    There are actually several MSX 4-tec conversions running around. GGG, beerdart both made one, plus the one overseas. Threads in the conversion forum, iirc.

    The fuel pressure regulator mounting MUST be repaired as part of this job. It's not optional.

    Good catch! No, that is not at all normal if the battery and injector bus are shorted together. EMM problem, most likely.

    Welcome to Greenhulk!

    Good job doing some homework first :)

    If you have an OEM stator (not aftermarket) then the EMM is the prime suspect. I (via Lakeside Tech) will be glad to help.

    EMM testing is offered for a nominal fee, so no concerns about committing to a full repair.

    Stator testing is a desirable next step.

    Revving high when out of the water is very typical for these machines, putting the ski in reverse is recommended to keep it to the 3400 RPM reverse limit.

    Your next step should be to measure...

    Welcome to Greenhulk!

    A key measurement is voltage on the white/red wire (common to all three injectors). As a quick (but inaccurate) test, you can unplug an injector to get access to the...

    Starting in reverse is always a good idea when out of the water. But overboost will only occur under full acceleration under load.

    Swap ECU'S then you'll have another data point.

    The Bosch ECU'S are VERY reliable. And you can swap ECU'S between skis. The only thing to be aware of is the adaption values may not line up at first, which can lead to overboost events until it...

    Nice analysis, but when there are epoxies available that have better performance at temperature, why take the risk?

    Good job! Be sure to count the motor mount shims, and verify vs the writing on the hull next to each mount.

    Awesome! You should seriously consider selling those. Perhaps Randy at weberpower.com would be interested in stocking them in the US.

    I do not think that would work well, its peel strength degrades by a factor of 15 at 180 deg F. (Many epoxies get soft at elevated temperatures).
