I`m in sales. Your "salesman" is a tool!

Picture this in your mind. Your cav plate is well below the keel. What really happens when you trim up? The plate digs in like a shovel and pulls the stern down. This will happen even if they are level. That`s why it needs to be higher. This is true of ALL motors. PERIOD.

This is also killing performance and mpg. Not to mention the boats running attitude. Your`s too.

Fr. Frank has forgotten more about props than most "pros" will ever know. He tested props for a living. Bushwacker was an engineer at Pratt+Whitney. Tool or rocket scientists? I`d tell the tool to come by CSC for some edumacatin!
