correct prop/pitch for 20' w/ 175 opti

[DonV]

OK...OK.....I don't get too much into this prop thing, however who cares what it runs at WOT?? How many times you gonna run wide open??? To me it's what prop works best with the LEAST effort from your engine at the normal speed you run, using the normal loading of the boat, the safety of the boat, etc. You do not want the boat to struggle to run your NORMAL cruising speed. You want the engine to use the LEAST effort to cruise.....at let's say 4000 rpm @ 30 mph. Your bank account will thank you!
