Hey everyone recently bought a 2002 rx di as an upgrade to a prior ski but on the last ride of the year the vts was stuck in the up position and I was not able to adjust it. It would just click when trying to put it down and make no noise at all when trying to move it up. I removed the vts motor...

I’ve been researching oils and besides the Seadoo brand I’m not sure what to get. I know I’m supposed to get a BOMBARDIER ROtax SYNTHETIC 2-Cycle Air-Cooled Engine Oil Low ash thats certified API TC and to NOT use tc-w3. Everything I find on google is Tc-w3 or outboard oils. Can someone...

Have a 1996 GTI I've rebuilt alot on. I've replaced the buzzer and start switch with high quality options from osdparts.com. I also replaced the info gauge from a reseller on ebay. All the multifunctions of the gauge work. I rebuilt the fuel baffle so gas level would show properly. Temperature...

Hello, everyone! So, after many days of searching the forum, reading on restorations, and wondering how to go about my two “problems”, I joined the forum. The reason for joining and searching is that I recently acquired two semi-neglected Sea Doos for free. One is a 1992 SPi 580 white engine...

Bought 2 PWC for cheap, not running as they had been sitting for 12 years. I have since rebuilt the carbs, ran new fuel lines, changed spark plugs, re-covered seats, and cleaned em. That's it. They both run pretty damn good, wish I had seen the carb rebuild sticky here before hand but things...

Im posting for help with a seadoo I'm working on for a friend. He dropped off a 1995 seadoo gtx. He rebuilt the motor and every thing worked fine til one day it cut off on him so he thought it was the fuel system. Asked me to go through it and clean it all, which I did. Still didn't help. Next...
