Hi there I'm new to the forum. I have a 2003 seadoo 4tec that crank but does not start some times. When I jump the starter solenoid it starts. I replaced the solenoid but does the same think. I checked the voltage on the starter and when I crank I only get 10 v on it while cranking. I have checked resistance on all the cables going to the solenoid and all is fine. Do anybody have any ideas what else I can check. Also I took the battery to get checked out for the crank amps and it was fine.
