what all did you do to get that speed out of it.

I called Darrel at Jerry's Marine and he led me in the right direction. First thing I did was cut the Floatation Pods off the back, lowered the motor to where the Cavitation Plate is 1" above the Tunnel. Bought a 13 P Semicleaver Yamaha Prop and welded some Aluminum Trim Tabs on back to stop the Porpoising. I think I can get a little more out of it with somemore setup and Prop work.

are you running a stock 40?

I just bought a 18/44. Ran it yesterday and got 36.8. But that's with my cousin sitting on the bow to keep from porpoising. 14p Yamaha prop but I am going to need a little cup as it was blowing out with little trim.

U gonna have to beat dem trim tabs down a tad too

Did that after u left this eve

Now you're talking to the "Charlie Daniels of the torque wrench" when it comes to Mercury outboards. Darrell has forgotten more than any 5 of us will ever know about Mercury outboards, and more specifically about how to make then fly. Darrell belongs to a unique club, the 80+mph tiller club. Listen to what he tells you and do it! He's my brother by another mother:D
