This is a joke, right?
What I got after a long boring wait was a sales video for an auto pitching prop set to something that sounds a bit like the soundtrack to a 70s luuuuurve film. As far as the current prop discussion goes it's irrelevant. other than to clearly demonstrate low pitch = good hole shot, but crap top speed & vice versa.
Yep, the prop does what it says on the tin, but bow lift? No f***ing wonder - 150Hp on a boat that can't weigh much more than 400Kg with a prop at half the pitch it would normally have for fast running? That's not bow lift, that's vertical take- off, perfectly explainable by a simple beam balance round the CoG of the boat! I could get my Humber to do that if I put the anchor at the stern & stuck a 7" prop on it!
I think we're just going to have to agree to disagree on this one......
On the plus side, the vid does show quite well where your hull sits when on the plane, and how a subtle adjustment of weight up forward could make a huge difference to the angle of the hull relative to the water. (jumping back to Malthouse's post.....)
