Yamaha F150XD2 150HP – 25″ Shaft Remote Mechanical

Yamaha F150XD2 150HP EFI 4-Stroke

The Yamaha F150XD2 pairs an L4 2.7L 16-valve DOHC engine with remote mechanical steering, finished in Pearlescent White at 487 lbs dry — an industry-leading power-to-weight ratio for responsive acceleration. The extra-long 25-inch shaft is engineered for high-transom center consoles that need consistent propeller immersion and stable cooling during high-speed transits.

Peak output holds through the 5000-6000 RPM band via a Precision Multi-Point EFI fuel induction system. The 2.00:1 gear ratio translates mechanical energy from these reliable marine propulsion systems into low-end torque for instantaneous hull planing. US coastal boaters rely on this Japan-engineered platform for reliability navigating challenging offshore environments.

F150XD2 DOHC Tech

The 16-valve DOHC configuration maximizes air intake flow for rapid, responsive hole-shot acceleration, letting offshore boaters push heavily loaded fiberglass vessels through choppy sea conditions.

Yamaha 150HP Induction

This engine uses Precision Multi-Point EFI to optimize combustion cycles, preventing power loss and ensuring instant turnkey starting across varying atmospheric pressures.

25-Inch Power Shaft

The extra-long 25-inch shaft is calibrated for deep-V vessel dimensions, preventing propeller ventilation while maintaining secure mechanical leverage during turns.

150HP 50-Amp Alternator

This engine’s upgraded 50-Amp alternator powers a full suite of modern electronics, keeping navigation displays and sonar equipment functional throughout the day.

Yamaha Limited Warranty

The F150XD2 is protected by a 3-year limited factory warranty covering critical structural or mechanical defects.

White Offshore Match

The Pearlescent White finish matches luxury center consoles, with a 487 lbs build balancing displacement and planing speed on open coastal water.

Engine Care Protocol

This four-stroke engine requires minimal routine maintenance thanks to its robust internal components. Pro Tip: flush the internal cooling passages with fresh water after every saltwater outing.
