My 97 gp760 did this. I checked almost everything. Replace or clean your plugs, then run carb cleaner through your fuel filter both ways, and then spray carb cleaner into the fuel line from the fuel filter to the carbs. Run 10 minutes, more carb cleaner into the fuel line, and run it 15 more minutes. Then zip tie fuel lines at the fuel filter. I figure there was trash or buildup in the carb. Its easier than rebuilding the carb. Try it. Daniel at the MEXPIPE Pto Escondido Oaxaca.

It Runs but has very little power,quits often,if you give it to much throttle it bogs down


Robert, First try new plugs, check fuel filter, sounds like it could be carburetor/injector issue, dirt,plugged jet, etc. Remove and clean/rebuild carb./injector.
Check the attached links,instruction and guides, Good luck

Yamaha xl1200 waverunner losses power after it is warmed up.


Hi, most likely cause and the easiest to check is exhaust leaking in the engine compartment. Run it without the seat fitted for the same time frame and if it fixes your problem you are looking for an exhaust leak. Regards Phil.

Ttr90 bogs down at high rpms


I have a ttr 90 that idles well but bogs down at full throttle. Carb is clean and has new pilot and main jets. Seems to run slightly better with intake off. Which leads me to believe the mixture is rich. No adjustment on carb. Stumped?

My '94 yamaha waverunner 3 runs great for the first 30 minutes. After that it will run fine at idle and just above but the rest of the throttle it just bogs, like it is running out of gas or has some kind...


Could be a bad temp sensor. The bog is a rev limiter to keep engine from running full throtle when hot or when there is another problem. You can bypass the temp sensor and see if that takes care of problem. The parts about 100.00. I disconnected mine a now run a temp gauge which I mounted on the right side just above oil gauge.

I have a 2002 yamaha waverunner xlt 1200. it will idle fine but when you try to give it gas it bogs down like its not getting fuel.


hate to break it to you. carbs need to be rebuilt. the new fuel doesnt bode well for the carbs, clogs a really small filter and jets in the carbs
just had it done for the second time for a cost of $550/each time

Waverunner bogs down on acceleration


Our 1996 waverunner has been running great until this weekend. It seems to bog down after 3 minutes of running at full speed. If you keep it at 3/4 speed no problem, it runs steady. Tried carb cleaner but it still runs the same....What repairs are we looking at. thanks.....
