Props for a Pantera 24

It was definitely looser than the Bravo and the QIV, but I like to run a little loose. But not quite as loose as my Mirage. The Bravo threw my boat all over the place in the slop and needed a lot of trim.
Honestly, the best way I can describe the Rev 4 on my boat is the equivelent of a "4 blade Mirage".

Out doing a little prop testing last night...
2 guys, 1/2 tank, full cooler, 80°F, 10mph winds, a ripple - 6" chop.
First, a ø14.5" X 28p Mach Stern Driver 4 blade prop.
Top speeds:
73.1mph at 4600rpm into the wind.
74.0mph at 4700rpm with the wind.
Out of the hole, this prop broke free some and required a little bit of feathering. The boat ran nice and level with a good attitude. In hard corners the prop did start to brake free.
With a little tweeking to get the rpm up, I think the top speed would increase some.
Second, my labbed by BBlades ø15.25" X 28p Merc Bravo 1
Top speeds:
74.6mph at 4800rpm into the wind.
75.3mph at 4900rpm with the wind.
My B1 is still the best 4 blade prop that I've run on my boat.
Best top speed, best out of the hole, and does not brake free in corners...
Next up will be a stock 27p M+...

A basically stock 1997 Merc 502MagMPI with Stainless Marine exhaust. I did rings, bearings, oil pump, and a valve job about 150 hours ago. When the heads were done, they did also have some pocket porting done. The cam is original so I think it probably only makes 25-30HP over an all a stock 502Mag with cast exhaust.
