What was done to the p4 bc prop? I’m looking for a new prop my my bay boat that has a racing cat tunnel hull with a center pod and a 300r merc. I’ve slung blades on 3 pro max props and the pro et is no longer made sadly because that prop ran amazing so I’m looking for a new prop that is NOT labbed or has had the blades thinned.
Here is what I don't understand, my boat has a prop on it stamped 12.5 X 19--yet on line catalogue calls for a 12.5 OR a 13.5--how can the diameter be different for the same engine?
The diameter is a recommendation. You do have a max diameter that can be run before the prop hits the cavitation plate. Take into account blade flex as well on softer metal props. More can be found on diameter by watching some of the great videos on youtube. Search Prop Diameter
Excellent video,,,,,,,,,,,, Thanks so much for taking the time to test and put up. Steve's good to know if you have a prop....

Max 5 are very stiff. I had to have mine worked and resized to 15” diameter to get it running right.
nice
