RELIABLE LUBRICATION AND STORAGE
Yamaha’s new F4 and F6 both feature a pressurized oiling
system. They can be stored on either side or on the front grip
without fear of oil leakage, due to Yamaha’s exclusive Easy
Storage Oil Retention System.
COMFORTABLE, CONVENIENT CONTROL
The carburetor and its setting is factory-selected for
maximum fuel effi ciency, helping these outboards achieve
a 3-star C.A.R.B. emissions rating. Additionally, automatic
decompression, built-in auxiliary priming, and start-in-gear
prevention help make for easy, safer starts.
EASY OPERATION
A 1.1L see-through fuel tank is built in, with switchable access
to an optional external tank for extended range. A tilted, waterresistant fuel fi ller cap and built-in fuel strainer add to both the
convenient operation and reliability of these outboards.
With a dynamically-balanced and dampened large twist-grip
throttle, 180-degree steering, and large F-N-R shift handle;
comfortable, convenient control is key.
VERSATILE PERFORMANCE
A 5-step trim adjustment couples with a 3-step Shallow Water
Drive System to help make these outboards perform in various
conditions. A splined propeller shaft and an expanded selection
of available propeller sizes give you performance that’s versatile
and easy to handle and operate.
