What was the rpm at WOT?? Sounds like they are too big if you can only get 4600 out of them! I've got a set of stock 26 Bravo1's if you want to try them.

Didn't take them past 4600 because i knew i wasn't going to get 15 mph more like my stock 4 blades.

This is great tech info. Maybe the moderator can move it to the new Prop Talk section of Technical. It will stay up a lot longer and help more members there.

excursion: What did you do to your engines?

I suspect that your drives are really too low for the five blade so they have more blade area than you actually need. It would be interesting to see what a 28 Maximus would do.

I am running stock 28 B1s with my 496HOs. I may try labbed 28 B1s or labbed 30 B1s someday if the opportunity arises. 77.5 best speed with my stock setup. Seems as though I may have some more aerodynamic coneage on the boat this year over last year, so that may help speeds.

How would that help if she's tucked under the helm while your driving? Isn't that where everyone's girl likes to ride

I plan on having several sets of aerodynamic speed enhancers on board this season, and they can ride wherever they want. Why place limitations on oneself?
