      3-position storage system prevents oil leaks

      When taking your engine to and from the water - or storing it - the last thing you need is a messy oil leak. Yamaha's unique engine breather system allows the engine to be stored on its front or either side without danger of oil leaking onto your dock or deck - or into the boat locker or car boot.

      180º steering with friction and throttle adjustment

      Handling is a joy, thanks to the simple steering friction control adjustment and the ability to steer a full 90º turn to left or right, which makes light work of tight turns and docking. Throttle trim is easy to adjust too, so when you're out on the water, you can be sure of great stability and control, even at high speed.

      Optional lighting coil gives 12V 6A power supply

      The convenient option of a lighting coil and voltage regulator/rectifier provides a reliable 12V 6A power supply for running lights or charging batteries. Great for a bit of exploring or fishing at night!

      Built-in fuel tank with switch-over facility for remote tank

      The handy built-in 1.1 litre fuel tank is great for portability and makes more room for gear in the boat, whether that's another box of bait, or an extra cooler of refreshments. For longer trips, simply plug in a remote tank (available as an option) and twist the 2-way tap.
