Yamaha F250 MechanicalLighter

From the top of the cowling to the tip of the propshaft, every ounce of weight savings has been realized for maximum performance without sacrificing durability. There's even an advanced polymer composite lower engine pan that lowers weight and increases corrosion resistance.

Yamaha F250 MechanicalQuicker

Yamaha's Variable Camshaft Timing system advances and retards the angle of the intake camshaft to dramatically increase power and throttle response in the low- and mid-rpm ranges. This feature helps Yamaha's 4.2-litre big-bore V6 Offshore Outboard to deliver awesome holeshot and mid-range acceleration you have to feel to believe.

Yamaha F250 MechanicalSmarter

Air enters the engine block and is routed through a single 75 mm electronically controlled throttle valve. This works in concert with the Precision Multi-Point Fuel Injection System to ensure the precise mixture of air and fuel for optimum power and fuel efficiency. The reduction in friction from the Micro-Textured Cylinder Walls further increases the amazing fuel economy!

key features
  • 4.2-litre big bore displacement: By using a highly advanced, thermally applied plasma fusion process on the cylinder walls, Yamaha's new line of V6 Offshore outboards have no conventional steel cylinder sleeves, yet the cylinder walls are 60% harder than steel. That means larger cylinder bores for increased displacement, resulting in more power and torque, without increasing outer cylinder dimensions. It also results in dramatically lighter weight, better cooling, and "micro-textured" cylinder walls that help decrease friction loss, and further increase performance and enhance reliability.

4.2-LITRE BIG BORE DISPLACEMENT

By using a highly advanced, thermally applied plasma fusion process on the cylinder walls, Yamaha's new line of V6 Offshore outboards have no conventional steel cylinder sleeves, yet the cylinder walls are 60% harder than steel. That means larger cylinder bores for increased displacement, resulting in more power and torque, without increasing outer cylinder dimensions. It also results in dramatically lighter weight, better cooling, and "micro-textured" cylinder walls that help decrease friction loss, and further increase performance and enhance reliability.

THROTTLE RESPONSE AND ACCELERATION

Yamaha's Variable Camshaft Timing system advances and retards the angle of the intake camshaft to dramatically increase power and throttle response in the low- and mid-rpm ranges. This feature helps Yamaha's new 4.2-litre big-bore V-6 Offshore Outboard to deliver awesome hole shot and mid-range acceleration you have to feel to believe.

CRUISING SPEED

Yamaha V6 Offshore 4.2 Liter is up to 19% faster at cruise rpm than other competitive four-stroke outboards. Cruise rpm is where most offshore outboards are typically operated, meaning you get there faster, using less fuel, than competitive models.

PATENTED SHIFT DAMPER SYSTEM (SDS)

Yamaha's patented new Shift Dampener System (SDS) greatly reduces noise commonly associated with shifting gears. Using a special new design and components, much of the resulting force is absorbed, resulting in far quieter and smooth operation. Initially available on Saltwater Series II - SDS propellers, which are ideal for these outboards and their typical applications.

PROTECTION FROM THE ELEMENTS

All Yamaha V-6 Offshore Outboards feature a proven cowling drain system, to easily and efficiently drain away any water that enters the cowling during normal engine operation. Incoming air is routed through a labyrinth of passages that trap and drain water before it enters the engine's intake, for maximum reliability.

PROTECTION AND POWER

Yamaha V-6 Offshore Outboards feature an exhaust pressure reduction system, which not only helps keep the propeller hub cooled from hot exhaust gases, it also helps provide more power by helping to force those gases out of the engine.

INCREASED COOLING CAPACITY

Yamaha V6 Offshore models come standard with dual pairs of water inlets, for increased cooling efficiency. Located on the front and both sides of the lower unit, each pair of pick-ups operate independently of each other to provide proper water flow in a wide variety of applications and conditions.

RELIABILITY AND EFFICIENCY

4.2 litres of class-leading displacement teams with individual intake and exhaust camshafts to provide more precise valve timing control with fewer moving parts than conventional rocker arm systems for increased reliability. This superior design also allows for use of 4 valves per cylinder which exchange intake and exhaust gases more efficiently for responsive power and increased fuel economy.

VIBRATION REDUCTION

Yamaha V-6 Offshore Outboards utilize a new version of our Long Span Mounting System, which employs a speciallyformulated rubber compound attached to newly-designed engine mounts. Placed as far apart vertically and horizontally as practically possible, they provide necessary strength while minimizing vibration.

SMOOTH AND QUIET

Engine exhaust is routed through a maze before exiting above the waterline through the idle exhaust relief outlet, for unbelieveably smooth and quiet operation.

ADVANCED TECHNOLOGY

Six individual sensors constantly provide vital atmospheric and engine conditions to the Engine Control Module (ECM), which instantly makes the precise adjustments for optimum performance and efficiency.

 

Buyer’s Guide to Boats and Pontoons

Boats

When you think about it, buying a boat is a little bit like getting married. After all, this is the commitment of a lifetime, and you want to feel confident you’re making the right decision! Fortunately, there are plenty of fish in the sea, and plenty of boats and pontoons to choose from here at Howell’s Marine Sales & Service. The following tips can help you narrow down the options and find your perfect match!

Choosing a Boat

What kinds of activities are you interested in? This should be your guiding question when choosing a boat. If catching fish is on the agenda, you should seek out a fishing boat, with features such as rod holders and livewells. If you want to pursue the excitement of watersports, you should look for a boat with a powerful engine that can reach high speeds. Meanwhile, if you are looking to host parties on the water, a spacious luxury boat will serve you best.

That being said, there’s no need to limit yourself. There are some boats that can cover all your bases! Pontoon boats, for example, are incredibly versatile. We are passionate about pontoon boats here at Howell’s Marine Sales & Service, and we recommend them to our customers who want to get a little bit of everything out of their boating experience.

Budgeting for a Boat

Of course, you can’t talk about buying a boat without discussing all the costs involved! The upfront cost of purchasing a boat can be pretty steep, but the long-term costs are even more important to consider. When budgeting for a boat, remember to account for all the expenses that are going to add up over time – such as fuel, maintenance, and insurance.

Generally speaking, it’s a good idea to set aside at least 10% of your boat’s total value each year for routine maintenance, and another 5% for any unexpected repairs. Meanwhile, you can expect to pay about 1.5% of the total value of your boat annually for insurance coverage.

If you have any questions about the boat buying process, you are always welcome to consult the sales team here at Howell’s Marine Sales & Service! We are always happy to assist. You can find us in Chatham, ON, near London.
