Yamaha 300hp V6

The Yamaha F300 V6 is a powerful and durable 4.2-liter DOHC V6 EFI engine featuring SBW electric steering, DBW throttle and gearshift, TotalTilt™, and a 70 A alternator. The large displacement delivers strong torque and quiet operation, and the engine is fully compatible with the Helm Master EX system.

Yamaha F300 V6 is the flagship model of Yamaha’s Offshore series, combining the massive torque of a 4.2-liter V6 engine with a lightweight design and the latest digital control technology. The large 4169 cm³ DOHC V6 delivers instant acceleration and strong pulling power across the entire rpm range, making the F300 the perfect choice for large console boats, day cruisers, cabin boats, and professional use.

The engine supports Yamaha’s latest SBW (Steer-By-Wire) system, which offers completely play-free and maintenance-free electric steering. DBW throttle and gear make operation smooth and precise, and the engine is fully compatible with the Helm Master EX system, including automatic trim, course control, and advanced maneuvering functions.

TotalTilt™ speeds up trimming and tilting with a single push of a button, and a powerful 70 A alternator (55 A charging capacity) keeps the boat’s electronics running in all conditions. PrimeStart™, TCI ignition, and Yamaha’s quiet exhaust system ensure reliable starting and a pleasant sound.

Variable trolling speed control allows for fine-tuning the speed in 50 rpm increments, making the F300 V6 an excellent choice for fishing as well. Yamaha’s legendary corrosion protection, serviceability, and the durability of the Offshore series make this engine a long-lasting partner for demanding conditions.
