    Prop / RPM question

    Don't know much about this stuff: I have a 2015 RT 188 Ranger w/ 115 Merc Omax (2 stroke). 6" JP, 21p Lazer II prop, at WOT getting 57 mph / 5250 RPM's. I'm happy with the speed but does more RPM's mean More speed? I believe the motor max RPM's are 5,800. To get more should I raise the JP, lower the JP? I also have a 20p Lazer II, should I try that? Thanks!!


    Have a good one and thank God for it!

    Yes, you should try the Lazer 20 P. You should be around 5500 and a bit more speed ... maybe.
