New Yamaha motor

[CJH]

I am not engineer, but I am pretty sure its easier to hit the emissions standards with the 4's than the 2's. At a certain point it becomes a point of diminishing returns. (I.E. it costs more and more to get the same results on a 2 that you would get with a 4, thus making it not feasible)

Over time the standards are only going to get tougher.......

[TonkaBass]

I would totally put a four-stroke on the back of my boat if it did what I wanted it to, the only thing I am wondering is how they will compare with the competition as far as price goes. This new motor probably is pretty spendy!

[CaptZ21]

If yamaha is getting into 4 strokes for bass boats, you can bet all your Uncle Ben's rice there is a future market. Never say never about most things, simply look back in time and how many things have changed in your perspective with improvements. Besides I am tired of spilling oil at 48 bucks a gallon. Besides, case in point, the jet engine was trashed for being to complex, unreliable, and using too much fuel many years ago. Seems to me the Verado was just an early experiment, and is the case most times it did more for research and developement than the poor guys who bought them. I like the idea but even with it being a Yamahoppy might just wait two years before I sunk the cash in one... Just my thoughts..

[Larson15]

Maybe its a hybrid

[mrfish1991]

^^lol

[CaptZ21]

Did he say hybrid or ricebred?

[mrfish1991]

I thought i saw a big wing on the back of the motor from the teaser vid. so maybe it is a ricebred...lol jk

not doggin on yamaha, i think it is the only brand to go with. and I am very interested in how they got the new proformance.

[Black_Bay]

Someplace else a guy brought up the 2010 Yamaha FX SHO, which is a 1.8 liter supercharged 4 cyl. Something to ponder.

Someplace else a guy brought up the 2010 Yamaha FX SHO, which is a 1.8 liter supercharged 4 cyl. Something to ponder.

If it's a 1.8L it could very well be the motor that was used in the newer Toyota Celica's. That motor that is used in the Toyota Celica is also used in the Lotus Exige also.

[chippy]

Here's my speculation.. I believe it is the 1.8L used in the Toyota Celica (Yamaha built), also I think it's the same motor that is used in their New Waverunner lines.

This is straight from Yamaha (waverunner page):

SUPERCHARGED SUPER HIGH OUTPUT ENGINE

Yamaha’s 1.8 liter, Supercharged, Super High Output engine is the largest ever in a PWC and 300cc’s larger than any other model. Compact and lightweight, it’s also 45 pounds lighter and packed with power to provide the best acceleration and top speed ever offered in a WaveRunner. Earning a 3-star low-emission rating, it is also the only engine in its category optimized to run on the least expensive regular unleaded fuel.

and to add to the those interested:

Yamaha SHO™ Engine. A 1.8L 1812cc engine that accelerates quicker from 0-30 than a Corvette ZO6

[Cecil]

That looks like it could be it...

[Central Bassman]

I can't wait for it to come out with all the details...

[ikeslayer]

wher is this video

[Jig Master]

This will be the best motor out there hands down.

[Larson15]

I cant wait to see what the price tag will be.....we should take bets

[TR21]

I'm sure you're looking at 20K plus. Although it seems Yamaha will be teaming this with a new redesigned Skeeter ZX model and releasing it on the same date. A friend of mine works for Yamahas research and development and this is about all he can say without losing his job - very hush hush. On a side note, It's not turbo or supercharged - new high rev technology. Supposed to be the same weight or slightly less than the 250 hp Series 2 HPDI with the same top end but a lot quicker hole shot.

[JohnMickish]

The new motor will be price at $500-$1000 more than a current HPDI. Not at all out of the price range for a guy in this market. The new motor is 4.2 liters, the 250 weighs in at 505 lbs, the same as the opti and less than the current HPDI and Etec.

There is a ton of leaked info out there on this motor if you know where to look, and it's not on the yamaha HSOforum. Same fuel consumption as a 250ProXS, less emissions than an Etec, better acceloration, easy oil changes and the same money. What more could a guy ask for?

There is a thread on this motor in the Boats and Motors section with some more info than is listed here.

Yamaha Unveils ''Revolutionary'' New Outboards in Chattanooga

posted November 16, 2009

Late Monday Yamaha Marine Group came to Chattanooga to announce the biggest product launch in the company’s history. The launch includes nine new outboards that officials say "reach new levels of reliability and overall customer satisfaction."

“Customer satisfaction is a moving target,” said Phil Dyskow, President, Yamaha Marine Group. “It includes expectations about power, performance and comfort – issues such as sound level and vibration – and, of course, the reliability of the outboard. A brand that wants to be on the top in customer satisfaction can’t ignore any aspect of the product. Consumers want it all, and we have to deliver.”

New Materials and Processes

Yamaha says it has applied innovative uses of materials and processes and taken a fresh approach to designing its new generation of outboards. The new generation includes the VMAX® SHO™ 250, 225 and 200; the new F300, F250 and F225 V6 offshore outboards; the new F6 and F4 portables; and the new mid-range F70.

The outboards feature reduction in weight through the use of new materials, and by a powerhead-engineering approach that seeks to gain the highest power output consistent with excellent long-term reliability.

Four Strokes that Run Like Two Strokes

At the top of the list of customer satisfying innovations is a family of four stokes that can outperform the best two strokes. Yamaha’s new VMAX® SHO™ outboards are as light or lighter than competing two strokes and deliver better hole shot and time to plane than Yamaha’s two-stroke VMAX® Series 2 outboards. Now anglers can enjoy the traditional virtues of the two stroke -- light weight and acceleration – with the virtues of a four stoke – clean, reliable, quiet operation. The VMAX® SHO™ is nothing short of a revolution for anglers.

Volumetric Efficiency

One thing that characterizes all the new outboard powerheads in the Yamaha line is volumetric efficiency. That means each outboard gets as much fuel and air into the cylinder as possible, which has a positive effect on power and overall fuel economy.

The F300/F250/F225 family of outboards has an amazing 4.2 liters of displacement and uses a larger throttle valve. Inside, the new V6 powerhead has larger intake and exhaust valves. In addition, it uses both longer and larger intake tracks. Variable camshaft timing is also employed (and is new to the F225 and F200). All these features increase volumetric efficiency in the 4.2-liter V6s.

The Yamaha F70 uses a unique four-valve-per-cylinder head design in which the valves are actuated by a single camshaft instead of the more typical two-camshaft design. This highly unusual design not only allows greater intake and exhaust valve area – which contributes to volumetric efficiency – it also reduces the weight and parasitic losses that would result from using two camshafts instead of just one.

Reducing the Weight

Very seldom in engineering does adding one material to another result in decreased weight and increased efficiency, but that’s what one new process does in both the Yamaha VMAX® SHO™ and the new F300/F250/F225 V6 offshore family of outboards. The powerheads of these outboards use plasma fused sleeveless cylinders instead of a steel sleeve.

Not only does the process reduce the overall amount of powerhead weight, the resulting material – which measures about 0.1 mm thick – takes up less space in the engine block than a conventional steel sleeve, which means there’s more room for the pistons themselves. It is in this way that displacement has been optimized in the new 4.2-liter powerhead. The process has allowed Yamaha engineers to gain the greatest displacement from the least amount of mass in the engine block, which also reduces overall weight.

In addition, the micro-textured cylinder walls that result from the process create less friction, allowing the pistons to move more freely, thus reducing parasitic losses from friction.

Yamaha officials will showing off their new engines on the water at their testing facility in Bridgeport, Ala. Tueday morning.

Profiles of New Yamaha Outboards

Inshore, Offshore, Bass, Portable, Mid-Range: Something for Every Boater

The Game Changer: Four-Stroke V6 VMAX® SHO™

A revolutionary four-stroke outboard, the VMAX® SHO™ takes power to a whole new level within the bass fishing realm. It is noticeably faster out of the hole and to plane than the VMAX® Series 2 and has a broader power curve for smoother acceleration and performance. It also achieves higher speed over a measured distance and provides the best acceleration of the outboards in its class. Indeed, the VMAX® SHO™ is the lightest outboard in its class when compared to two-stroke competitors using filled reserve oil tanks. The VMAX® SHO™ family is comprised of 250, 225 and 200 horsepower versions.

The Versatile Performer: Yamaha’s New Four-Stroke F70

Yamaha’s all-new four-stroke F70 outboard is so light and versatile it can even be used in applications formerly reserved for some two-stoke outboards. Delivering an impressively high level of performance for its size, the F70 is a great lightweight alternative for aluminum fishing boats and has the best horsepower-per-liter ratio in its class, weighing 109 pounds less than Yamaha’s four-stoke F75. The F70 can be equipped with the Yamaha Multi-Function tiller handle and Command Link® gauges. It also has a handsomely designed compact exterior that gives it a family resemblance to Yamaha’s newer outboards.

The Truly Portable: Yamaha’s New Four-Stroke F6 and F4

Yamaha’s two new four-stroke portable outboards, the F6 and F4, weigh only 60 pounds (for the 15-inch shaft model) and with convenient built-in carrying handles – living up to the name, they are truly portable. The new F6 is 23 pounds lighter than the former F6, which makes it easier to handle and install. These outboards can easily go from the pickup bed of a truck or the trunk of a car to the transom in very little time, and they are powerful.

The Next Generation of Offshore Power: Yamaha’s New V6 Four-Strokes

Yamaha’s new offshore V6 four-strokes represent a new generation of offshore outboards designed to carry on Yamaha’s reputation for reliability, offering class-leading performance, the latest in innovation and technology. This new family of four-stroke offshore outboards has less weight than the previous generation. It also has everything else it takes to satisfy offshore fisherman and boaters. These new outboards are best-in-class in many measures.

The new family of outboards is compatible with the new Command Link® Plus. Command Link® Plus uses a unique 5-inch single LCD display that is the same height as the current Command Link® square gauge to make optimum use of space. Designed for configuration by the user, it has many display options for the outboard and the boat. In addition to speed, the LCD screen can display oil/water pressure, charge level, rpm, etc. It can also display fuel flow rate, tank levels, water temperature and water depth. It operates with single, twin or triple applications. (Quad applications require two displays.)

The Powerful F350: Now Equipped with Command Link® Plus

The new F350, the jewel in Yamaha’s offshore crown, is now compatible with Yamaha’s new Command Link® Plus, the latest generation of Command Link® that allows for expansion on the current menu of capabilities. The ultimate outboard is now equipped with the ultimate electronic system.

A Great Repower Solution: Yamaha’s Venerable F250

Due to popular demand, Yamaha is bringing back the venerable F250 “Mechanical Shift” as a solution for boaters who wish to repower without upgrading to a later electronic control box. Offering a great solution for boaters who are satisfied with their boats but simply want a new outboard, the F250 “Mechanical Shift” is the perfect replacement. The F250 is compatible only with cable-type control boxes. At the same time, it has the ability to use Command Link® electronic gauges. With the use of a gateway, it can also operate with NMEA-2000® compatible displays.

This will be great if the published weights are accurate, but Yamaha doesn't have the best record for giving real weights(with their snowmobiles anyway). I had a Yamaha 225 four stroke for a few years, and it was flawless. The only things I didn't like about it were when coming off plane because it was such a tank it would darn near swamp my boat without wave wackers, and it was also pig out of the hole. I hope it turns out to be a great motor for them, I may switch back to Yamaha if they work out, but I will give them a couple of years to work any bugs out first.

[Cecil]

Does anyone here own a Series 2? How are they? Any problems? Holeshot?

[TR21]

Cecil,

A friend of mine has a 200 on his 20i Skeeter and loves it. I've ridden in it a few times and he has had zero problems, holeshot is great, great top end and not too thirsty. A lot has to do with the boat design of course but overall a really nice motor.

[TonkaBass]

I talked to a guy who runs a 250 series 2 and said it was slower on top end and more doggy than his old HPDI...

[Cecil]

what year was his old one?

[TonkaBass]

Not sure..

[Cecil]

our old HPDI was pretty sluggish, but it was the 2.7L...
