2000 seadoo is overheating

[cfirefightera]

Hey everyone I'm new here and I'm new to working on my own seadoo so I need ur help. I didn't really know where to put this so I'm sorry of its not I'm the right area.. Anyway I have a 2000 Seadoo XP. I haven't had a chance to ride it In the last 2 years and this year I got it out un-winterized new plugs fresh gas oil change new battery checked all hoses and wires everything seemed fine. Took it to the lake and rode it about 5 mins then the high temperature alarm came on. Put it back on trailer and it was super hot and smoking in engine compartment. When I got it home I unhooked most of the hoses and blew air thru them to make sure they weren't clogged then hooked Waterhouse and flushed it and it ran fine and stayed cool. Now I'm stuck and I need you guys help. What do I check/change now???

You should provide your model.

Who winterized it, maybe they left an hose pincher on one of the cooling lines?

Cooling lines may be misrouted, from or during the winterization procedure?

Running on hose, water is back-flushing, so the circumstances are not the same as riding in the water. Also, engine load is near zero out of water.

I say double check your hose routing by referencing the service manual for your ski.

How about your tell-tale outlets, were they flowing water during your ride?

Temp alarm sensor is mounted on cylinder head on mine. If same, your cylinder(and maybe other parts) wasn't receiving proper cooling.

I mentioned it's a 2000 seadoo XP. I had it winterized by a big boat shop in the area. I'll check the routing of the lines in the AM. And the outlets were not flowing any water at all while I was riding it at the lake. They did flow water while I was back flushing.

Oh yes, sorry I see you did specify the model. I must be tired and should hit the sack.

Anyway, I'm guessing you have the 951 engine in your ski, if so the cooling water enters the engine at the top of the head, here's a link to the 951 in a Sportster boat, maybe this will help, it's quite similar except I believe you have two seperate tell-tale outlets as opposed to teeing them into one:

That link doesn't work so well, you have to select "cooling system" on the left menu.

BTW, I always make sure the customer's boat won't burn up if he doesn't de-winterize and just pops his boat in the water, the only exception is if the boat is stored in the water it's not possible to isolate the antifreeze absent a shutoff valve.

If damaged, and based on the terms of your contract, your boat dealership might accept some responsibility?
