I have a ’96 Seadoo GSX that runs great except; it won’t always reach top speed/rpm. To reach top speed/RPM is sometimes tough.
Here’s what I have to do to reach maximum speed/RPM.
1. Simply pin-it and it reaches 6,000+ RPMs (this works less than ~ 20% of the time)
2. Yo-yo the throttle a few times and it reaches 6,000+ RPMs (this works about 20-30% of the time)
3. (or) Jump a wake or bounce hard while pinning the throttle (this works EVERY time 100%)
* Otherwise it hovers around 4,800 RPM and acts like it wants to go faster.
Here’s the stuff you need to know.
I bought the craft with a blown engine. I’m a retired aircraft mechanic. I rebuilt it but let it sit in the garage a few years before I gained more interest.
· Motor is a fresh rebuild (less than 8-10 hours) punched1st over. New crank, bores, pistons, rings & bearings. Crankcase pressure tested.
· New Fuel lines replaced & Fuel Petcock cleaned @ 0 hours + carb refurbish
· Fresh gas (drained the tank and refilled)
· New plugs (changed several times)
· Compression (MAG 155 psi, PTO 154 psi)
· Completely rebuilt both carbs (soaked for several hours in Berryman Chem-Dip and blow out with air and cleared with wire. All brand new gaskets & rubber (except needles and main – they look perfect) pop-off set.
· Cleaned RAVE Valves (look brand new)
· Replaced RAVE Bellows (green), gaskets and o-rings. Added zip-locs to bottom of bellows
· New pump wear ring replaced (less than 4 hours)
I’m starting to think that it’s the regulator on the waterboxor a waterbox baffle issue. I’m better at Polaris PWC issues than Seadoo.
Help a brother out.
