The new F20 delivers fast acceleration and enhanced boat performance under load, so when it’s time to hit the water, you won’t have to leave anything (or anyone) behind. The variable trolling rpm switch makes the F20 the perfect fishing companion, while the easy to use fresh water flush attachment makes the engine a breeze to clean at the end of the day. Built-in ergonomic carry handles and two-position resting pads make it easy to remove and store the F20.
