    03 185hp 4tec cranks but wont fire over

    Have a 2003 seadoo gtx 185. Low compression and would like to perform a leak down test, any tips on doing so??. Its not starting but is turning over. Getting fuel and spark. Compression is 60, 75 and 80ish. Was running good on water, then shut off when I came to idle. Over heat light came on with long Beep and wouldn't start. Was only running for 10 min and didn't let it warm up. It was towed and number 3 cyl had water in it so I suspect hydro locked from towing too fast. There is no violent missing. Two normal beeps at start up now. Starter was replace, Oil looks good. Suspecting a bent valves but would like help from the point its at now. 118 hours and sc has been rebuilt. Any legit ideas on diagnosing further. I was thinking leakdown test. Oh and violent level is good and its green with no oil in it. Oil is golden Not milky.

    If dropped valve would the piston or head be damaged you think?

    Doesn't matter, low compression, pull the head. Look at vavles. There should be something obvious when you pull the head.
