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
That is a good place to start. I assume that you have a G2 150, is that correct?
Propping is trial and error, don't forget.
As was mentioned earlier, everything in propping is trial and error as each hull and engine combo performs differently.
Record your rpm, speed and fuel consumption at each 1000 rpm and at full throttle and post it here with a comparison to your Raker II results. It would be interesting to see how the two compare. The RX4 was designed for the tremendous low-end torque of the Evinrude E-TEC G2 series and performance varies when installed on earlier engines.
