Could it be a clooged carb?
I bought it a few months ago so i dont know if I have thoose grey fuel lines or not. How do I know if I have them?
Seadoo GTX 2001 951cc carb engine.
Update:
I have now changed all the grey fuel lines. It took me about 1,5 hour or so. more
at he beginning of the thread. You were asked about the gray fuel hoses. do you have them? if you do, replace them. they are known to decay, and plug up the carbs.
For the RAVE's, take one apart at a time incase you forget how they go back together. Take the metal clip off, the red/black cap off. Take the air line off, remove the 2 allen screws and remove it. Clean the guillotine with carb cleaner and a brass wire brush or brass scraper. make sure it is brass so it is a softer metal then the valve and does not scratch it up. Also unscrew the black cap on top of the bellow, pull off the big spring. Wipe the inside of the bellow clean. re-assemble and install back into the ski, repeat the process for the other valve. let us know how bad they were, if they have alot of carbon build up it was probably the problem. FYI: these should be cleaned at least once a year, twice isnt bad if you ride alot, once in spring and once mid-season more
On another thread, you just mentioned that a GTX only goes low 50's for top spped. My 2000 GTX says it goes 65MPH.
Now, I know what you're going to say. speedometers on the ski are not accurate.
Are they really this far off? Sure feels like I'm going pretty darn fast..
You are dreaming if you think adding 20 HP will net 4 mph with the additional weight of a 951 powered GTX.
The average stock XPL will run about 61.5 mph. But there is a huge difference in the design and weight of the two boats.

After we receive your cylinders, we will inspect them and determine what oversize pistons it will take to make the cylinders straight , then bore your cylinders on a boring bar, final sized with a rigid hone. The ports are chamfered in a 3 stage process to ease the rings back in, including a final hone to extend engine life and improved performance.
Resleeve your Sea Doo 947, 951 back to standard bore '98 and newer carb models or DI. here
After making payment with buy it now button, ship your cylinders with a copy of receipt, contact phone #, return shipping address and any special requests.
Any used watercraft is a crapshoot because you cannot see rust that may be on the crankshaft bearings, but an experenced ear can usually detect knocks and rattles, and even a motor with bad compression if it is bad enough. Not to say a compression guage is not mandatory when checking out a used watercaft. [links]
I'm not sure that I would classify a 947 "ocean reliable" if you are used to the very good reliabily of some of the Yamaha and Kawasaki models from the two stroke era, but even both of those companies built a model or two that is also shaky at best anytime you are using them in salt or fresh water.

I have seen units with 300 plus hours on them. But that is usually not the case with most owners, as like the bad horse owner, they put them away hot and wet. Then, do not loosen the seat to ventilate, and cannot even tell you what fogging oil is, or what it is used for on a watercraft. Some have no idea where there flushing port is located on their watercraft, and if they find it and connect a garden hose to it, they do not know that the engine must be running and that they need to shut off the water before they shut off the motor.
I just replaced two Yamaha 1200 motors with under 50 hours on them because the buyer of these two perfect used Yamaha's had no clue about not running water through them with the engine off before he put them away for the winter last year. I removed the sparkplugs, noticed alot of corrosion on them and stuck a screwdriver into the sparkplug holes and it came out soaking wet with brown water on it. The other motor was the same, as full of water as he could possibly get it. [links]
If you keep water out of the 947 engine and do not allow the carb internal filters to become clogged up, it can be very reliable. Even moreso if fogged after each outing before storage, even if it is just for a few days. It should get fogged well after every outing, especially if ridden in salt waters.more
You might look into a fourstroke if reliabilty is paramount because you ride alone. Some sort of ship to shore communications is a must if you ride offshore very far, even if it is just a cell phone, provided you can get a cell signal. If not, buy a handheld HI Freq radio or EPROM device and something to attract a passing boat or ship. It can get very lonely out there drifting further and further away from safety. Weather out there can completely change in a matter of minutes and go from calm seas to huge rollers with rain and wind or just get too foggy to see anything at all.
