MFS40 - Proven Reliability, Performance & Versatility

Introducing the lightest weight in its class, EFI 40hp four stroke. Outfitted with a sleek four stroke design, the MFS40 comes in two color options, Beluga White and Aqua Marine Blue, allowing you to choose which color best fits your boat. Starting at just 209 pounds, you will not find a lighter weight motor in its class.

This outboard is equipped with proven technology, including electronic fuel injection (EFI) and digital CD ignition, which provides quick throttle response, excellent fuel economy, and very smooth rides on the water. The MFS40 also has a high output 21 amp alternator for superior battery charging. The adjustable steering friction and trim tab reduces your amount of steering effort, making for an easier and more enjoyable boating experience. Convenience is also covered with the 40hp four stroke’s built-in freshwater flushing system, making routine flushing quick and easy.
