I have a stock 454 mag turning a bravo 1. It's only seeing 60 mph and spinning 4400 @wot. What size prop should I use to get 5000 out of it? I have a 22p 4 blade on it now, would a 20p get me 600 rpm? Thanks

You will gain approximately 300 rpms per 2" of drop in pitch. The smallest Bravo I Mercury makes is a 22p. Mercury makes a Revolution 4 that we have had good luck with when the engine can't quite pull a Bravo I. The Rev 4 ranges in pitch from 15p to 25p.

Will they have that selection in LH also?

All but the 15p
