    Bilge pump

    Just curious if anyone knows what a stock 1990 - 650 bilge pump is for GPH ? When I put my finger on the tube end , I can feel air pull but just barely. I will probably put a regular bilge pump in regardless but just curious.

    62N ?

    Curious- has anyone ever heard of a 62N motor ? Mis - stamp maybe ? This is the number that is stamped on my motor. I've googled it to no avail. Motor also says J700E on the Yamaha stamp. Ski is a 1994 SN . Realise that motor might not be original to the ski.

    650 to 701 swap

    Curious, can a 1990 650 engine be swapped out for a 1994 701 engine pretty easily ? The 1990 is in a Superjet . The 1994 would be coming out of a Waverunner lll. I have not seen the Waverunner yet . Would the e box be the same also ? Size and dimensions for e box and engine ?

    Exhaust leak

    Just put engine back in my Superjet and dummy me forgot that there was an exhaust leak that started last Fall . Had the engine out all Winter and the leak totally slipped my mind ( brainless wonder that I am ). Leak is small so going to run it while doing work on my primary ski . Gotta have one...

    Intermittant misfire

    1994 SN - 701 . Ski runs great until about 15 minutes or so . Engine then misfires . Best way to describe it is a low decibel machine gun like fire . Can not get RPMs up . After about 5 minutes , it clears right up for about 5 minutes or so and then does it again . Last time that it did it...

    Ski bogs

    Not a mechanic. Ski usually runs good and is responsive first or two jumps . Seems like when I go over a few boat waves while throttling it or come out of a slide - when I hit the throttle it bogs down . If I feather throttle , it usually catches and rpms increase . Carb, Stator - Ideas ? .

    Impeller question

    I have a 1990 SN stock 650 with stock impeller. I don't care about speed only fast takeoffs and jumping . I have a 15/19 impeller laying around . Would that impeller be ok or too steep for it ?
