Re: doel fin vs stingray on 50hp johnson 16' alum boat
Have you tried trimming the engine in, that should keep it from going so high.
As far as the 2 fins they are the same but different, you shouldn't notice a diffence between the 2 and either one should do you well.
My boat came with a doelfin but I ended up making my own from a peice of 3/16 aluminum plate(I do that sort of stuff).
