    I can't necessarily correlate the hood effecting idle with the runaway unless there is a issue with the throttle cable getting in a bind. But things to check for a true "runaway" are air leaks, idle...

    I'm fairly confident the check valves for SBN I-Body carbs (Power Valve motor carbs) are larger diameter than the regular SBN carbs (earlier non-PV motor carbs).

    They are the same hulls with different engine mounts. I can't say with certainty if the 1200 hulls have the front engine mounts drilled and threaded for the 800 engine or not but the hull is made...

    Just a warning if it has issues beyond electrical and has engine issues. Very easy to drop $3k plus on a rebuild. SC probably needs rebuilt also.

    Have you jumped the solenoid to do a crank test...

    It’s on the list of “skis I really really want to ride”. I like the look too. They remind me of raiders in the nose. Not like the behemoth noses of all the performance “big skis”.

    I can’t speak for him, but for me it’s the fact that these “2 seaters” are just massive jetskis anymore. I recently picked up a project 08 PX myself and can’t see how I would enjoy throwing around a...

    That was my first thought when watching the video that was leaked ahead of time. That GP engine access is pitiful and completely ruins the aesthetics. Why even keep the engine cover at that point...

    I don't see any reason to believe that won't be adequate. What pressure do you plan to set the AFPR? Factory is in the 40-50 range correct?
