I have a 09 Ranger 1860 Angler with a 2015 Evinrude 150 HO with a 17p viper on it and am getting 44 at 5500 rpm looking for what prop i need to get more speed and rpm closer to 5900. The motor is the highest it can go. Or what kind of manual jackplate and setback i should look for. I have tried a raker 22p and that gave me 47mph at 5050 rpms. Does anybody have a 19p Rebel i could try?
A 19" Rebel would not work well on that boat and it would lower the engine rpm too much. The Rebel is designed more for mid-range fuel economy than for top speed.
Perhaps a custom prop shop could tweak the 22" Rebel to allow the motor to rev up higher and get into its powerband. The Viper is a good all around prop and you may need to try a few different sizes to see how they perform.
