    A few questions about 1200STXR and STX-15f

    My next machine will be on of these two and since I am new to the Kawasaki world and I have a few question for actual owners:

    1) How does this hull handle compared to the GPR? Especially rough water.

    2) Are Kawis low maintenance like Yamahas were you don't have to grease the grease shaft or change jet pump oil?

    3) Can you get away with not pumping the engine and exhaust with anti freeze for winter like on Yamahas?

    hey the only maintence on a 15f is to change the engine oil and plugs once a year. You should throw some antifreze in for the winter but really only need to rev it out of the water a few times to dry it out.

    its pretty good in the chop and a really dry ride but the bigger hull 300x is better in the heavy chop

    the 15f is really good on fuel only 11GPH wide open throttle mine is doing about 65MPH with the Riva kit installed.

    Maintenance is the same as any ski.

    The STX hull is a very good all-rounder. The 300x hull is obviously better, but the STX hull feels nimble.

    The 15F uses heaps less fuel than the R but if you want to mod go the R (if you don't care about fuel costs)

    They are very stable compared to the gpr and still a lot of fun to toss around, the majority of race hulls are based on the stx hull. the 12, and 15 are bullteproof, I don't have experience with the stx-r but they have a cult following.

    Maintenance

    Flush cooling system every time with engine running
    blow out the waterbox with engine running but hose off
    put antisieze on the spark plug threads
    change the oil every 50 hours
    keep a trickle charger on the battery

    Things to look out for on a used ski (any stx)
    check compression
    check the display looks good and functions properly (if submerged they can fry in very short order) if you have any doubt avoid it because they are expensive
    check for water leaks around the exhaust pipe on the bottom near the waterbox and under the intake manifold (odds are people wont take as good of care as you will so)


    Otherwise there is not much that can break, they are dead simple

    210-215 warm on seated rings with the throttle wide. The key thing is that they are close to each other.
