service manual to test pulser coils, it appears the one dealing with cylinders 1 and 4 shows no continuity, the two others show a correct resistance. While the engine is running, it looks like indeed that cylinders 1 and 4 are not working...

    Yamaha 225hp - computer bypassed

    While starting my Yamaha 225hp 1990 BETO everything looks fine except that it does behave as if the computer was bypassed and the motor was in protection mode. Question : there should not be a lot of things that cause the computer to be bypassed, what are they so I can check one by one ? (see...

    Yamaha 225hp 2str Crank Position Sensor test

    How can we check if the crank position sensor is working or not ? I have seen different posts about testing the CPS but not saying how, mine shows a correct impedance while engine is not running but it looks like there is almost no continuity while engine is running (very high impedance)

    Yamaha 225 thermo-sensor / prime start / computer question

    Hi, I have a Yamaha 225 BETO 2 str V6 year 1990 (Serial Nb 6K7 etc). I will not go trhough everything I did recently to try having it work perfectly (did not work since 4 years), the threads on this forum really helped me, basically among other problems now fixed, the engine did not want to...
