    Super Jet 1990 650 Superjet Coffman Sizzler Dual Cooling water routing

    I just got a new gasket from jet maniac that seems to have been designed to even out the cooling flow to the head from cylinder jackets. Has smaller openings on the side with outlet port and larger ones on the opposite side, this encourages equal flow to the outlet. Also has two 1/8" holes on at...

    I wouldn't mind waiting but I think that's a bit high for a stock 650. It doesn't include the stator or ebox right? I was told by a few experienced members that the engine should run around 300 shipped. Let me know if that works for you.

    Awesome, Im glad to hear your ski is tuned up and ready to rock! :) Something you might do is take a white mechanics pen (that stays on through oil etc) and mark the screw settings on your carb.

    I cant see what the second compression number is, it seems it says 154/ something. Find out what the compression is and let me know your price on it shipped to 96073. Is the engine stock or bored once/twice/etc. Thanks

    Super Jet '90 SN with 701 top end, Power loss and now knocking

    Thanks everyone for your help. I talked more with Bruceski and it seems the best route for me at this point is to find a cheap and complete running 650 and throw it in. I just want to get my brother out on the water with me and not have him disappointed. Im not familiar enough with ski engines...
