I have a friend that is suppose to be picking up his new boat latter this week. He got a 06 294 with a 200 Mercury Opti. Currently the motor does not have a prop but he is suppose to tell them before he picks up the rig what prop he wants. The boat does have a 6"plate. He normally fishes with 2 people in the boat. He is hoping this boat will be a low 70ish ride. I know they are many variables in speed... conditions/driver ability/set up. I think based on what I have read here on this board that 70-72 is achievable. Any advise on what prop and once the motor is broke in what engine height.
