But you should be using the same prop. Yamaha Saltwater Series 15.25" x 17" pitch. Or, you could use a PowerTech OFS4R17, which is a four-blade prop in 17" pitch. Either one should spin up to rated RPM at WOT, and give good performance. That is a heavy boat for the single engine, so you definitely don't want an aluminum prop. Brian
