And I think my performance indicates your assertion is incorrect. There is a good reason to have your engine all the way down (at least a 100HP 20" Yamaha). My performance is at the top of the scale. It is unlikely I get much more performance out of these huills. If I lift the engine up, could it be better? Well, there is no reason to try. It just doesn't get much better. Is it theoretically possible? Perhaps. And I believe that is your point.

I don't think it is a foregone conclusion that an engine should always be lifted up some. At this point I will sit back and try to stay out of this. I said my peace and I have too much respect for you (Tom) to want to spiral this down. We may just have to agree to disagree.
