Brett, after talking with you yesterday about my 26% prop slip I called Howard Arneson to find out how I could get more bow lift. He said maybe that was not the problem and that he thought that the drives were trimmed to high allowing the props to slip more they should. After talking with him I picked up a power boat mag. to check prop slip on tested boats. I seemed to me that the bravo style drive/ prop had 10-12% slip like you said, but what was interesting was that all cleaver/ surface type props had 21% slip or more. Why is this? maybe I am not that far off w/ 15.5* instead of 17*

Thanks, Phil

Howards drives are designed to run on the surface. They are awsome drives They are great for boats that fly on their own. High slip on a boat running triple digits at 6500rpm is one thing. On a deep V like yours running 70 it is another. All surfacing cleavers do not run at 20% slip. Not hardly.

As we discussed and you stated, the bow wants to take control and steer the boat. The only way for you to get speed and control was to over trim the boat. OK, trim the drives back down as suggested by Howard. How is the drivability and slip percentage now? We know it gets worse. Yes it would be better to leave the drives in the water. Problem is, the bow stays planted. You need the stern planted.

Thanks Brett. I am starting to understand a little bit more how it all works.
