Downside to leaving outboard motor prop in water?
My boat does not have a motor mount that can be retraced out of water. And the well will not allow me to tilt it out either.
It has a hole/well at the back of the cockpit in front of the transom through which I lower the outboards's prop. There is a cover which protects the motor from weather.
During freezing weather I understand the benefit of storing the outboard in the cabin. But it's a pain in the butt to lug the thing up into the cockpit every time I want to go for a sail.
So.... aside from the risk of getting frozen water in the outboard, is there any downside to leaving the prop in the water indefinitely? Again, the upper portion of the motor is protected from the rain etc by the motor well's cover. Many boats in my marina appear to leave their outboard props submerged. Most have a retractable mount or tilt it out.
