Re: prop

You'll burn up your motor. If its sitting that high the intakes for the impeller (water pump) are out of the water. Even if they were in the water...being that high up you will not get any thrust..only cavitation

Re: prop

Probably not. What engine do you have and what kind of boat is it on?

Re: prop

It isn't the position of the prop you should be looking at. The antiventilation plate (the flat plate just above the prop) should be even to an inch above the bottom of the hull.

Dont cut the transom...great way to ruin the boat. Tashasdaddy's answer is the best one and cheaper than getting a new motor!

Yep. It bolts to the transom, you hang the motor from it, and then you can adjust the motor up and down a couple inches, how much depends on the jack plate you get.
