speeds with 502's? 525's? 540's? 575's?
fuel capacity?
weight?
any flaws?
I have recently became interested in the 31 and am just looking for any info you guys could throw out there. love the old school look! I understand they are heavy for there size, we boat on lake Michigan and I think this hull would foot the bill for the bigger water.....

I'm going to say just south of 9k dry and 80 with 575's.

Fuel capacity 180 gallons
Weight 9,500 lbs
575's will get you in the 80's 502's probably low 60's

500s will run 72 in smooth water and 75 in big water
