Hi all, I just picked up a 94 seadoo SP from a client. It’s been sitting for god knows how long. He inherited it with a lake house, and since he planned to sell the house and wanted nothing to do with the SP he offered it to me for free if I could get it off the property for him. Upon getting it home, I opened it up, and it looks complete. I put a battery in and tried to crank, no surprise, it didn’t.. I pulled the electrical box out and tested all solenoid posts 12v at battery, y/r wire, and b/w wire. I jumped across with a screwdriver, and the started clunked but didn’t turn the motor. After a couple tries it turned a little, but very slow. I checked the cables and all look ok, as well as the connections. I pulled the plugs and tried to manually turn the output shaft but there’s a fair amount of oil and grease on it and I’m unable to. It did turn a bit from the starter so I don’t think anything is seized up. I want to crank it so I can check the compression before I put any money into it. The battery I’m using isn’t new so I’m concerned it not pushing enough amps. Anyone else have any ideas?
