Prop Testing 232 Interceptor

I did some further prop testing with my 232 Interceptor and thought I would update the results from last year. The boat has a 320 HP 6.2L Mercruiser with a 1.65 Bravo One drive. All speeds are GPS and rounded to the the nearest 1/2 mph as different runs gave different decimals as the condition changed. The results are as follows:

Props :------------------------20 Enertia-------------22 Enertia-----------21 Vengeance------------21 Mirage (detuned 23)----23 Mirage---------23 Tempest

Holeshot---------------------- Excellent --------------Very Good------------Excellent-------------------Very Good------------------Good--------------Very Good

3000 RPM ---------------------27 mph-----------------30 mph---------------31 mph--------------------33 mph--------------------34 mph--------------34 mph

4000 RPM----------------------39 mph-----------------43 mph---------------42.5 mph------------------44 mph -------------------45 mph--------------45 mph

RPM @ WOT-------------------5,400--------------------5100------------------5200-----------------------5100 -----------------------4800-----------------4950
-----------------------------Hit Rev Limiter
GPS speed WOT---------------55.5-----------------------57.5------------------58-------------------------60---------------------------60-------------------61

I am a little surprised how little difference there is between the props. Some have slightly better holeshot but really none are bad. The Tempest is just slightly faster but it is oddly perceptibly louder. I actually prefer the 23 Mirage out of the bunch for its quiet very smooth ride. It carries a load of people without losing much speed and stays on plane at a very slow 18 mph. The 21 Mirage is good too but slips a bit at high trim because detuning removes some cup. Honestly, other than the 20p Enertia which was too small I would be happy with any of them.
