I traded my 19p tempest plus for a 21p tempest plus, but the 21 was damaged at some point and reworked. here is what is happening. With the 19, I was running 52mph but hitting the rev limiter. With the 21 I am getting to 50 mph and slowly climbing, and then if I turn, or hit any sort of a wave/wake it blows out, engine hit rev limiter, and speed drops to 47mph. Is my engine too high, or was some of the grip taken out of the prop when it was reworked?
