Here are the details of the 2 choices; both are about the same price.
For you guys that don’t know my last boat it was a twin Whippled SBC powered 28 Daytona that kicked butt. Everyone said it would not go over 110mph and it ended up going 149mph. I liked how it was different but it was really hard to sell.
