Yamaha's F70 jumps to number one

YAMAHA has announced that since it released its F70A in May, sales have been exceptionally strong and has now become the company's top selling four stroke motor - by a substantial margin.

“I can’t recall a motor release that has had such an immediate impact,” said Brett Hampson national sales and marketing manager for Yamaha Outboards in Australia.

“The reality is many people have been considering purchasing a four stroke in this horsepower bracket but the power options that were available were either not suitable for their application or their boat. With its light weight and powerful performance, the new F70A is the motor customers have been waiting for.”

Yamaha said the immediate popularity of the F70A is partly due to the size of the craft the motor has been designed to power. The F70A is ideally suited to boats in the 4.5m to 5.5m class which happens to be a very popular category in the Australian boating market. This category encompasses a huge range of boats from family runabouts to serious mid-size fishing rigs. Ymaha said on these craft, the F70A has proven to be a beautifully balanced and highly responsive power option.

The F70A runs a four valve per cylinder, four cylinder design. This increases the intake area by 17 per cent compared to the F60C and results in greater volumetric efficiency for outstanding acceleration and impressive top speeds.

The F70A uses a single overhead camshaft rather than the conventional dual camshaft design for 16 valve engines. This reduces the weight that would result from having an extra camshaft and the components that go with it. It’s this feature, as well as a range of other weight savings throughout the design that make the F70A the lightest engine in its class, it’s 35kg lighter than it’s nearest fourstroke competitor and 21Kg lighter than its nearest DI two stoke competitor, according to Yamaha.

A higher gear ratio has been utilised on this motor allowing the F70A to spin a larger propeller, getting more power to the water for more grunt. The F70A uses Yamaha’s “K” series of propellers, giving customers a wide selection of pitch and diameter variants to ensure the right prop is available for every application.
