V MAX Sho Inline 4 175 / 150 / 115 / 90 HP
The In-Line Four V MAX SHO four strokes have achieved the unthinkable—packing signature V MAX SHO hole shot and acceleration into streamlined designs. This powerful family now includes the all-new I-4 V MAX SHO 90, which packs the biggest punch of any 90-horse on the water.
Make an appointment with Tom Ross to come in and see these motors in person.
Quiet Power and Performance
The I-4 V MAX SHO® design maximizes combustion efficiency in a way that no two stroke can, delivering clean, quiet power and performance.
Midrange Power and Response
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.
Fuel Efficient
In-line Four V MAX SHO® designs are up to 40% more fuel efficient than traditional carbureted two strokes.
Optimum Power
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.
Power Management
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.
