Sea doo fish pro 22 wont start

[Lakey121]

Pulled my ski out after a while of no use and tried to start it up.
Keep in mind it only has 30hrs
Solenoid click and starter engages but won’t turn over engine.
I tried a jump pack and same issue.
I pulled out the spark plugs and it cranks over fine just slowly.
Suspect starter motor?

Probably not the starter w/ only 30 hours on it. Probably low batter from sitting. Pull the battery and have it tested.

OBTW. Never jump start a Sea-Doo; see your warnings in your manual. Many have tried and fried their ECUs.
