Lightweight, compact and economical. Our single cylinder portables, F6, F5, F4

and F2.5, have been designed to be ultra-easy to use and feature a specially

developed four stroke, OHV design delivering excellent combustion efﬁciency as

well as economical and smooth running.

For easy starting, these engines feature an auto decompression device ﬁtted to the

camshaft. This system releases pressure in the cylinder when the manual pull start

is engaged allowing the user a much lighter pull starting experience.

For convenient transport and mounting, all models are ﬁtted with an economically

designed grasp on the front of the motor and large carry handle on the rear. The F4,

to store or transport the engine on either side or its front without leaking engine oil.

Designed to be versatile performers, Yamaha’s F4, F5 and F6 all feature ﬁve

step adjustable trim allowing the user to adjust the operating angle of the engine

according to boat load or water conditions. These engines also feature a 3 step

shallow water drive offering added manoeuvrability in shallow conditions.

In-built fuel tanks on all engines in this range means these engines can go with you

on any adventure. For extra range the F4, F5 and F6 also have the ability to connect

to an external fuel tank.
