Better performance - 18x42 or 18x48 tunnel hull?

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.

[toodeep]

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.

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
