power loss

I bought this boat about a month ago. Upon doing some research I keep seeing similar issues with carbureted engines, but mine is a 4-tec efi. Start/ stop is flawless, it runs fine for a while, even at speed and planing, but usually about 40 minutes in it starts to sputter and die. This happens...

Hey, So, I try and keep this short but I am a bit baffled by this machine. We purchased this 96 GTX a month ago for a good price. It fired great out of the water, had to wait a week before putting it on the water and battery was weak and didn't want to start put a fresh battery in and it...

Hey everyone, having some issues with one of my 2000 seadoo gti’s. So in the past when you accelerate, the jet ski would go and then lose power for a second and then “grab” and take off normal. We took it tubing one day and then the jet ski wouldn’t run at all later in that same day. Currently...

So I'm at a bit of a loss for what is wrong with my jetski. I have a 2005 Seadoo RXT. I put it in the water about a week ago after being outside all winter in Minnesota which it was winterized for. However, when I went to drive it that day and also the next weekend, It wasn't able to reach the...

2008 RXT-X supercharged. Had the SC rebuilt and replaced just barely, and the seadoo isn't running well. It will start/idle just fine, but when you drive it, it acts like the learner's key is in or something...feels like there is less power and not supercharged. Then when we drive it harder...

Sea doc GTX 155hk 2002 420 hrs hi! two days ago I was out all day driving with my sea doo (worth mentioning is that i had some big jumps) and everything was working fine as usual, left it behind the boat over the night as usual and the day after i went for another run. This time i run in high...

Hi All, looking for suggestions. I have a 2000 Sea Doo GTI. I am the original owner. Recently when we go to take a ride it is very sluggish for about the first 15 to 20 minutes of running. I'd say it doesn't exceed 2000 rpm and sounds like its struggling. Tis is at full throttle. After a...

2005 RXT, supercharged, 215hp, 130 hours. Engine surges back and forth between having some power and full power. It surges back and forth about every one to two seconds. It responds to the throttle, but never has full, steady power. What should I check first? Then what? After that, what...

Hey Everyone.... I'm a Newbie here. I will apologize in advance for redundant questions. I have searched the "Fuel - Bog - Power" tag words and have narrowed my issue down to about 10 possible causes. Please help...... I have recently purchased this '95 SPI. Initially, I rebuilt the jet...

Having issues with one engine seems to not have full power with take off. Can't pull up skier. Once boat levels off then ok. We have owned this from the start. Never have had any issues. It is almost like there are weeds in the impeller but everything checks out. Thanks for any help new to...

My 98 GSX Limited has been in and out of the shop lately. The latest problem it has is really odd. With the seat on, it will top out at 35-40MPH. The motor sounds fine, the ski just doesn't get up to top speed. However, when I take the seat off it tops out at 65MPH. The best I can determine...

Hello, I was wondering if i can get someones 2 cents on an issue im having since people on this forum seem to know what there talking about. i have a 98 sportster 1800 with the twin 717 motors. one engine is losing power. the rpms were at 7000 rpm at first and its slowly decreasing, now its at...

I have a brand new GTX 255 is Limited. Had roughly 2 hours on it when there was a sudden loss of power (down to 4k RPM Max). It appears the Supercharger hose blew off from the pressure (engine cannot consume what the impeller seems to be pushing out causing the hose to blow off the motor)...

The problem with my 1990 seadoo SP is that, while the engine is seemingly running at a perfectly normal idle speed and will perform perfectly well after warmed up for a sufficient amount of time, the last time that it was in use, suddenly it ceased any propulsion. the engine still runs fine...

So I've got a 98 XP LTD that's giving me a fit:ack:. After about 6 hours in the water my ski suddenly won't go over 3500-4000 rpm and smokes a lot. I checked the compression and got 150 in front cylinder and 170 on back. No water in cylinders either. Thing that's really throwing me is that...

I recentley rebuilt the carbs, changed the fuel lines, cleaned the selector switch and the in line fuel filter. My wave runner runs better until i get to 33 mph once it gets there it just cuts out then once it drops to 20mph it takes off again, any suggestions will help thanks

it feels like there is a shear pin busted somewhere, or a clutch is slipping somewhere, because it jumps up, then levels out but will not get up on plane or go faster than 10. I rebuilt the motor, and have never run the boat... it was a rental. it's a '94 Seadoo explorer with a 583. Is there a...
