Bought a seadoo RXDI that had a recent rebuild by previous owner.

First day out in the lake it randomly cut out, 5mins later it went fine.
Day two same thing happened but then worked fine for couple of hours.

Today cut out after a run of 25mins at about 3000rpm.
No wont start...

The JetSki will only turn over a click. I have checked the intake, not blocked, I've check the PTO and it does rotate each click (should I be able to move this easily).

When I take out the spark plugs it turns over but struggles with just the pressure of my thumb over the plug hole.

I'm going along the 'Hydraulically locked air compressor or seized jet pump as I don't want to think about the seized engine route! Any ideas how I can check the air compressor or jet pump? Or any other ideas.

Many thanks.

OR direct fuel problems - am I going along the right lines.....

Not enough compression to turn over the engine (or push my thumb out of the way) direct fuel or the air compressor?



(Engine will turn over a couple of clicks now but not much...)
