I agree with Shorty that if the motor starts and runs it isn't the capacitor. The function of a capacitor in electric motors is to give it a jolt of electrons when the motor turns on. Doesn't have anything to do with the motor torque after it reaches its operating RPM.
I guess the question I would have I this: when th e lift was first installed did the motor lift the boat OK, or has it always been marginal? If when first installed it had plenty power, then the wiring/connectors/switch might be the problem. Where did the hissing noise come from, the motor or somewhere else? If the motor you might need to have it repaired or replaced. If somewhere else you might have a loose connection in the wiring that, over time, arced until it can no longer handle the current. I had a problem with a circuit in my house one time....dishwasher wouldn't run but the supply showed voltage present. I finally went to the breaker panel and pulled that breaker...it had not been seated properly and arced over time to the point that the contacts were almost completely eaten away. There was enough of a connection to show voltage to the meter, but not enough metal to metal contact to pass the current necessary to operate the dishwasher. Compare it to hooking a garden hose and a fire hose to a common water supply. Both will register the same pressure (in electrical circuits voltage), but the fire hose will pass far more water (in electrical circuits, current, or amperes).
Good luck and let us know how it turns out!
