Hi Mustang,
so what prop did you end up settling on and what did you get as far as WOT rpm & speed as well as best cruise rpm, speed and lt/hr or klm/hr
I'm looking at the Power tech ELE4 15"P as the OFS4 15P might be a bit too much for me as I'd like to get another 100~200rpm more than my current Mirage Plus 15P. This loaded sees 4500rpm wot and light loads give 4670rpm and recommended is 4400~4800. I like ot prop to top of WOT when light and middle when loaded. I've also run the hifive 17"P and this is good at cruise and above 21knots but very poor ecconomy when you have to come back in rough weather to 17 knots or so as the bum just wants to come off the plan where the mirage plus holds it on the plane well at low speeds.
I'm mainly chasing stern lift, good cruise and ecconomy with low speed planning for my Whittley 660 cruiser thats got a Mercruiser 4.3L 220hp MPI donk.
The mirage plus give me around 1.4klm.lt at 22knots and 3100rpm.
Cheers Mark
