Multi-Function Tiller HandleTohatsu MFS15E

Stop Switch, Front Shift, Friction Adjusting Screw and Power Tilt Switch (PTS: on power tilt models only) are integrated into the tiller handle for convenience.

Stowable Carrying HandleTohatsu MFS15E

We’ve incorporated a carrying handle on the front that can easily be tucked away when not in use.

Fuel Water SeparatorTohatsu MFS15E

A high quality, user-friendly fuel water separator is standard equipment on all EFI 20 | 15 | 9.9 motors. This unique yet simple fuel water separator doesn’t require the use of a single tool to drain the water.

Center of Gravity ImprovedTohatsu MFS15E

By moving heavy components (i.e. crankshaft, driveshaft) 30mm forward compared to the previous model, the tilting weight has decreased by 26% from the previous version, making it much easier for users to tilt manually.

Compact Fuel System Layout for Easy MaintenanceTohatsu MFS15E

The Vapor Separator Tank (VST) has been designed to integrate the high pressure fuel feed pump, regulator, and fuel cooler into one component.
