Rick said at one time that a 3 blade Predator was a great prop on an older Eyra, if you could find one.I think a 23 4 blade may be too much for an older 150, maybe a 23 tempest. Rpms will drop some going to a bigger wheel from the 21, so it will be a little easier on the engine. I dont think a laser II would help performance.64 is pretty strong, and the older 150 didnt have a rev limiter, but make sure youve got plenty of oil going! Some guys even add a little to the gas tank.96 Eyra/12 Mercury 175 Pro XS with 2015 single axle trailer2017 Victory Gunner
