Im running 23 pitch quicksilver torrent 3 blades turning 5300 at 68 gps in flat water if it helps. I was running 25 pitch 3 blades and could only turn 4900 rpm. I have outboard props on my boat and it really lifted it out of the water at w.o.t. it feels like a 26 foot boat. When I run the 25 picth mirage props it feels like a 40 foot boat glued to the water. They guy tells me it is the cheepest way to get me with in a few miles per hour with out spending the money on labbed props. Ask for Bill Sr. 800-338-8900 Prop shop. He will blow you away with his info I think he has 100 years experiance in props. I have a 38 flat deck with 600 H.P. 468 Tall deck roller motors Dyno at 600 H.P. a peice. Bill is located in Algonac Michigan right by Sunsation

Those 5 blades are costing you speed because they lift the transom up. You need 4 blades set up for bow lift. I have been down this road before.
