300/440/550 Aftermarket Parts?

[WJLarson14]

So i just got my first jet ski and it is a 1985 kawasaki js550. it is all stock and i was wondering what aftermarket parts i should put on it. i don't want to mess with the motor so i wanted to know what aftermarket parts i should get. i was thinking like the impeller, ride plate, intake grate, etc. which one or something else should i get to make it better.

i would start with parts like ride plate and intake grate, then move on to pipe carb and impeller when its needed

don't sink a ton of money into the 550's unless you are looking to keep it forever. But as always, pipe and prop are a must along with a head eventually, or just get yours milled.
