Over heating problem

[stmanser]

1994 Bombarider Seadoo 580CC.


We just changed the battery out and it fires right up now and will run perfectly fine out of the water, gets warm, we shut it off.

take it to the water.. runs fine for a few and then dies and it is a pain to get going again.

i am guessing it is over heating.

I spoke with scooper and he told me to take the top of the head off to get to the water passages and check for blockages.

Does anyone have this manual on PDF? I seem to be forbidden from the manuals page on here.

Anyone have any ideas at all?

I would have thought this would be a common enough problem on any jetski

or is it because i am new??

You’ve been told what to do… so do it.

If you are overheating… you have a plugged system. Pull the hoses… pull the head, and clean it out before you smoke your engine. It’s a very common problem for people who run in sandy water… or like to try to power off of the beach.

If you need a manual, look on the net… or join this BBS to get to that section. ($10/yr)

And no… it’s not that you are new… you didn’t get any responses because you posted your own answer in your first post.

I guess i was thinking that someone might have had this happen in the past, or other things to try and look at.

I was a member of another forum, and we offered our experiences all the time when someone had a question, or a comment.

I guess I was just hoping someone else would on here as well.

I will work on it, and hopefully figure it out.

Why do you think it's overheating? Does the beeper sound continuously?

No thats the thing that makes me think.

There are no buzzers sounding at all.

It will startup, and runs great for a little bit and then shuts down, and is a pain in the butt to get started again.

when it is cold again, it will crank and run fine, for a little while and then the cycle repeats.

The last time it was on the water, i was not around, so i dont know what exactly it did after i adjusted the idle and cleaned the carb. but everyone said it is doing the same thing as before, which is what i mentioned.

I have worked on cars for years, and there isnt anything i cannot handle, i just have never worked on a jet ski before. so i do know you need air, gas and spark, it has all of them, but wont stay running.

Overheating will not shut it down. Is the engine getting too hot to touch or are you just assuming it's overheating? I would try and fix the shutting down problem first. Then go after the overheating problem. Check your rotary valve clearance.

I am assuming it is getting too hot.. it has gas and oil and just shuts down.

I am afraid my jet ski knowledge is very small but i am mechanically inclined. i can fix about anything


what is the rotary valve.

What happens is this. It starts up, runs fine for a little bit, then after (maybe 15-30 mins) it stops running and is a pain in the butt to get started, if it starts at all.

I was not out the last time it was in the water, but i was out the time before that, which was last year. It had to be towed back to the dock. we tried checking the spark plugs on the dock. poured a little gas down the plug holes, and tried to fire, it would ignite, run until the cylinder was dead and then nothing. when the ski is cold it will fire right up

The rotary valve is the intake valve. It's between the intake manifold and the crankcase. The clearance should be .010" - .014".
