Yamaha F90XB2 90HP in White 25″ Shaft Standard Rotation Remote Mechanical

Yamaha F90XB2 90HP White Offshore

The Yamaha F90XB2 pairs an L4 1.8L 16-valve SOHC engine with standard rotation, finished in Pearlescent White at 364 lbs dry — a strong power-to-weight ratio for premium fiberglass center consoles and offshore hulls. The 25-inch extra-long shaft and 2.15:1 gear ratio are built for high-transom platforms in Mulmarine’s reliable marine propulsion systems lineup that need consistent propeller immersion during oceanic transits.

White I-4 Offshore Performance

The F90XB2’s 1.8-liter block in Pearlescent White matches the aesthetic on luxury center consoles, maximizing air intake and torque output for rapid hole-shot acceleration under load.

Extra-Long Shaft Versatility

The extra-long 25-inch shaft is calibrated for deep-V offshore vessel transom dimensions, preventing propeller aeration in following seas and holding a secure grip on the water surface during turns.

Pro Maintenance Care

This digital EFI engine runs high-quality sacrificial anodes to prevent galvanic corrosion in saltwater coastal environments. Pro Tip: flush the engine with fresh water after every launch to maintain the cooling system and protect internal components from salt buildup.
