Been lurking for a year now since I bought my 97 240 Sundeck. Pulled into slip Saturday, raised lift enough to hold boat stationary, let my passengers off, then tried to lift out of water and the motor just hummed. Won't go up or down. Both pulleys and the belt will turn by hand. AO Smith 3/4 hp motor. Called one dock specialist to take a look, he says $675 for a motor and switch before he even comes out. (I can buy both for $250 delivered, so he is a bit too high) I was thinking just start capacitor or spraying some electric motor cleaner as it is not a sealed motor. Any thoughts/experiences? Thanks.
