YAMAHA NEW MODELS


Never one to rest on its laurels, Yamaha has raised the bar with the release of two new 25 hp four stroke models, the F25D and the FT25F. Both engines are sleek and stylish, being easily distinguished by the new graphics and the Yamaha tuning fork emblem mounted on the cowling.

The two models are both four stroke engines and both designated as 25hp output at the propeller. The F25D is the standard model, while the FT25F is the high thrust version, best suited to operate on heavier boats. While both engines share a common powerhead — the structural difference between the two lies in their drive train. The FT25F uses the lower unit, bracket and gear box housing from Yamaha’s F40 model with higher ratio gears. This gives the FT25F the gear ratio for turning a low pitch dual thrust propeller, providing ample forward and reverse thrust for heavy boat applications such as barges or house boats.

Due to the varied applications of this four stroke outboard, the F25D is available in a multitude of different configurations. It is available as a tiller steer or remote control engine, with manual or electric starting, manual or power trim and tilt, and finally in a transom height of 20” for the standard lower unit or 25” for the high thrust model.

For the technically minded, both models have a twin cylinder four stroke powerhead that displaces 498 cm³. Weighing in at 78kgs, the standard F25D is in the lightweight category, making it appealing for owners of inflatables, RIB’s, dinghies, and barra-style boats. It is also an ideal kicker for trailerable yachts.

While EFI systems are common on Yamaha four stroke outboards from 30hp and above, Yamaha engineers have embraced the tried and tested single carburettor induction system on the new F25 models. The starting system includes a prime start system and decompression device. The prime start consists of a microcomputer that controls ignition timing and a carburettor to deliver precisely the right amount of fuel on start up. The decompression device ensures that manual or recoil starts are light and easy. Combustion efficiency and therefore fuel efficiency when under way is achieved through the micro computer controlling the ignition timing according to engine revs.

Operators will find the F25 models easy to control and handle. All the essential engine controls are conveniently grouped on the front of the engine and within easy reach. While some twin cylinder engines can be rough working through the powerband, Yamaha engineers have beaten the vibration problem with a counter balancer in the engine. The low vibration and low noise is top rate amongst outboards in its class.

Low exhaust emissions have for many years been a benchmark of Yamaha four stroke outboards. The Yamaha F25 is no exception. This engine exceeds the 2006 USA EPA emission standards and meets the US CARB emission standards and EU marine exhaust emission regulations.

Like all Yamaha outboards, the new Yamaha F25 incorporates a leading edge anti-corrosion system which provides exceptional protection of cooling passages and external components against saltwater and UV rays. There are five model variants, three in the regular F25D and two high thrust FT25D models.

Yamaha’s New Four Stroke 30hp Model With EFI Yamaha has released a significantly upgraded version of its four stroke 30hp model, the F30B. Based on the hugely successful F30A model, this latest offering from Yamaha is certain to delight Australian boaters who value fuel efficiency, low emissions and the very latest in outboard engine technology. This new model is easily distinguished by the new graphics and the Yamaha tuning fork emblem mounted on the cowling. Two model variants are available; F30BEHTL and F30BETL — both engines feature electric start (E), power trim & tilt (T), long shaft (L); the difference is forward controls and tiller steer versions.

At the heart of the Yamaha F30B is a 3 cylinder in-line block with a displacement of 747cm³. The low profile design and excellent power-to-weight ratio deliver optimum power for aluminium boaters, owners of RIBs and those seeking dependable auxiliary power.The Yamaha F30B comes standard with electric starting. Shaft length is 20” while the choice of tiller steer or forward control models are also available. Furthermore, boaters will appreciate the power trim and tilt system. The most significant system fitted under the cowl is Yamaha’s proven ECM — controlled multi-point electronic fuel injection system. Depending on speed and load, the ECM precisely adjusts the air/fuel mixture and ignition timing to ensure efficient and dependable combustion.

Overall Yamaha’s EFI system delivers sure fire starts every time. Regardless of temperature and atmospheric pressure, you can depend on simple turn-key starts.

When up and running, boaters will experience exceptional performance thanks to the long air intake manifold which is responsible for delivering additional torque through the power range.

Low exhaust emissions have for many years been a benchmark of Yamaha four stroke outboards. The Yamaha F30B is no exception. This engine exceeds the 2006 USA EPA emission standards and meets the US CARB emission standards and EU marine exhaust emission regulations. With the latest technology built into the Yamaha F30B, boaters will readily reap the benefits out on the water. At the fuel wharf, boaters will notice just how little fuel is used during a day on the water. Superior fuel efficiency has never been more important than it is in this era.

And whether under maximum power or trolling along the riverbank, the Yamaha F30B is a quiet and smooth operator. The variable trolling switch in the tiller handle allows the trolling speed to be adjusted between 650rpm and 900rpm in 50rpm increments.

The Yamaha F30B will accept the optional advanced digital network gauges (on models with forward controls), a suite of electronic instrumentation that is widely acknowledged as the best in the industry. And for tiller steer models, the F30B is fitted with the large multi-function tiller handle with all the functions required for engine control mounted on the tiller handle. Like all Yamaha outboards, the new Yamaha F30B incorporates a leading edge anti-corrosion system which provides exceptional protection of cooling passages and external components against saltwater and harsh UV rays. The freshwater flushing device is also standard.

When it comes time for service or routine maintenance, the YDIS (Yamaha Diagnostic System) is another great feature to help technicians determine the performance of the engine for quick and precise service work. Yamaha outboards are available through an Australia-wide network of authorised Yamaha outboard dealers. All Yamaha 4-stroke outboards are supported with a full 4-year manufacturer’s warranty and all 2-stroke outboards are backed by a 3 year warranty – standard conditions apply.
