i took the ski to a marine repair shop and they told me that i had a seized crankshaft. they quoted me 1900 to fix it. i refused to pay that much and brought it home and started taking it apart. i pulled the engine and laid it on the floor and hooked up my battery charger to the starter. i can turn over the motor with no prob. the issue i have is that when i continue to put a compression tester on one cylinder it will not turn over normally. it will always turn over without the tester. i need some help there. also, there was a lot of oil under the engine puddled all over. so, any suggestions would be appreciated.
