LRV DI overheating please help!

[ws6power]

Hey guys I've always had boats, but I'm still pretty new to seadoo and need a little help. The last couple times I've had my LRV out it runs good but if I run it WOT for more than a few seconds I get an overheat alarm. I can run around at 3/4 throttle for a long time and won't get an alarm, but as soon as I start riding it hard I get the alarm. It never stopped pissing and I felt the stream when I got the alarm and It was pretty warm, but not what I would call hot. I popped the seat off right after the alarm and could touch the head and exhaust. Both were warm but again not what I would call really hot. I can't find any thing blocking the pump and like I said it's still pissing. Could I still have a blockage some where else? Where all should I check for water flow when running it on the hose? I can see water coming out the pisser, exhaust and the port to the right of the pump. Where else should water come from when flushing? I see 2 small tubes inside the jet should waater come out of these also? Thanks

Change your temp sensor

You think it could be that simple? I think I have more than one temp sensor and I'm trying not to just start throwing parts at it. I've made that mistake before.

clean the raves, and install new plugs....

If the engine is physically "not hot." The pisser is working good. The rubber exhaust hose is not melting and you can touch the engine block with your hand and not get burnt, I would say that the temp sensor is not working.....

no - that is where the pump sucks in water to make your bailers work...good luck

Thanks for the responses guys. I'll do a tune up this week end with new plugs, oil and gas filters and see if that helps. I'll also see about cleaning the raves and finding where my temp sensors are. Thanks

 

[greyrider]

temp sensor is directly between the plugs with wire plugged onto it

 

[ws6power]

isn't there one for the exhaust also?

 

[greyrider]

yes - have to look at mine again for exact location tonight

 

[ws6power]

that would be a big help thanks a lot.
