so today I was out on the lake with the boat and family and having a blast, then all of a sudden when we pulled into a cove, it sounded like the oil rings were grinding on the inside of the piston cylinder and the motor stalled out. We tried to fire it back up, it stalled out again, then...

The Problem: I purchased a 1990 SeaDoo SP - There were several issues that needed to be corrected just to get it to start. Now that its running it seems to only run while on the trailer, and Stalls when placed in the water. Work Performed: The fuel tank was removed and flushed out, the...

Hello all. Long time reader, but first time poster here. I have an emergency situation and would appreciate any and all input! We took our '98 Speedster to the lake for the weekend and had a blast. We decided to leave it tied up at the dock overnight, the first time ever, instead of...

Hey guys, I took on water today, about 1/3 full in the hull. I have been following the Shop manual for a Water-Flooded Engine (Section 02-04). (Please see the attachments) How exactly do I go about changing the crank case oil? The filler plug in the picture they show is not exactly...

First off Hi to everyone this is my first post, I recently purchased a running 1997 Seadoo SPX for £300 to do up as i have heard these are great ski's, I have previously owned a 1998 GTX 951 Limited 130hp bit heavy and more like a boat, So i sold it and brought a 1997 XP with the susspension...

Hi, If anybody has a complete Rotax 1503 SC IC engine for sale to suit a 2005 GTX Limited Edition Sea Doo Jet Ski - please post here..!! Thanks Shane.

I have a 05 or 06 RXT 4-Tec Supercharger Seadoo. It is Black and Green. I had some friends driving it, they forgot to take the small bag anchor off the Seadoo while having two people on it and pulling a skier. When they started driving I heard a loud "boom" sound but wasn't sure what it was...

I recently got some advice from a local mechanic and I just wanted to pass it along to ya'll and see if it was good/sound advice before I attempt it on my own ski... First off I have a Seadoo 97 GTS with a 717 engine... and I have noticed as of recently that the engine is not preforming as...

:confused:Hello. thanks for the great resource for seedoo info: I have a new 96 Speedster with the twin 718 cc Rotax engines, only 5 hours on engines and boat. running urine yellow oil in the injectors apparently very heavy mix by the smoke and oillyness of exhaust. Prior owner says it is...

Hello everyone, I'm new to boating and have a question about my boat. I recently bought a 95 seadoo speedster. I've had it out 5 times with no problems. Last weekend while on the river I idled out of a no wake zone and cranked on the throttle and both engines stayed at 3000 Rpm. It was...

Hi there, So in 2003 i purchased a 2003 seadoo speedster. Over the years of storage from being away the boat has just sat until 2010. I was trying to look for an owners manual somewhere so I could do the check ups and make sure everything is running fine. I have put it on the water 6 times this...

I have a 1998 Speedster. Yesterday while operating I started to get inconsistent revving of the port engine. Engines start with no problem. After warm up, rev both up to get to plane. Starboard engine goes to 5,500 RPM, port engine gets to 4,000 RPM and stays there. Then I get bursts of...

I'm looking to buy a 717 720 series Seadoo engine to put in my 99' Seadoo Speedster SK. If you have one or know where I could find a good deal on one, please let me know.

Hi, Does anyone know if an engine from a 1994 Seadoo Speedster will fit in my 1999 Seadoo Speedster SK? I'm looking at an engine on Ebay and I wanted to confirm that it will fit before I purchase it. Both engine sizes are the same (the 85hp model). The engine motor # from the 94' is...

To build off an earlier thread, my ski runs great at low RPM's. At about and over 3/8 throttle, the ski pops, at the same time the ski stops pushing. This lasts only 1 second and the ski continues as normal. This happens at random but on average ever 3 seconds or so, regardless of what the High...

Last season I blew the drvier side engine so I replaced the pistons, installed a carb rebuild kit, and cleaned and installed a RAVE rebuild kit. All parts were bought from SBT. I took it out last year when it was complete and it ran fine. I didn't winterize the boat this year...I know really...

Ever since I bought this ski, I have had issues with it. I have changed out the starter motor twice and been through a ton of batteries troubleshooting. Anyway...now that I got all that done, it only seems to run well at low RPM's, about half throttle. After that point, I can hear a popping...

Hi, I just bought a 2003 Sea Doo Islandia. The Boat runs fine except for the engine's master alarm will go off shortly after I start the engine. I have checked the battery and Alternator and those are fine. (I initially thought it was a battery thing). What else could it be? The engine...
