ISO of pair or triple outboards
Converting Al Copelands race cat to a double or triple outboard set up. Thinking 225+ hp each. Boat is around 9,000lbs.

31'. 9'4 wide at the widest. I might be shooting high. I mean its all fiberglass. Not much too it but seats. But its on a triple axle so im figuring over 5k. I only boat on about a 10 mile stretch of river. Ive always owned v hull big blocks. I still have the idea to stick with v8s. Just feel that outboards are more efficient/cost effective/easier maintenance. If i went inboards what do you think for minimum horsepower. Probably need surface drives.
