350 Suzuki has been announced

[Risco]

4.4l engine twin roating props lower unit big outboards are here and it's beautiful thing get weight down some would be even better. http://www.tradeonlytoday.com/2017/06/suzuki-unveils-new-350-hp-outboard/

[mach351]

4.4L, no boost, and 12:1 compression - woah

[Hot Shot Merc]

attachments don't work for me?

[mach351]

They didn't work for me either Rob.....just google search it and you'll find it

[Risco]

Sorry here try this. http://www.tradeonlytoday.com/2017/06/suzuki-unveils-new-350-hp-outboard/

[JPEROG]

They used their heads and kept them narrow enough to mount at 26 on center. Thats a big deal for v-bottom center consoles.

[powerabout]

is there reduction/stepup under the powerhead as well like a Yam 350?
yes

"Like Suzuki’s other V6 outboards, the DF350A features Suzuki’s offset driveshaft engine layout, which allows for a more compact outboard and two-stage gear reduction. Two-stage gear reduction provides a larger reduction gear ratio (2.29:1) and more torque for quick acceleration, and improvements in top speed, as well. (It is worth noting that the DF350A can be mounted 27-inches on center, so it will fit on more transoms, and take up less space in twin, triple and quad installations.)"

got to be the way forward to remove some torque from the lower unit and maybe lift the powerhead and swap the gears in 5 minutes.
Manufacturer only need one gearbox in stock to suit whole range of engines, twin prop as well
where are you Merc? ( 6 gears in the lower unit not cheap)

[FUJIMO]

The torque reduction allowed smaller gearcase gears & shafting, less gearcase load, thus a smaller gearcase design, which negates the need for swinging large wheels. They have a large selection(read: many pitch sizes)of stainless props to compliment any boat design or size or speed for the new DF350A. The 55 degree V-block was the very first design decision, to allow current owners to repower effortlessly, which sells more outboards.

[XstreamVking]

Suzuki just does what it wants and quietly goes about it's business. Some of my guide buddies run zuki's and have had great results.

[racer]

I wonder how much power is lost going thru that many gears.

[flabum1017]

I wonder how much power is lost going thru that many gears.


I would think any loss would be countered by less slip from the dual props...........

[FUJIMO]

I would think any loss would be countered by less slip from the dual props...........
...and the many other new engineering design advantages they've introduced on this engine.

[FUJIMO]

If anyone would know...Seven Marine could tell you...

[powerabout]

I guess in forward the gears dont move
The dog joins the shafts together
In reverse it pulls top shaft to gear and also bottom shaft to the other gear??
Maybe 2 dogs?
Join together for forward
Move apart for reverse and grab the gears?

All they did was move the clutch dog from the prop shaft to the drive shaft. It's set up normally except the forward and reverse gears are on the drive shaft. The bottom gears only drive the prop shafts.

[whipper]

i like the water pickup in the skeg thats a great idea for high prop shaft heights. 550-600lbs? Be nice to see a 350hp under 400lbs sooner than later. The car engines are getting that way but it seem the outboard manufacturers think heavy is better for some reason? the 300xs is 505 at around 350 with the DBR stage 1 kit is that the best power to weight other than the new CRT motor thats under 400lbs 350hp ++? Not sure im to exited about any motor made today thats over 500lbs. Just seems like a waist of power if you cant get the weight down? the Suzuki motor looks great though I love the cowl!!

[whipper]

Oh snap just found it 700+ lbs!!!! Come on whats the problem with these guys these days!! 700lbs only 350 hp is a dog. Thats horrible power to weight ratio!! It needs to be 500 hp to be a contender on water at that weight. Thats like a fat guy with skinny legs. Hydrodynamics needs less drag not more to be efficient! Oh well just another boat anchor as far as im concerned. Id put twin DBR 300xs motors against twin Suzuki 350,s on the same pontoon boat any day of the week. At 400lbs lighter should smoke those! And after new 300xs motors and DBR mods about 10 grand less per motor. The 350 is the same price as the 400R or pretty close anyway at 32000 !!! Thats alot of coin for only 350 hp for any motor with that few HP. My 225 has 240 so only 100 hp shy and is 350lbs and worth about $4000 haha

[H2OPERF]

Interesting shift design, less torque thru the clutch dog but more rpm. that will probably be a nightmare to shim with that idler gear and all. Dave

[racer]

Looking at the shift appears when in forward the clutch is down and runs straight thru with upper gears along for the ride but when dog moves up it reverses rotation so not loosing much when in forward.

[Smoking Joe]

That looks way better than in white.

[RSWORDS]

Wonder if this dual prop will catch on better then it did with Yamaha when they tried the TRP 150s.

[Ted Stryker]

I'll order mine with a self-deploying marker bouy so I'll know it's whereabouts when it breaks the transom off

[Krazymaan]

Ya but holy crap 750lbs each, My 2.4 powerhead only weighs 153lbs. I don't think you will ever get these beasts on any boat under 20' long legally. I for see a lot of warranty repairs with that intake/injectors/12:1 set up.

[powerabout]

Still room for 4.4 ltr 400hp etec v8

[mach351]

Lmao. Y'all are still living in a fantasy world that manufacturers give a rats a$$ about our kind of boats. They don't. Period. There is no money to be made on our tiny segment of the boating population. If you're waiting for lightweight two strokes, guess what, you're gunna be waiting forever. The 300xs's days are numbered I assure you. And watch.....Suzuki will sell a ton of these motors to the fishing guys....two, three, and four at a time.

[Risco]

Still room for 4.4 ltr 400hp etec v8
Yeah I don't see why they haven't done it already would be 4.5l of beast mode

[flabum1017]

The 350 Yammi weighs more...... As said, these Suzuki's are for the big boat market..... no 20" versions or race versions ..........

[SANTAFE]

So is a Suzuki a better engine than a Yamaha? Lighter, more powerful, more dependable, better mileage, more cost effective? I am just curious. Is it just a matter of personal preference (Ford-Chevy)?

[Ted Stryker]

Based on my searches Suzuki these days is certainly holding their own, and I'd be just as confident with a newer suzi as I would any other brand.. my disclaimer is I've never owned a four stroke outboatd but I've read much as I can find and searched all the reviews that I can find that seem to be from people of knowledge.. I think they make some four strokes for mercury AND jonnyrude, so that at least holds some merit.

[XstreamVking]

I would buy a zuki way before I would buy a yammi. My guide buddies that run the zuki's swear by them. Yammi guys swear at them....I have always liked the zukis, I had an 85 hp zuki on a 15 whaler in the 80's and it was a real surpise. Nice power, slick shifting, good on gas. Not a top end motor, but was smooooth.

[RSWORDS]

The only thing we see with Suzukis are that they feel a bit under powered compared to the same HP as the competition and we are starting to see ALOT of internal rot/corrosion issue in motors around 10 years old, mostly the heads. It is almost as bad as the Honda's.

With that said, it is rare one will leave a person on the wrong end of a tow rope.

any opinions on the most corrosion resistant? It's a non issue in my freshwater world but just curious

[RSWORDS]

Mercury hands down right now. Yamaha (if you take the exhaust corrosion the f225s and f250 Yamahas had 03-07ish) is a close second.

It's hard to tell though​ because it takes 10 years for it to show it's head. The current models could be the complete opposite In 10 more years.

Again, this is just what I see in my shop in this little part of the world.

[flabum1017]

Suzuki's are cheaper than Yammi's too. But since this 350 is a new model, we'd have to wait and see what kind of catastrophic failures it has like the Yammi's and Verados.......

[Scream And Fly]

That's what I was thinking - 750 pounds. I realize this is a large outboard, meant for large boats, but these things just keep getting heavier and heavier. It is a very interesting engine though, and I always like to see that innovation with outboards is still going strong, though.

[powerabout]

does it have inbuilt power steering, joystick controls etc to compete with a merc?

[Markus]

Wonder if this dual prop will catch on better then it did with Yamaha when they tried the TRP 150s.

The Yamahas became redundant when the limit for tournament bass engines was increased from 150hp to 225hp, from what I remember.

[Deznuts3570]

Ive run zukis 4 strokes since 01. Killer motors! Had a little 50 that finally died a couple years ago from 01. Cant tell you how much beating we did to that thing. Running 2 different 115s, one brand new and one older. I think the brand new 115 is just as cheap on fuel as my 50 was in 01 lol. Its honestly stunning how cheap it is on fuel! 4 strokes, ill run zukis all day. 2 strokes, mercury all day
