Ski won't start

[midwestblues]

I tried to get my ski fired up after a winter in storage. I charged up the battery and when I go to start the ski, it would only turn over partially and that's it. I had the battery tested and they said it is 100%. Do I just need a new battery or could the motor be freezing up or the prop shaft binding? Any suggestions welcome. The ski is on an island and it is about a 10 mile water tow to the nearest repair place. Thanks

Pull the spark plugs out and see if you can grab the driveshaft couplers and spin it over by hand.
If that works I'd try a known good battery.

I'm with b.lee. Pull your plugs, then push the starter again and see how she turns.

You may have a bad starter, a bad battery, or someone broke in and milled your head to 380 psi compression (less likely).

I would also check all battery cables/connections going to ebox and to starter. Sometimes corrosion builds on negative battery cable on starter end.

id start with turning it over by hand no plugs. rusty cylinders will cause a no crank
