low rpm

So I have a 1997 Seadoo SPX that has been having top end RPM/Speed issues when in water. When out of water I can mash on the throttle and there does not seem like there is an issue, it revs and tops out with the signature 2-stroke sound at top end. When in the water, I have mild acceleration to...

I had my 96 Spx on the lake last weekend and it was running great for about 20 minutes, no trouble accelerating or maintaining speed at high rpms. I adjusted the trim a few times and it ran great for another 5 or so minutes and then the engine just died completely, no bogging, just off. It'd...

I actually have a boat but posting it here since it's the same engine as the ski's and most of you guys are in this sub-forum. Right after WOT (in 6200ft elevation lake at 68degF water) it goes to 8150rpm for a second but then drops to 6800 and stays there for my max RPM. My SC is producing...

Tony, Need your help... Took the boat out today... shes been running great all season. Got 500 yrds from the dock after launching and she cut out. Tried restarting a few times and it would start for 1-2 secs. then cut out. now she wont fire at all. Turns over fine, and she sounds like she...

Greetings, I just put my recently purchased 2012 Seadoo 155 Speedster in the water. Only 17 hours of use. It was not able to achieve over 5500 RPM and actually started being less during a 2-hour run. I would appreciate any thoughts on this...

Recently we've noticed that our 1996 Seadoo GTX has lost power on takeoff (and during hole shots). From memory, it seems like when we used to gun it to get on plane it would immediately reach ~7,000 RPM coming out of the hole. Nowadays, 9 times out of 10 it will start off at ~5,400 RPM then...

Hey all, I have a 1996 Seadoo GSX with the 787 Rotax, I just recently replaced the fuel lines from the crappy gray lines, cleaned out the fuel selector valve, changed the inline filter out (small filter before carb) and broke down the carbs to an extent. I didn't replace the pop of...

On my '03 GTX SC, I just replaced the pump (aluminum pump housing, new wear ring, bearings). I also replaced the impeller with the Solas recommended one for stock engines (Concord SR-CD 12/20). I also replaced the driveshaft, thru-hull floating hat, carbon seal, PTO bearing and bellow. The oil...

2001 Challenger with twin 717s. Last time on the water the left engine started losing power and wouldn't rev past 5000. On the trailer it has trouble starting. Once started it won't idle, only run with throttle part way up. After starting the hose, water starts squirting from the curved exhaust...

Hello and thanks in advance for any advice. I bought a 2000GTX RFI with the motor in boxes (appeared to be a seized crank but was a piece of ring caught in cylinder) so i purchased a BRP short block, installed and was on the water. The machine ran great with the exception of 12V low alarm...
