25-30 M.P.H DEPENDING ON BOAT
The speed a 40hp motor can achieve while pulling a tube depends on various factors, including the weight of the tube and riders, water conditions, and boat design. Generally, a 40hp motor can pull a tube at speeds ranging from 15 to 25 mph. However, optimal speeds for tubing are typically around 20 mph for safety and enjoyment. Always consider local regulations and safety guidelines when tubing.
It all depends on how heavy your vehicle is.
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.
