What’s in The Box?
STEERING FRICTION
You’ll find the 20hp very easy to control and comfortable to drive, thanks to its many features – from the front-mounted shift lever and single-lever steering friction adjuster to the light-load recoil starter. A built-in handle on the steering bracket and resting pads on the rear, make for convenient handling and portability too.
PRIME START
Start your outboard engine as easily as starting a car – even from cold. Exclusive to Yamaha, the Prime StartTM system ensure that the engine fires first time, every time you engage either the Electric or Manual Start.
HIGH OUTPUT ALTERNATOR
Never get left short. A High-output alternator ensures that power is always available to start the engine – even after prolonged periods of idling or when you’ve been running at low revs and using numerous accessories.
SHALLOW WATER DRIVE SYSTEM
Cruise towards the shore with confidence thanks to Yamaha’s Shallow Water Drive system. Offering ample protection for your propeller, it allows you to get as close as you need to be, no matter whether you’re cruising a murky lake or the crystal clear shallows of the sea.
F-N (Forward-Neutral-Reverse) GEARS FOR EASY CONTROL
Manual gear selection allows the engine to be warmed up in Neutral. The propeller will not turn until Forward is selected for safer idling. Ensures smoother acceleration and better control especially when turning. On Electric Start versions, the power supply to the starter motor is isolated until Neutral is selected.
HIGH-OUTPUT ALTERNATOR - keeps the power coming
The 20hp will be put to a wide variety of tasks, from fishing at night to coastal cruising, so its high-output alternator is a comforting feature, ensuring that power should always be available to start the engine – even after prolonged periods of idling or if you’ve been running at low revs and using numerous accessories.
FRESH WATER FLUSHING SYSTEM
An easy-access connector on the lower cowling allows you to easily flush salt and dirt from the waterways without having to run the engine – just connect a hose and you’re ready to go. This is a very efficient way to reduce corrosion and extend the life of your outboard.
