I own a Triton 189 TRX with an E-Tec 150 H.O. mounted on a 6" Atlas hydraulic jack plate with a Raker H.O. 14 1/2 X 22 prop. Runs just over 60 gps WOT at 6000 rpm's. Looking for a recommendation on a 4 blade prop as well for this setup. Thanks.
You may want to try the new RX4 prop with its adjustable vents and propping your motor for around 5500-5800 may also improve top end performance. Everything is trial and error
