I have a 72 evenrude 65hp with the selectric push button gear selection. My problem is the motor seems to be stuck in gear but when I go to start it I can turn the key and it hardly has enough balls to turn the motor over . Now when I pull the spark plugs and crank it spins over like nothing but as soon as compression is added the starter struggles to spin the motor over . Is my starter done or is there anything I can do to test before I spend more money lol .
