99 spx cuts out when wot

[Dbrinson]

I have a 99 seadoo spx with the 787 in it. I can get it to accelerate but. When I get at wide open throttle it does accelerate right. I have two of these and the other runs great. This is how I know I having some kind of problem. Also it will come in to it and start to accelerate in burst at wot but will not maintain for more than a few seconds I say it will run about 20-25mph. They have been stored for he winter season and I am trying to determine if it is an adjustment a
In the throttle or tune up or what. I did put about a 1/4 tank of fresh fuel to top them off and debated on if I could run any addititive or something to help degum the carb. I work as a auto mechanic and new to these things also have the clymer shop manual to resource thanks for any help or respoms if someone has had the same problem.

first pull the caps off the RAVEs and see if a diaphram has popped off the top.

Outside of that, Sounds like the typical fuel system problems; if you have grey tempo lines change them, clean the selector switch and fuel/water seperator, rebuild the carbs with genuine kits and needles and seats.

Ive got a 1997 and last year it was time for a stator and a coil. Had lots of spark but still had carb issues.. Ill be looking at that soon.

In '97 Seadoo came out with slotted raves that apparently cured that problem.

Ok I will try cleaning the raves and I am gonna go ahead and tune up needs it anyways does anybody have a clue on much the carb kit and thE lines run and should I get clear lines

 

[Minnetonka4me]

Carb kits are $50ea, needles and seats $20 ea, 20 1/4" fuel line $30, 3 feet 5/32" oil line $5

Do not get see thru lines. They cant handle ethanol and fuel additives.

Ok got it on the wTer and noobed it by forgetting bilge plugs so some set back got it cleared and running hoping to test again soon

Ok after weeks of waiting and storms and more storms I finally get the ski back out. I replaced the fuel lines and cleaned the raves and replaced the spark plugs The thin ran like a dream. Maybe all the water flooding the engine cleaned something out but doubt that thanks for all the help and advise
