Jet ski wont start

Fuses in the electrical box?

repair it

You could have a sort circuit, somewhere

test voltage at the starter while pushing start button. its also possible that the factory ignition kill is activated, try holding up the lanyard button and repeatadly hit the start button if the alarm is engaged then you should hear the starter barely kick every couple of seconds so then just unlock it. and last and certainly the most common, starter solenoid, they go bad all the time. be sure to check your fuses first though.

Hello...could be you have water in your engine ,,,did it almost sink? Any way remove the spark plugs ASAP and see if you have water in your cylinders by hitting the start button ..Just as if you were trying to start it but leave the spark plugs out . If water comes flying out of the spark plug holes you now need to ,,what is called pickle youe engine . Water is horrible for the inside of the engine so lets see what happens when you do the above .If there is water crank it until it is no loger coming out and then fill the spark plug holes with oil ...any kind is fine and let it sit for a few hours then crank it again ,,,no spark plugs in it ! Then e me back for the final instructions ,,ok? Gelcoatpro @yahoo.com good luck! Pat

sounds like starter solenoid contacts are bad!

Check your ground wire, and also check to see if you have a fuse/fusible link that went out.

you need to put a new battery in it if that does not fix it you will have to replace the solenoid

If the teeter/totter needles are gummy or covered with moisture corrosion it could be the reason the machine is so hard to start. When storing the jet ski's syphon all the gas out and burn it in your car or truck. Even if you stabilize it it wont be good fuel in the spring. Your plastic tank will not rust so remove the fuel. You may be able to clean them up by running a tank of Chevron Techron through them. Before riding we charge are batteries and start are jet ski's on the trailer/lift before dropping in the lake. This saves the battery. It takes more juice to start the boat in the water.
