i used to run a 15/42 semi-v alweld with a yammy forty in sabine, it would do about 44 or so with my duck huntin gear.... it would eat the 25's.
then had a 15 marsh runner we ran with a mega 25 with 50 carbs, etc.... it had a 50 inch bottom but even with a load still ran a good 40+
they were getting 85 horsepower out of some of the 40 mercs but it was hard to find a hull that would use all the power without pounding you to death.
