My Yamaha Jet Ski 750, turned over Bro.. my Jet Ski, Yamaha 750, turned over and after that.. I pulled out of the water took the spark plugs out, put DW40 in the cylinders and nothing happened.. the e

sounds like you hydro locked it and possibly blew out a reed in your engine intake or worse, you may have bent a crank rod. But before you go tearing it apart make sure all the water is out of motor and theres none in the fuel tank then put in a new set of plugs and see what happens,

Jetski losses drive sometimes, engine revs high

There is every chance you have sucked up something into the jet intake.Move the ski back on the trailer without unhooking the front winch.(so it wont fall on to you).Get a torch and look up into the jet intake.Something will be up in there.An old ski rope,plastic bags,a big clump of weed.What its doing is letting the impeller/propeller cavitate with a heap of air and disturbing the water flow.Hope this helps

Check the engine compression with a compression tester. It should be over 100psi,also check for hot blue spark on plugs,if not blue ignition problem.Weak Spark,but if blue and wont fire with ether the rings maybe worn,and compression to low...Best of luck to you!!!!
