Roger that, Brian.

Sandman's prop might get you where you want to be, certainly closer than the house mouse prop.

Along with the qualities you mentioned, PT Prop describes the OFS series similar to the Mirage.

I think Bigshrimpin mentioned the Mirage Plus works best at higher speed and higher rpm. I don't think you can have that on the 27 w a single 454/Bravo I without cranking up the output. Not sure what year yours is but I've read a few pages that claimed peak torque was achieved at 3800rpm, others @ 4200 rpm. I suppose gear ratio has something to do with that.

The PT Prop MQS 3 blade is a stainless equivalent to the Merc Black Max. They also make a 4 blade MQS.

Without having excess power, I'm pretty convinced there is not a better prop for the SeaCraft hull than the Black Max shape. It probably varies from motor to motor but I'm definitely sold on it.

It's kind of a blend of big round bladed big weight pushers and the more cut and raked speed props.

I'd ask around some other shops for a 15.5 x 17 or 15.25 x 19 Black Max (Merc) or Black Diamond (Quicksilver). Performance guy probably won't have those on the wall because they aren't designed for speed. The Alpha 4 is the Merc 4 blade variant of that shape. Both are all over ebay and CL for less than a Benjamin. Good luck.

P.S. dig that 21 photo!
