I Run a 90 gun 509/575's Teague power,26 pitch 4 blade bravo's trs drives.run 73-74 4 people 3/4 full of fuel. On gps speedo. I run with Kvogt alot.

What's your guess on 800 a side min, Konrad, prop size? Strong mid range accel with respectable top end? I was thinking a 28 pitch gets 85 mph, am I close?

I would say damn close...800 HP may need 30P

Thanks for the feed back. I guess I have the right props,I bought 26 pitch props couple years ago before I started this project. Been a long ordeal. Just about over. Should have props back from shop next week.

Yes you'll need 30's

The konrads are -2 shorter I believe then a standard TRS and claim just a swap of drives is 3-4 mph everything being equal. Good luck with the boat.

850 a side, Konrad PRS III Drives. 94 Gun runs 90mph... Best ever on the gps is 92

Are the Konrad PRS III surface drives? Konrad claimed 5-7 mph gain with the TRS upgrade, -1.7" replacements. So I would think 4mph is a more realistic number...? Anyone run a non surface drive, 90s Straight bottom, pleasure layout, close to or north of 95mph???

The Konrad TRS swap gains are typically 3-5 mph with the increased propshaft height.

my bad, not sure where I heard 5-7mph, wishful thinking I guess.....
