Yamaha Marine has announced a series of innovative upgrades to its premium V6 outboard range.

The improved Yamaha V6 range shares design cues from the company’s flagship XTO, with new features including Digital Electric Steering (DES), Thrust Enhancing Reverse Exhaust (TERE) and Yamaha’s exclusive TotalTilt™.

Yamaha’s Premium V6 segment now offers extensive functionality, from everyday use and long-distance journeys to high octane sports use.

New 250 – 300 hp V6 Engines

Digital Electric Steering (DES) is now built-in to the 300 - 250hp V6 engines equipped with Steer by Wire (SBW), delivering a smoother and more intuitive driving experience, with no hydraulic systems to bleed or steering cables to snag. Non-SBW 300 - 250hp V6 engines are fully compatible with optional bolt-on DES or traditional hydraulic steering systems.

Yamaha’s exclusive TotalTilt™ function allows complete tilt up or down (until trim ram contact) from any position with a simple double-push of a button, with a buzzer sounding to alert others to keep clear of the outboard and an integrated tilt limiter to prevent inadvertent damage.

Augmenting the outboards reverse thrust and control, the Thrust Enhancing Reverse Exhaust (TERE) keeps exhaust bubbles above the anti-ventilation plate and out of the propeller below 2500 rpm, ensuring the prop only bites bubble-free water. Combining TERE with optional DES and the Helm Master EX joystick will enhance manoeuvrability around docks and confined spaces.

Taking much of the styling from the XTO, the new 4.2-litre 300 - 250hp V6 engines now feature a colour-matched lower unit, a new one-piece top cowling with water-draining air duct moulding, a new bottom cowling, apron shape and premium graphics.

The lower unit has also been improved and features the new design of the gear tooth profile with improved contact and reduced surface pressure. In addition, the durability has been improved by changing the oil flow inside the lower case and the bearings that support the gears.

New 225hp V6 Engines

The new Yamaha 225hp V6, designed with the same styling as the 250 - 300, is also fully compatible with optional DES and includes the TotalTilt™ function and TERE.

The large displacement cylinder block, like the bigger V6s, features a unique long intake manifold, in-bank exhaust, an electronic control module (ECM) controlled fuel injection system and variable camshaft timing (VCT) resulting in improved reliability and fuel efficiency.

New Drive by Wire Side Flush Mount

Yamaha is also introducing its new Drive by Wire (DBW) 6X9 side flush mount control, designed to bring the benefits of the Helm Master EX to a broader array of premium boats.

The DBW side flush mount uses Yamaha’s latest electronic control system bringing smoother, more precise control through the power range. Easy to install, users will enjoy its ergonomic design and premium feel single-function buttons.

The DBW side flush mount is suitable for single-engine configurations from 150hp and above Yamaha outboards.

The new Yamaha V6 range and new DBW Side Flush Mount system are available from 2022 season.

Yamaha has more international brands on display than previously to give visitors a greater choice of powered craft and RIBs for a lifestyle afloat at today's Southampton boat show. From WaveRunner PWCs, trailer-boats, high performance RIBs and day-boats to fishing craft and offshore cruisers, Yamaha has something to suit every pocket and performance wish.  

Around the show key models from Anytec, Ballistic RIBs, Chaparral (new model), Cobra RIBs, Draco, Finnmaster, Jeanneau, (with new models), Linder, Ribeye (new PRIME model), Rigiflex, Robalo, Sealegs, Whaly, White Shark and Zodiac are on show, with a range of Yamaha outboards from 2.5 to 300hp.

The new portable Yamaha F2.5B, the “baby” of the outboard range, is shown for the first time in the UK with deliveries to dealerships already under way.  The new model has lower emissions than the previous 2.5, better performance and even more features which are outlined in the separate release. 

Although the Ballistic 4.3m is the smallest of the Ballistic RIBs it still retains the solid build quality and outstanding handling that all Ballistic RIBs are known for. Ballistic RIBs are used by military and law enforcement agencies across the world, including the Metropolitan Police in London, the South African police, the Norwegian police and the Fisheries Protection Service in Sierra Leone. Versions of Ballistic RIBs are also widely used by coastguards, harbour masters and dive clubs.

#ROWING: Outboard motors worth up to €20,000 were stolen from the National Rowing Centre in Cork at the weekend. It is understood that rowers from the High Performance Programme were staying at the NRC when thieves took the engines, which were attached to catamarans and tinnies moored on the water. The raid did not come from the land.

Rowing Ireland has advised that anyone who becomes aware of 15HP Hondas and 20HP Yamahas being offered for sale should contact the Gardaí.

Sharks in Irish waters

Irish waters are home to 71 species of shark, skates and rays, 58 of which have been studied in detail and listed on the Ireland Red List of Cartilaginous fish. Irish sharks range from small Sleeper sharks, Dogfish and Catsharks, to larger species like Frilled, Mackerel and Cow sharks, all the way to the second largest shark in the world, the Basking shark. 

Irish waters provide a refuge for an array of shark species. Tralee Bay, Co. Kerry provides a habitat for several rare and endangered sharks and their relatives, including the migratory tope shark, angel shark and undulate ray. This area is also the last European refuge for the extremely rare white skate. Through a European Maritime and Fisheries Fund (EMFF) project, Marine Institute scientists have been working with fishermen to assess the distribution, diversity, and monthly relative abundance of skates and rays in Tralee, Brandon and Dingle Bays.

“These areas off the southwest coast of Ireland are important internationally as they hold some of the last remaining refuges for angel shark and white skate,” said Dr Maurice Clarke of the Marine Institute. “This EMFF project has provided data confirming the critically endangered status of some species and provides up-to-date information for the development of fishery measures to eliminate by-catch.” 

Irish waters are also home to the Black Mouthed Catshark, Galeus melastomus, one of Ireland’s smallest shark species which can be found in the deep sea along the continental shelf. In 2018, Irish scientists discovered a very rare shark-nursery 200 nautical miles off the west coast by the Marine Institute’s ROV Holland 1 on a shelf sloping to 750 metres deep. 

There are two ways that sharks are born, either as live young or from egg casings. In the ‘case’ of Black Mouthed Catsharks, the nursery discovered in 2018, was notable by the abundance of egg casings or ‘mermaid’s purses’. Many sharks, rays and skate lay eggs, the cases of which often wash ashore. If you find an egg casing along the seashore, take a photo for Purse Search Ireland, a citizen science project focusing on monitoring the shark, ray and skate species around Ireland.

Another species also found by Irish scientists using the ROV Holland 1 in 2018 was a very rare type of dogfish, the Sail Fin Rough Shark, Oxynotus paradoxus. These sharks are named after their long fins which resemble the trailing sails of a boat, and live in the deep sea in waters up to 750m deep. Like all sharks, skates and rays, they have no bones. Their skeleton is composed of cartilage, much like what our noses and ears are made from! This material is much more flexible and lighter than bone which is perfect for these animals living without the weight of gravity.

Throughout history sharks have been portrayed as the monsters of the sea, a concept that science is continuously debunking. Basking sharks were named in 1765 as Cetorhinus maximus, roughly translated to the ‘big-nosed sea monster’. Basking sharks are filter feeders, often swimming with their mouths agape, they filter plankton from the water.

They are very slow moving and like to bask in the sun in shallow water and are often seen in Irish waters around Spring and early Summer. To help understand the migration of these animals to be better able to understand and conserve these species, the Irish Basking Shark Group have tagged and mapped their travels.

Remarkably, many sharks like the Angel Shark, Squatina squatina have the ability to sense electricity. They do this via small pores in their skin called the ‘Ampullae of Lorenzini’ which are able to detect the tiny electrical impulses of a fish breathing, moving or even its heartbeat from distances of over a kilometre! Angel sharks, often referred to as Monkfish have a distinctively angelic shape, with flattened, large fins appearing like the wings of an angel. They live on the seafloor in the coastal waters of Ireland and much like a cat are nocturnal, primarily active at night.

The intricate complexity of shark adaptations is particularly noticeable in the texture of their skin. Composed of miniscule, perfectly shaped overlapping scales, the skin of shark provides them with protection. Often shark scales have been compared to teeth due to their hard enamel structure. They are strong, but also due to their intricate shape, these scales reduce drag and allow water to glide past them so that the shark can swim more effortlessly and silently. This natural flawless design has been used as inspiration for new neoprene fabric designs to help swimmers glide through the water. Although all sharks have this feature, the Leafscale Gulper Shark, Centrophorus squamosus, found in Ireland are specifically named due to the ornate leaf-shape of their scales.
