AIR TIME

check where your propshaft is to the keel. boats that we call deep are 6'' to 8'' = mirage or rev 4 props. b1s are good for 5 1/2'' to 3'' for heights, 5 blades 4'' to 0''. on the 5 blades px5 max 5 are bow lifting, p5 are more stern and for cats. the rev 4 is a great prop the deep or stock heights. imco shorties work well on most boats and most pick up 2 to 6mph. I picked up 8 with a carb change and 2'' shortie on my baja 24 ol with 650hp went from 5200 to 6000rpm = 76 to 83 plus. more with a prop change. good luck. Art
