    Re: What color is a 1998 SXI Pro motor?

    I'm kinda confusedi about this topic ever since I got my ski...I bought an sxi pro with a sticker on the inside of the hull saying that the hull is made in 1998, the paint and graphics are matching to that year model but the engine in it is grey...it's a big pin for sure cause I did a top end rebuild on it, but can somebody tell me if there's a chance that it's a genuin pro engine or someone swapped a non pro engine into my ski?

    some early sxi had the grey motor, i believe the porting on the grey motor was better than that of the teal ..

    The Sxi Pro was the teal engine with Mikuni carbs instead of Keihin's.
    I don.t agree that "the porting on the grey motor was better than that of the teal"
    It depends on what you looking for in your set up. The teal cylinder can turn more RPM

    If you have a gray motor, look to see how many intake bolts it has. If it has 10 its a small pin, if it has 12 its a big pin. In 1995 only, the first big pin was put in the sxi ( not pro) with dual keihins. It was also installed in the 1995 zxi 750 and sts 750 ( not st). Those are the only 3 skis I am aware of that came factory with a gray big pin motor. That cylinder and cases were different than all of the other big pin motors that came after it.
    In 1995 they produced both big pin and small pin 750's, both gray.
    The 1996 sxi was the first year with the teal motor.
    Your 1998 should have come with a teal big pin. It must have been replaced at some point in its life.

    Also, I believe the 1995 gray, big pin cylinder has a " 24 " stamped on it.

    I took a closer look at it today and found out the following: the cylinder has a 24 stamp and B engraved onto it, the head has a C mark on the second blank cooling outlet, and both the engine number and hull number say it's a js750B. Also the carbs on it are two mikunis sitting on a 12 bolt intake, and it's a big pin for sure since I changed the top end on it and used 22mm pins. Also to make matters more confusing the intake is teal an so are the rubber engine mounts...
