As fast as the wind can carry it.
Depends on how fast the boat is.
Answer now.
First, it needs to be mounted on the boat. And the boat determines how fast the attached motor will go. If the boat is wood, then it will likely float deeper in the water, and not be particularly fast. If the boat is a smaller fiberglas one, then the motor and boat will go faster. Based on much boating experience, I would say that most boats could go 30 to 35 mph with the 40hp Merc.
1 million miles an hour
150MLP
