INBOARD PROP QUESTION

[Gary Hill]

I'm in the process of repowering my 1976 inboard from the oringal mercuriser 233 to a 310 HP 350 Marine Power and I have a prop question since the Seacraft book show's that it came with a 16 X 17 prop, and I was told the prop on the boat was a 17 x 17 which would turn 3800 (motor spec's required 38K to 42K), I was wondering if someone has the similiar set up for a starting point? I plan on using Jerry's Prop Co. to start with but would like to keep the prop changes to a minium. I hav a right hand motor for sale and trans,if anyone is interested. Motor has good compression and most new bolt on item's, trans had a rear seal leak is the reason I pulled it out and then decided to update. I would like to hear the thought's on 4 blade Vs 3 blade benefit's.
