Tohatsu 40TLDI

[CajunChristian]

Those marshrunners are heavy boats. If I had to guess, mid 30's. Anything more than that is a bonus. You may wind up turning a 14 pitch prop. That motor with a 14 will get on plane in about 10' distance and hit the rev limiter within 50 yards. You could go to a 15, hole shot will suffer. You may need to do like most of us do, have a river prop and a marsh prop. These units have a 2.08 gear ratio, that usually means that they turn 1" pitch higher than the old 40's and 50's we used to run, they had a 1.93 or 1.95 ratio.
