23 / 25 / 26
 

Advise or Experience appreciated,,,,,
23 mirage plus
25 mirage, rework specs same as Plus
26 hydromotive 4blade
23&25 are 14 3/8 Dia.
26 is 15 3/8 Dia.
All 3 have good slip numbers overall (8%-13%) while maintaining 8-10 at cruising at 4000rpm. Can only turn 26p 4700, would I be have any positive gain decreasing the diameter of the 26? Can turn 23 5400 and 25 5100.

Potentially, yes.
Need to know all the performance data for each prop. And, very important as well is the boat and engine data.
Q4 is a stern lifter.
