What size engine do you recommend?

The RackRider 3.7 is designed for short shaft engines in the 4 to 6hp range. These engines typically weigh 25 to 27kg and can be carried by most people. If you find these engines too heavy then a 2.5hp engine can be used. 2.5hp engines will weigh between 12 and 17kg meaning almost anyone can carry them, but they will be unable to plane the boat. The RackRider 3.7 is a very pleasant and frugal boat at displacement speeds and I personally travel at these speeds often if I am exploring the upper reaches of waterways. When choosing engines in the 4 to 6hp range, unless you will be using the boat as a one person boat then I suggest opting for the 6hp engine. There is no weight penalty and it has 50% more power than it’s 4hp  brother. This is a small, light craft designed to push the performance boundaries when using low power. Saying that, it does have to comply with the laws of physics and there is a big difference in performance between to 4 and 6hp engines.
