2019 Yamaha VF175 In-Line V MAX SHOÂ® - 20 in. Shaft
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. Overall, this series of 1.8- and 2.8-liter dynamos features a surprising tech package with 16 valves, single- or double-overhead cams and electronic fuel injection”for maximum efficiency and high performance. This makes the I-4 V MAX SHOs perfect for smaller bass, flats and bay boats and other performance hulls. With the option of a 25-inch shaft for all of our I-4 V MAX SHO outboards, anglers prowling big waters on multi-species, bay and flats boats have a competitive edge that runs deeper than ever.
Power & Performance
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.
Reliability & Durability
Unbeatable Reliability: The I-4 V MAX SHO 175 and 150 feature a Cowling Drain System and Air Intake Labyrinth System to trap and drain water that enters their cowlings during normal operation.
Better Lubrication: Wet sump pump lubrication that uses a pressurized oil delivery system through an oil pump.
Engine Warning System: This system protects the outboard with a range of functions including: overheat protection and low-oil-pressure warning (automatically reducing maximum RPM to 2000), over-rev protection, water-in-fuel detection, start-in-gear protection and shift-in prevention at open throttle.
Corrosion Protection: Combined with our proprietary alloy (YDC-30), our exclusive Phaze Five electro-deposited, anti-corrosive paint system provides a tough, five-layer barrier against corrosion. This protection is standard on all Yamaha I-4 V MAX SHO four-stroke engines.
Convenience & Control
Extra Space: A four stroke in-line design means there's no need for an external oil tank. That means less weight and more storage room in the boat for tackle and gear.
Ample Charging Power: At 50 amps, the V MAX SHO 175 and 150 alternators boast an 11 percent increase in charging power over the two stroke 150 HPDI.
Easy Rigging: I-4 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.
Model Specific Features
Lean and mean, the I-4 V MAX SHO 175 delivers exhilarating hole shot and class-leading top speed. It clocked in at 62 mph with a tournament load”five mph faster than its VF150 sibling.* (*Tests conducted by Yamaha Marine using a Skeeter ZX190 with a tournament load and two occupants.)
