Yamaha F175XA 175HP EFI 4-Stroke 25″ Shaft Outboard Motor

Yamaha 175HP F175XA EFI 4-Stroke 25in Shaft

The Yamaha 175HP F175XA is a robust 2.8L in-line four-cylinder outboard featuring a 25-inch shaft and mechanical control compatibility. Built as a versatile workhorse for both new boat builds and repower projects, this 2785cc model utilizes a 16-valve DOHC design to deliver reliable torque density and lightweight efficiency. The mechanical soul of the F175XA emphasizes simplicity and power, utilizing Variable Camshaft Timing (VCT) to produce aggressive low-end acceleration while remaining significantly lighter than traditional V6 outboards in the same class.

Focused on superior operational durability, the F175XA utilizes Multi-Point Precision EFI for instantaneous throttle response and optimal fuel management. The engine is protected by specialized anodic coatings and Yamaha’s proprietary Phaze Five™ paint system to combat galvanic wear in high-salinity marine environments. Maintenance is made effortless by the front-mounted freshwater flush port and easy-to-access internal service points. This unit includes a high-output 50-amp alternator, ensuring a stable charging system for navigational electronics, livewells, and essential shipboard safety gear during long transits.
