    Excuse me. Are you the originator of this topic?. I was replying to the originator "attnondeck" of the 300 sx mods question. Are you same person? I was doing the same as others who replied by giving a suggestion as well. And no, I am not worried about how you spend your money. Unfortunately, in social media we all get answers that we don't like. That's just the way it is.
    On those small engines it takes alot to get more performance which turns into a costly project. So maybe putting in a more powerful engine could yield the results you are seeking.
    I looked at the bottom posting and the owner , attnondeck lists a 90 SJ 701, 90 550sx and 94 FX1 ski's that he has. Still I was just offering up a suggestion. That's all.

    I wish you had done a little more research on installing 440 pumps before
    you recorded the video. Your silicone seal example was certainly the easy way.

    Did you try using a breaker bar and heat before you cut that impeller?
    I used a cheap box end wrench to remove oem 440 impellers.

    You should inspect the bilge anti siphon fitting inside your hull.

    Anyone know what the stock 300 engine peak rpms are? I have ready anywhere from 4500-6000 with a 6500 rev limiter.

    I have had then not come off before, after using PB blaster, an Acetylene torch and every tool known to modern man I did the same thing, no shame in it if it won't come off any other way.

    Stock peak HP is at 6000rpm, as far as the revlimiter
    I don't know, but I would bet on 8000rpm.

    My 300 never hit the revlimiter as easy as an early
    Yamaha does.

    I would also guess the JS300 Kerker peak hp@6500rpm.

    Not really anywhere to lose weight on that ski. remove the oil tank, eat less McDonald burgers and only run half a tank of gas
