93 SeaDoo GTX

Ok, So I finally got all the parts back on the ski last night and all of the epoxy was dry so time to do a sea trial... on the trailer. I backed it down and cranked it up (First time cranking it in the water since I bought it) and the idle keeps running up and down from the 1500 it is supposed to be at up to 3000+ and then it idles back down. I gave it throttle, let it bcome back down and it does the same thing. I ran it for about 5 minutes and it never stopped. Any ideas?
Thanks,

Re: Funny (not really) Idle

maybe a little lean on one of the carbs?? Try opening up the lows a tad.. How does it run on dry land??

Hey Dan,
I know I normally sound like an expert and all...lol. But I am not sure where and what the "lows" are. I am assuming they are adjustments on the carbs. It runs the same way on land except more RPM's because of no resistance. The first time that I cranked it up 2 months ago, it ran fine and steady. Since then, nothing has been touched on the engine. I did pull the oil and fuel tanks out and cleaned them but that is about it except for pump work.

yes sir, on the carbs there are 2 adjuster screws (besides the idle). the one with a "T" handle on it is your lows. they are a pain to get to, and you will probably need to remove the airbox.

You could have old gas in the carbs, causing issues as well.

Is there one on each carb?
