Seadoo Blown Head Gasket - Diagnosis

Here we have a 2006’ Seadoo RXT/RXP Rotax 4-TEC engine in which we show how we diagnose a blown head gasket .
This video is applicable over the whole 4-TEC range of PwC rotax engines .
Thanks for Watching
( blown head gasket replaced with oem - PwC good again )

Hi everyone, I’ve got a Sea-Doo 2008. I’ve got speakers on the side but one speaker doesn’t work. Does anyone know I can check if they’re not working properly thank you

Maybe just swop the one speaker that is not working with the other speaker that is working and check maybe it’s only a speaker . 🔈 🔊

I had picked up two identical, 2008 Sea-Doo GTX wake get skis. I was trying to do a complete once over with spark plugs, oil, oil filter, along with fresh battery and go from there.
The one Jetski oil was milky and antifreeze had bits of oil in it .
I’m linking it to being either a head gasket or oil/antifreeze intercooler failure.

What was that rattle sound upon start up

[@Redrockat]

All sounds normal , sometimes the jetpump steering nozzle may rattle as it has necessary play on it .

Great video! Maybe you can help me with a problem I'm having on a 2013 seadoo gti130se. It has over a 1000 hours and got an overheat alarm. Turns out it had oil in the coolant but no coolant in the oil. I pressure checked the oil cooler and it didn't leak, so I decided to have the head milled and replace the head gasket. After all that work, I took it out for a test run. It was surging and wouldn't stay above 5000 rpm. Gradually though it started running normally. I was periodically checking under the seat for any leaks and all seemed good until after about 30 min I got an overheat alarm. Once again, the coolant tank overflow hose was spewing oily water, but no signs of water in the coolant. Any ideas what the problem could be??
