Sydney International Boat Show 2007

The Australian boating public has had their first look at Yamaha’s new F350 V8 outboard. Now on its way to the Sydney International Boat Show, the new Yamaha F350 delivers unprecedented power to weight performance from the world’s first V8 production outboard engine.

The new Yamaha F350 is the first four stroke outboard motor to utilise a V8 powerhead. With a displacement of 5,330 cm3, the 32 Valve DOHC V8 engine delivers a maximum power output of 257.4 kW (350 hp) at the prop shaft, which is the highest horsepower rating for an outboard motor in the world today.

Since its international release at the Miami International Boat Show in Florida, Australian boaters have waited several months to catch a glimpse of Yamaha’s latest powerhouse. Available in the final quarter of 2007, the new Yamaha F350 is a highly prized piece of marine power equipment.

“We knew Australian boaters would really appreciate the power and performance of our new V8 outboard,” said Brett Hampson, National Sales and Marketing Manager for Marine Products at Yamaha Motor Australia.

“This new model is a huge boost for the Australian market and now boat manufacturers and boaters alike have a realistic power alternative to the traditional sterndrive system. This is great news for boaters who demand both outboard power and a big offshore hull.”

The massive power and torque of the F350 ensures a big boost in speed, acceleration and performance. Larger multi-hull boats will appreciate the torque advantage of a V8 engine when moving several tonnes of hull onto the plane with a 45% increase in thrust than a conventional 250hp 4-stroke outboard.

Variable Camshaft Timing is again utilised to give the F350 more torque at low and mid-range rpm. Also increasing power, the In-Bank Dual Exhaust with Power Surge Chambers is used to relieve pressure in the exhaust ports. A larger gear shaft is also adopted for greatly increased strength plus an automatic rpm synchronization function can be employed for multi-engine use (up to 3 engines).

Unlike any other design profile in the Yamaha line-up, the new-look F350 commands attention. The sleek outboard profile efficiently stores the 60° V8 engine under a cowling that features twin breather vents more akin to a world super bike design. It is simply stunning.

Durability is further enhanced with forged motor mounts and an oversized mounting bracket to minimise noise and vibration. To accommodate the increased displacement, a larger thermostat, large-capacity water pump and dual-course coolant supply system are adopted to improve cooling capacity.

An exclusive new-design drain system has also been developed inside the cowling to quickly drain away any water that gets inside the cowling and reduce the amount of water intrusion to one-tenth that of conventional outboards.

In keeping with strict environmental emission regulations, the Yamaha F350 qualifies as a 3-star rating under the 2008 emissions standards of the California Air Resource Board (CARB).

Yamaha outboards are available through an Australia-wide network of authorised Yamaha outboard dealers. The Yamaha range comprises trusty and dependable two stroke models from 2hp to 200hp, High Pressure Direct Injection VMAX models from 150hp to 200hp and low emission fuel efficient four stroke models from 2.5hp to the world’s largest production outboard- the 350hp V8 Yamaha F350.
