Outboard
Overview
Our V6 4.2-liter F250 is perfect for offshore dual or center consoles, walkarounds, runabouts and pontoons. It allows you to step up your horsepower and displacement without rerigging. Only now, it features a fresh, new cowling design (with engine-mounted Propeller Indicator Lights) if rigged with Helm Master® EX), new integrated digital electric steering* and rerouted exhaust for enhanced reverse thrust. It just proves even the best can get even better.
