MFS50A

What is the one thing every boater looks for in an outboard motor? The lightest weight motor possible. Tohatsu’s 50hp four stroke now comes in a second color option, Beluga White, allowing boaters to choose which engine color best fits their boat. You asked and we listened by outfitting the 50hp EFI four stroke with an improved gear case with a lower gear ratio, giving you the increased low end torque your boat needs.

This outboard also has variable idling speed control from 650 to 950rpm’s. And the MFS50’s stainless steel water pump housing liner gives you outstanding durability. With the 50hp four stroke’s power to quickly reach your destination, exceptional fuel performance to keep gas costs down and proven electronic fuel injection technology for worry-free boating, you’ve never had a day on the water quite like this.
