    Rotary valve question

    Hello, I got a 1995 spx I'm replacing the crank seals on. The rotary valve is between .010 and .012 thick. It won't fit the .012 feeler gauge in. I'm wondering why this barely is in spec. Because it seems like the gap would thicken if it was out of spec. I'm thinking of replacing the rotary...

I'm wondering if anyone sells an aftermarket one...

    Bottom end rebuild questions-657x

    I am currently removing my engine to replace a leaky MAG seal. I'm likely going to change the PTO seal. I want some pointers on how to inspect the crank center seals. I have oil in the bottom of the PTO (it shoots a lot of oil out the spark plug hole when turning over). Idk if it's the crank...

    New to PWC's in south Louisiana

    I'm from the Lafayette/BR area, and I am restoring my 1995 SPX. I'm looking for people to help me finish my restoration(most importantly align the engine because I don't have the tool) and to ride with once I'm done re-doing my engine. I'm the only one of my friends with a PWC(or more...

    oil issue

    Hello fellow water bike owners, I recently came into an issue(s) on my 1995 sea doo spx with the 657x engine. I acquired this ski in no-start condition. I did a full fuel system rebuild(carb rebuild, fuel line replacement, fuel baffle replacement) since it had a fuel issue, and it started and I...
