Hi All,
I've recently bought a second hand jetkski (first time owner!) - 2006 Kawasaki STX-16F. The family I bought it from said it hadn't been used/started in a few years.
First time I put it in the water, it overheated after about 20-25 minutes (used mostly at full capacity). It then overheated intermittently after that (after allowing some time to cool). Revs also ran high - going at about 10kms/hr without touching the throttle.
Im new to the boating scene and fairly inexperienced. A few hours in, I accidentally ran onto a mud bank. I killed the engine straight away, but was in very shallow water. Managed to get the jetski into deeper water, but upon re-starting the engine, there was smoke coming out of the motor and pisser. It also overheated straight away, but not for long (assume once mud was flushed out). The smoke also subsided shortly after. I took it back slowly with no further issues.
I then took it to a jetski mechanic and after a quick once-over and undoing a pipe that leaked sand, he told me the water pipes need to be cleared. I also told him about the overheating issue prior to running onto the bank, as well as the high revs. Next day, he told me that all the pipes were cleaned and the jetski was running perfectly. However, when he went to put the revs back to normal the ski overheated on idle. He suggested the only possible cause for this is a crack in the cylinder head, explaining that the water running through on idle is being evaporated by the engine and therefore not cooling. But by running on higher revs, it allows more water through. Quoted to repair in excess of $4000.
I took the jetski out the day he gave it back and it didn't overheat once. Used at moderate to high capacity for about 3 hours. Revs were still high (approx 5-6kms/hr) as he said he wasn't able to reduce to idle for above reasons, but no overheating.
The jetski however, full of water when I pulled it out of the water and released the bungs. I'd guess about 15L of water came out. The front storage section (where you keep things from getting wet) was also 3/4 full of water - im lucky it didnt sink! Ive called the mechanic and he is going to look over it again, im guessing something wasnt replaced correctly after cleaning the pipes! Not sure if this would have helped with the cooling and maybe the reason for it not overheating all day? But she otherwise ran perfectly.
Anyway, my question is... Is there anything else that it could be aside from a crack in the cylinder head? Really hoping its not a $4000 repair job
Any help/thoughts/advice is greatly appreciated as im not familiar with this stuff at all!
Thanks!
