I have a non technical question, really just for amusement.

I have a 93 basstracker Deep V17, aluminum fishing boat. I scored a 1989 Mercury 100 2 stoke 4 cyl, with less then 20 hrs on it. The reason I bought the motor is i'm converting it to a jet for running the river I live on. However, this time of year the river comes "up" and you could just about run anything on it. I'm going to wait till the off season to swap the lower units but i'm going to put the 100 on the boat this weekend and run the prop for the fall. The boats rated for 90 hp max but with the jet conversion it will be about a 70hp outboard so im not concerned about that so much.

My question is I get 29mph max with the 40hp Evinrude (high pitch prop) on the boat right now, GPS veriified, what do you guys think it might achieve with the 100hp running a prop?
