GLH I hear ya and understand ya I'll post as soon as I know.

Here's a formula that may be of use to some of us sometime into the future

sq root of new hp / sq root of old hp x old speed = new speed

My dealer up here just did one. As I recall, he was in the low 80's. I'm guessing those motors were around 800hp.

I'd say 73. Yep 73.
I've never seen a brand B pull more than 75.

Probably gonna need those 30's. Doub't if she'll pull the 32's.

Good luck, and remember... BOAT means Break Out Another Thousand.

My guess: 84-87

PBM tested one with 575's,
ran like.......... 82.
Your buddies boats running
more boost, should be worth
a couple of ticks.

Not quite enough info, but I'd take a stab at it and say somewhere in the mid 84.5 ? Those 5s & 10s are hard to come by.

Post One motor and drive is on the boat,

he is waiting for dyno time to dyno one of the motors. The second drive is ready to install. I would say a week and a half at the most. More than likely a week.
