I had a the same problem with a Avon SR4 and a merc 40 Blueband, after fitting smart tabs it was a different boat ( I also fitted a 50hp suzuki four stroke at same time, so that helped also ).

Smart tabs defiantly kept the nose down and made getting on to the plane a lot easier. I am selling them if your interested

I may be completely misunderstanding your post but I think there lies your problem.
