I was loading my boat on Tuesday when it felt like I had spun a prop. When I started checking, the hub was fine but the prop would spin freely with the motor in gear. Its at the dealer getting checked out. The Service manager told me that Merc is putting an electrical shift actuator in the lower unit, that isn't sealed, that has been causing some issues like mine and that Merc had a service bulletin out on the issue. Hopefully that's all that is wrong and not more. It sucks though with only 8 hours on the motor.
