Hey Michael, the PT web site says the OFS series is similar to the Merc Mirage +, which is a pretty good prop. However I tried a 3B 15.5 x 17P version, and it wasn't as good as my 4B 14.125x20P Michigan Apollo, but neither one would turn over 5200 rpm. A 4B version of the Mirage + and the 4B OFS would probably be a little better. BTW, PT's web site lists all OFS4 props as 15.25" diameter, so I'm not sure you could turn a 15P version up to at least 5300 rpm.However the $269 is a dynamite price for a 4B SS prop! My 4B Apollo was $360 in 2007. Most 4B SS props are in the $400-500 range nowadays!
My choices if I were picking 4B SS props at this time, would be:
1. 14.5 x 15P BRP Cyclone
2. 14 5/8 x 16P
Michigan Apollo
3. PT OFS4 15.25 x 15P
4. PT ELE4 15 x 15P
Both the Cyclone and ELE turn 5400 rpm on my boat with a heavy load but the Cyclone is 2-3 mph faster and at least 10% more efficient. Don't know what the Apollo and OFS would turn. If I were you, before I spent that much $, I guess I'd check with Ken at Prop Gods to see what he recommends. I think he's in the Tampa area near you, and I believe he'll exchange props till you find the best one.
I'll email you my prop test spreadsheets tonight. Denny
