Thread: New Guy Here!

Hey guy's just wanted to say hi.. I'm working on pushing my Seadoo Speedster 200 to 70 + MPH from a stock speed of 57.7 lets hope it works!!!!!

Hi Somefun,

Welcome to the site!

Sounds like your a world pioneer for the Seadoo Speedster

We have a few of them floating around Australia and they are getting more popular........Most mods done to an RXP motor should be able to be done to the Speedster. (Engine)

If you need any help just let us know......

Hi guys, That Speedster-Project sounds like fun, love that boat...do you have any more pic's of the work/boat?. How big are the IC's you use, bigger than the Riva Powercooler.? What is the RRacing SC overdrive gearset..? Is it 185hp engines..?

I'm working on a 06' Sportster. We have put on a full Riva Racing S3 kit, a bigger IC, and working on a bigger Exhaust, with mod. waterbox and 3" Rear exhaust.
We hope to push this boat to 70mph to but we dont know what impeller/pitch to use, any idears.? thanks

Thanks... Yeah I really haven't seen anyone do very much with the boats... But it's going real well. The boat stock ran a GPS of 57.6 and now its running 67.8... Since then I've added but not tried yet. Riva stage III chargers, over drive gears, 19/20's Solas and ceramic SC bearings. She should hit low 70's I HOPE....

Here are some photo's they don't do it justice but you get the idea....

I was thinking of it but the wife would go nuts if it was too loud... It's killing me because I would like to gut the cans and let here rip!! Do you think there is any gain's to be had? And also would it be way loud?

Hi Somefun,

If you gut the water box it will be loud!!!!! Gains will be minimal until you get the Engines up around 300hp... Their are plenty of ways to make Hp without creating a noisy Monster....

P.S. Love the set up mate Great Instal

Thanks US Perf... Thats what I was thinking. Right now it's a sleeper you would have no idea it goes as well as it does. I think that by spring time I'll have done just about everything i can with still keeping it reliable... The one thing I'm thinking of doing is the Riva valve springs and retainers for safer RPM's...
