While most props prefer to be just below the surface, there are some that want to be run deep. If you are running a 3 bladed aluminum or stainless prop, start at 3 holes up. See http://www.whalercentral.com/articles...cle_id=106 from the Reference/Articles/Motors and Rigging section.

This will set the engine up 1-1/2", which is all the height needed for top speed potential of the rig. I would recommend a Mercury Enertia SS prop. If you are going to use aluminum props, consider the Mercury Spitfire 4 bladed aluminum.
