I have a 1997 seadoo that i had snagged for a low price since it had sat for two years and slowly been trying to fix it. After getting it to start i have ran into 2 problems. The first problem is after about 30 seconds of idling fine it starts to idle poorly with a pretty bad vibration.
The second problem which im assuming may be causing the first problem is it doesnt seem to be getting enough fuel. I can trot along with about 1/4-1/2 throttle but when i go 3/4 or full the ski will get up and go for about 2-4 seconds then bogs down but it doesnt die. If i continue to hold the throttle after it boggs down it starts to go back and forth from getting up and go to bogging down over and over again. A reason i believe it is a fuel problem is because if i pull the choke slightly out i can get the ski to stay at full speed without any problem. I have taken the carb apart and replaced all the peices and parts inside and cleaned the carb itself with carb cleaner, and re adjusted the jets based on manufacture specs. I am aware of the grey fuel lines and i have replaced them but that is the only fuel system related parts i have replaced. The engine itself is good, with relatively good compression. I was curious if my guess on it being the fuel system would be right and what components I should start looking at first rather than just starting to take things apart.
One thing i have noticed is when i trailered the ski i took off the seat and ran it at full throttle and (correct me if im wrong as this is the first watercraft i have ever worked on) it looked almost as if it wasnt pulling much fuel out into the filter (see through). I observed when at full throttle quite alot of bubbling coming into the filter with the fuel. From what i saw aswell it didn't quite look like it was pulling in a substantial amount of fuel, or at least to me it didnt look like enough to maintain a relatively fast speed.
One last thing that may be irrelevant but the ski, mostly out of water, likes to blow alot of white smoke. I have taken the oil Injection cover off and the markings are lined up and i believe the throttle cable is tight enough.
