Curious of those who have a 21 TRX with a 250 Mercury Four Stroke what kind of speed, and rpm you are getting out of it. And what prop you are running? Finally opened up my new to me 21TRX today and I have a feeling that the motor is not getting full throttle when running. The boat came with a 24 Fury. Motor has about 22 hours on it. Holeshot is very sluggish and wide open rpm is only about 5700, speed is about 65-68. Just seems like this boat should be turning more rpm at wide open throttle..
