The all-new Yamaha 90-horsepower In-Line Four V MAX SHO® may be the smallest in the V MAX SHO® line, but it packs the biggest punch of any 90-horse on the water.
Its SOHC four-valve-per-cylinder design minimises weight while optimizing combustion. In fact, its lightweight design combined with 1.8L displacement makes the VMAX SHO 90 the class leader in torque and top speed. A reconfigured gear ratio also gives the VMAX SHO 90 greater holeshot and improved top-end speed over it's F90 sibling. The all-new Yamaha VMAX SHO 90, the latest addition to the VMAX family.

Features
1832cc 16-Valve SOHC Marine Engine
With its increased 1.8 litre capacity and single overhead camshaft, four-valve per cylinder design, the new F90 delivers improved acceleration and power-to-weight performance.
ECM Micro-Computer Control
This outboard is controlled by an advanced microprocessor Engine Control Module (ECM), which receives inputs from six major sensors located throughout the engine. This information is used to ensure the engine runs at peak performance, by delivering the right fuel/air mixture to each combustion chamber.
High Output Alternator
A 12-Volt 35-Amp high-output alternator ensures that power is always available to start the engine, even after long periods of idling or running at low revs. This not only provides extra starting power, but delivers sufficient power to run the wide array of on-board electronic devices used in modern boating.
Larger 81mm Cylinder Bore
The previous-generation F90 used a 79mm cylinder bore, in the next-generation F90 the cylinder bore size has been increased from 79mm to 81mm which provides more efficient power delivery. A larger valve has been used for increased transfer efficiency for both intake and exhaust.
Offset Crankshaft
The crankshaft design is offset by 5mm from the centre of the cylinder. This innovative design decreases internal friction and promotes a more efficient transfer of power to the crankshaft.
One-Piece Cowling
This engine features a new outer cowling design with an intake air drain system, to easily and efficiently drain away any water that enters the cowling during normal engine operation. Incoming air is routed through a labyrinth of passages that help trap and drain water before it enters the engine’s intake, for maximum reliability.
Single Bore Throttle Body
The 60mm wide single bore throttle intake minimises intake resistance and provides first-rate response for brisk-acceleration and high-speed operation.
Single-Ram Power Trim and Tilt Unit
The compact and light-weight single-ram power, trim and tilt (PTT) unit and bracket have been developed exclusively for this engine.
Variable Trolling Control
Yamaha’s variable trolling control allows the skipper to precisely adjust the engine’s idling speed from 550 to 1000 RPM in 50 RPM increments. The ability to finely tune the trolling speed allows fisherman to perfect their lure presentation when chasing different species of fish.
Rigging Componentry
6Y5 Digital Round Gauges
Yamaha’s conventional digital multi-function gauges provide the real-time data required to maximise outboard performance and fuel efficiency. The two and three gauge illuminated display options provide rpm, trim, oil, speed, distance, time, overheating, battery, fuel economy/flow/consumption stats. F200B models.
Command Link - 6Y8 Round Gauges
Using Local Area Network (LAN) technology, these digital round gauges provide accurate and real-time tachometer, speed and fuel management stats, including fuel flow/consumption/economy (up to two tanks), trim level, battery voltage, push button trolling speed adjustments and more.
Command Link - 6YC High Definition Gauge
This high definition, colour display uses Local Area Network (LAN) technology to deliver accurate and real-time stats for single and twin engine setups. The customisable day/night gauge delivers information on fuel flow/ economy/ consumption, trim level, battery charge, speed, push button trolling and more.

The ergonomic design features a thumb operated trim and tilt switches built into the handles, as well as shift and throttle control functions, for convenient and comfortable operation. F200B models.
Genuine Yamaha Propellers
Prop choice makes a huge difference to outboard acceleration, top-end speed, handling and fuel efficiency. That is why Yamaha continues to push the technological boundaries in the design and development of our leading range of high performance props - ensuring every Yamaha outboard performs at its peak.
Yamaha Shift Dampener System
Many of Yamaha's mid-range and high horsepower props come with Yamaha’s exclusive Shift Dampener System (SDS). This system absorbs forces created when an engine shifts in and out of gear, resulting in a quieter, smoother and ‘clunk free’ shifting.
Alloy White K Series
These props deliver Yamaha's high-quality design and performance in a low-cost, lightweight propeller. They offer a good all-round choice for Yamaha outboards, coming in a wide range of sizes and pitches to suit every power requirement.
Alloy GP K Series
The newly released aluminium GP introduces a renewed blade geometry and Yamaha’s Shift Dampener System (SDS) for ‘clunk free’ shifting to the K series of props. Suited to lighter hulls, this exceptional prop delivers improved acceleration, speed, fuel economy and anti-ventilation.
Aluminium SDS K Series
These high-quality aluminium props are ideal for heavier hulled boats such as fiberglass and plate aluminium, as well as modified V-type hulls, catamarans, pontoon and commercial work launches. Incorporating Yamaha's Shift Dampener System (SDS), these props deliver quiet and smooth shifting.
Performance Series 3/4 Blade
These specialised stainless steel props can enhance boat performance and improve how they handle particular conditions. The four-blade prop is ideal for rougher conditions and when greater acceleration is required, such as towing. These props are now available with Yamaha’s Shift Dampener System.
Remote Control Security System
Yamaha's optional Customer Outboard Protection (Y-COP) engine immobiliser system is easy to use and highly effective in stopping unauthorised start-ups when your boat is unattended. Simply push the button on the neat and simple remote to lock and unlock the engine.
