    1999 genesis with blown cylinder

    Help Newbie here. Little history of myself new to pwc's work as auto mechanic and some outboards. I have a 99 genesis with 1200 ficht and swamped the cylinder and broke it apart along with the cooling collector have a line on a 1050 motor with bad compression on one cylinder. Would the cylinders from the 1050 work on the 1200?

    Red engine 1200 (1165cc) cylinders are different bore and porting than 1050 cylinders.

    You can find more info about the Ficht engine and common maintenance items via my signature links.

    Be aware that the original wire harnesses in the 1999 Genesis are known to develop corrosion problems, mostly at the wire splices. A bad wire harness can cause all sorts of strange problems, so take the time to inspect. It is possible your machine has already had the wire harness replaced, but check anyways.

    Water ingestion and hydraulic lock can also damage the connecting rod and/or the crank shaft. Inspect thoroughly for damage down there before putting the engine back together.

    The is an engine break-in process outlined in there somewhere, or in the Tech/FAQ sections on here.

    The key is to heat cycle the engine, and use incrementally more throttle more often as the cycles progress. It doesn't take that long to complete, by the end of the first full tank of fuel you are basically done.

    Varying the throttle during break-in minimizes resonances that might create uneven cylinder wall wear.

    Oh, and a slightly increased oil ratio during break-in.
