hey guys, new to this forum, saw some helpful people answering other queries so i figured id post mine on here, maybe someone has some advice....my '94 GTS (which has been in storage for the majority of its life, has less than 25 hours on it total) has recently been taken out of storage and back on the water. It was running awesome until we brought it in for an oil change. Then it started labouring. when you go full throttle, the engine revs like its trying to get over a bump but cant (if you know what i mean!?). When you hold the throttle down all the way, it goes maybe half the speed it normally should. We brought it in to a dealer and they said we needed our carb cleaned, so we got it done, but today we threw it in the water to test it out and its worse than it was before! this ski was running fine when we first set it up with new fluids and sparkplugs, but then we brought it in for a service and a carb clean and now it just keeps revving as if its starving for gas? I dont know what else to do and i dont want to keep getting charged by these dealers (who have done nothing but make it worse thus far), so any ideas at all? i would really appreciate the help, and id be happy to provide any additional information needed. Thanks in advance to those with the knowledge i wish i had!

#13...

before doin anything, do compression test. If over 100psi in each cylinder, but not off by 10% of your numbers, then motors' good.
If you have the "grey" fuel lines, than I suggest you replace them with 1/4in black fuel line from any auto parts store. If grey lines are present, might need to clean/replace the fuel selector valve, along with re-check'n the external filter for junk.
If both these "ideas" are good, then "UNPLUG" the red wire from this diagram, #13, then with a "FULLY" charged battery, go try again...

BTW...does the ski rev high, but not move, or its run'n/throttle'n like crap?
 
thanks alot for the quick reply man....first off, my tech skills with seadoo's are minimal, so i dont really know how to go about doing a compression test. Second, i think the fuel lines are grey (the ski is 100% stock), but they seem out of the way and difficult to replace...
and the ski does run, like you said its running/throttling like crap...it goes about a third of the speed it should at full throttle...

Aint, the best, but will work. Remove the spark plugs, put plug wires on the grounding post (orange thing mounted on engine) and install hose/fitting to one side of motor, and hit buttton for 8-10 seconds, check the read'n on gauge, and do it again. You want to do each cylinder 3 times, to get average reading.
Problem with grey fuel lines, is they corrode internally, so even if you had the carbs done, but fuel lines are corroding, then all that crap IS back inside the carb again, starv'n the motor for fuel....
Anytime, bro...:cheers:
 
awesome, im just about to order one thanks again....in regards to the fuel lines....how difficult is it to replace them myself? im a DIY man, and im happy to take on a challenge but as i previously mentioned, my seadoo knowledge is minimal. If it is a reasonable task to take on, how long do you think it would take and where could i find a guide or something to walk me through it? if its not a reasonable task, then how much do you think i should be charged to get them changed? and if you say that the carb has all the crap in it again, does that mean i need to get them recleaned????
thanks for your help, i really appreciate this..
 
ur a DIY guy, so..quite ask'n how long it takes..blah, blah, and JUST DO IT...:rofl:
Nah, stud...get about 20-25 feet of 1/4in fuel hose (.25ft) and 20-30 stain steel hose clamps, to go with it. Remove one atta time, and replace it, with the new hose...:cheers:
