Hi Tom - I notice the same thing on my 30-1 - as I increase revs the stern squats. I have a two blade fixed prop on an Atomic 4. I sometimes adjust the throttle by looking over the stern rather than the speedo - kinda handy. At high revs my exhaust is completely underwater while it is a few inches above water at rest.
I don't know if it is really a problem or just a matter of physics - my power boat does the same thing, albeit more drastically.

While motoring if I increase the speed the stern starts squatting the faster I go. I top out at 6.5 knots of speed and the stern is way down. I have a martec 18'' folding prop and I do not know the pitch. Tom Vincent Frolic II 1979 36' C&C _______________________________________________ This List is provided by the C&C Photo Album.
