The brand behind every reliable engine
Reliable coverage beyond your warranty
Yamaha’s award-winning V6 4.2-liter outboards have been offshore favorites for more than a decade. Initially, boaters were attracted to their power, efficiency and intelligent design. After years of proven performance, our V6 4.2-liters have become known for something perhaps even more valuable offshore—reliability. In fact, with legendary 97 percent reliability,** they’re one of the most trusted V6’s offshore. Well, now these trusty outboards are turning heads again, with a fresh new look and new, integrated digital electric steering—making them even more responsive. Our V6 Offshore outboards have proven once again that even a trusted favorite can take an exciting turn.
Miles offshore, there’s nothing more important than your outboard’s reliability. Over years of proven performance, Yamaha’s offshore 4.2L V6 has recorded 97 percent reliability.** This outstanding track record makes it an even smarter choice offshore.
Yamaha’s 4.2-liter V6 Offshore outboards feature plasma-fused sleeveless cylinder walls, which are 60 percent harder than steel. That means larger cylinder bores for increased displacement, resulting in more power and torque, without increasing outer cylinder dimensions. It also results in dramatically lighter weight and better cooling, and “micro-textured” cylinder walls that help decrease friction loss, and further increase performance and enhance reliability.
For maximum power and efficiency, electronically controlled throttle valves work in concert with Precision Multi-Point Fuel Injection to ensure a precise mix of air and fuel. In addition, six individual sensors constantly provide vital atmospheric and engine conditions to the Engine Control Module (ECM), which makes adjustments for performance.
From the top of the cowling to the tip of the propeller shaft, every ounce of weight-savings has been realized for maximum performance without sacrificing durability.
Yamaha’s Variable Camshaft Timing system advances and retards the angle of the intake camshaft to dramatically increase power and throttle response in the low- and mid-RPM ranges. This feature helps Yamaha’s new 4.2-liter big-bore V6 outboards deliver awesome hole shot and mid-range acceleration.
The Yamaha V6 Offshore F300 and F250 are the industry’s very first offshore V6’s offered in digital models with built-in electric steering. This makes them incredibly responsive and also results in a cleaner bilge, with no pumps, hoses, hydraulic lines or connections.

Yamaha 4.2L V6
Our 4.2-liter F300 is a reliable, offshore favorite—and it's only getting better. It now features a fresh, new cowling design (with stern light if rigged with Helm Master® EX), new integrated digital electric steering*, rerouted exhaust for enhance reverse thrust and is available in Yamaha gray or pearlescent white. It’s destined to be a top choice offshore for years to come.
*Mechanical F225, F250, and F300 models remain unchanged. 4.2L V6 Offshore 225 compatible only with bolt-on digital electric steering.
Our 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 stern light 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.
Perfect for 20-foot decks or deep-Vs, the versatile 4.2-liter F225 allows you to increase your displacement without replacing your rigging.
† Weight refers to shortest shaft length, and is measured without motor oil, gearcase oil and propeller (except models 25 hp and under, which include a standard propeller). All Jet model weights include the jet pump assembly (weight estimated).
