I'm looking for one. Any recommendations? Used is fine I have a good local prop guy... 8" setback adequate? seeing how I lightened up the bow and Whole boat? Thanks for your response. Any other prop recommendations? The lower is highly modded, no cav plate, 3 exhaust outlets where steering trim tab used to be. 3 liter fingerported, supposed to be a 285 dynoed balanced n ported beast. Getting ready to tear it down, boroscope showed some minor scratches on cyl walls still has 130 psi cold n dry but crc"d, so I will probrobly just do the whole thing. Who makes the best pistons for a motor like this? has cdi ignition w/7300 limiter. I've done many crossflows, 1st looper..... Any good thread recommendations? THANKS AGAIN!

There is a whole section on this forum of props, I would start there, and then facebook has a bunch of high performance boating groups you may find one. Another option is signature propellers, they make some good affordable props. they have an et cut and cleaver that work well. I have a signature series cleaver myself in 30 pitch on a lower revving combo than you are running. It works good for me using a light weight viper with a 2.0 mercury.
