Repower I/O Qs.

[macojoe]

Chevy 250, in a boat puts out 165 HP at the motor, from a different came then stock, same motor in car gets 140 hp.
I believe that at the prop this is about 130 or so?? I forgot.
WOT on a cuddy 5000 rpm will get you low 30's But will rode nice in the mid 20's

Thats what I had when I got my boat, I have converted to outboard now by bracket and a 175 hp, I get wot 5500, 40 mph (light load) Ride around all day low 30's

I run 15 X15 1/4 prop on both the I/O and OB, gives me best out of hole with heavy loads, 3 guys + gas + 200 # fish, 100# ice

thats whats best for me.
