    What's the lifespan of a GP1200 engine?

    I'm fairly new to pwcs, so just curious, what's the average lifespan of this engine? I've got 116 hours on a 2000 GP1200 and it runs well. Can I expect 200+ hours or will compression start going away earlier than that? I've a friend with a 12 year old 750 ski that has over 400 hours and he's run the heck out of it. It smokes a little on idle but still runs like a champ.

    Thanks!
    Eric

    Not sure on gp1200, but my 2005 Gp1300r has approx 280 hrs on it and still running strong, Yamaha builds some tough long lasting engines... Check compression, and if both cylinders are close , ride pee out of it and have fun.

    hahah your quick! Yes, your correct, to preserve engine life, I always pull one sparkplug wire and run off the other 2 cylinders, so I think in terms of having a 2cylinder engine I alternate it everytime out so while my hour meter shows 280 hours, in actuality each of the cylinders have less then 2/3 that (190hrs) well.. except for cylinder 2... a couple weeks in a row I forgot to plug it back in and unplug #3


    OK if all THREE cylinders are close in compression

    My gp1200r (2001) ski has 190 hours on it, and the compression is still there and the ski runs nice. Never had any issues with it. Just recently did all the work in my sig.
