STREAMLINED POWER
EXTENDED
All In-Line Four V MAX SHO® outboards are now available with 25-inch shafts. This brings V MAX SHO performance to multi-species boats, bay boats, pontoons and other 25-inch transom applications.
Features & Benefits
The In-Line Four V MAX SHO® design maximizes combustion efficiency in a way that no two stroke can, delivering clean, quiet power and performance.
The V MAX SHO® 175 and 150 feature Variable Camshaft Timing, which optimizes the angle of the intake camshaft to increase power and throttle response in the low- and mid-RPM ranges.
In-line Four V MAX SHO® designs are up to 40% more fuel efficient than traditional carbureted two strokes.
Precision Multi-Point Electronic Fuel Injection and long-track intake system combine to maximize power and fuel efficiency across the line of In-Line Four V MAX SHO® outboards.
An array of advanced sensors constantly provide vital atmospheric and engine conditions to the Engine Control Module (ECM), which instantly makes the precise adjustments for optimum performance.
With 50 amps for the In-Line Four V MAX SHO 175 and 150, and 35 amps for the 115 and 90, their alternators produce enough power for battery charging and a range of on-board electronics.
In-Line Four V MAX SHO® outboards feature mechanical controls for easy, convenient rigging with most bass, bay and flats boats, and are compatible with analog, 6Y5 digital or Command Link® gauges.
The In-line Four V MAX SHO® 175 and 150 now feature a tilt stop lever, relieving the pressure on your hydraulics during maintenance, trailering or extended storage.
