[> Original Prop -- Bruce, - Thursday - 09/10/09 - 12:52pm

1:1, Okay - thanks very much. Now how about the prop? Do any of you know the original prop size and pitch? I have a non-original three bladed prop which is rather small diameter, and I believe it is undersized. If I had the original prop info. I could calculate the ideal three blade prop specs. Has anyone have three blade prop specs for our boats?
