Re: cavatation plate hight
From thread, "Need Ideas to stop porpoising" - FYI
Re: Need ideas to stop porpoising? [Re: Fr. Frank] #64703 - 08/01/08 05:57 PM Edit Reply Quote 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! Post Extras:
