Not sure if anyone has seen this yet, but it's neat to see some aftermarket add ons for outboards. Wonder how this would compare to the new 400R??

[Mr. Demeanor]

VERY cool!

[JPEROG]

Here comes the future... (Merc. market competition) I hope that yamaha comes up with a case and gear that will make these an option. I would consider having a pair of them on a midsize cat if the parts were available. I know that Jason Wolf loves his yamaha but is limited by the case and gear. I had yellow blood flowing thru my veins up until 1985 when they made the YZs white and have had several FZ 5 valve per cylinder bikes (always loved their products).

That thing will need a gearbox bigger than a 400 merc?
I think the future will be following the seven marine idea with shift above the box and twin pinion

900 HP hanging off the stern of a Silverwing? Cant think of anything smaller/faster that would float twins. Maybe one of the new Talons?

[whipper]

Yes cool. I went to there web site seems those clips were from 2014? I love the idea and its just a matter of when not if these days. Look at CRt motors. Personally they appeal to me more than any motor on the market today. :cheers: The Super Charger whine is very cool sounding on an outboard though !!!

I am a dealer for Magnason and we love the TVS..we've made 700plus rwhp with that blower and harrop is a Sharp group...

The pull would be incredible on an LCB, a 24 & 28 skater, or a Doug Wright 28. Are they adapting sportmasters to them? What rpm to they twist them at? and what is the cost for the kit and mapping?

No lack of innovation from the folks down in Oz. Cool piece of tech for sure.

Ive been looking at Magnason blowers for my 6 liter Hummer H2. Got anything in the scratch and dent pile ?

i think you need 400r cases with that much torque. dw 28 with those would be crazy

[joneill]

Looks and sounds cool, have to get Superbender to get one for his! :D

[Mr. Demeanor]

Need to cut two cylinders off so I can get one :-)

I emailed and got a response. Asked them to comment here.

[joneill]

Any idea on a cost? I didn't see anything on their website,

[ghost28]

wheres superbender????? I think they need him for torture testing of these.....:iagree:

[DoktorC]

Now we just have to get the oil sump out of the mid and into a remote tank and we can do a 15". That is a slick system...

[powerabout]

with all this 4 stroke complication and weight they should invent 2 strokes

[FMP]

What's the total weight of all this 500hp , 550 lbs for a 20"?

[2.5-21]

scribed!

[FMP]

If you turned it up would the block crank rods pistons take it?

[Mr. Demeanor]

If you turned it up would the block crank rods pistons take it? No but thats not the point LOL :leaving:

[JPEROG]

I had an RX1 (1000cc snowmobile motor that was based off of the R1 sport bike) and it was set up for 30 Lbs of boost on a stock lower end. The sled made around 550 hp so being that this is a 4200cc motor I am guessing that 700 hp would be an easy target. One thing about the sled is that you didn't keep it under load for very long-it was incredibly fast. https://www.youtube.com/watch?v=kJxmWkX5KU8

[FMP]

No but thats not the point LOL :leaving:

You know how it is, today it's enough but tomorrow you need more

[powerabout]

Boat engines have a harder duty cycle than just about anything hence you are not going to find big hp/ci in this field compared to others.

[FMP]

I'll take that as a yes to turn it up to 11

Maybe we could go back to carbs and breaker points too!! 40:1 premix like 1972....

Hey i premix 40/1 and mines a 96. Oh wait I chose to do that. Never mind. LOL:rolleyes:

Heres the email response I recieved from Nizpro:

Hello Christopher

Firstly, thanks for your interest and posting links of our Supercharger kit for the V6 4.2 Litre Yamaha kit.

I have now read the comments posted on the links you provided, so I now have some idea of the questions forum readers would like answered.
We have a company policy of not directly adding comments on public forums, as it becomes impossible time wise to answer individual questions on multiple forum sites along with not wanting to tread on forum advertisers toes. I am happy for you to repost my answers to your email questions if you believe it to be appropriate.

Below seem to be the most common asked questions.

April fool’s joke? No it certainly is not, this is the real deal. We were certainly a little amused when it became public on April 1st in the US (April 2nd here in Aus)

Does the standard engine cowl Fit? Yes the cowl remains 100 % untouched, we do add a 104 mm { 4 inch approx. } spacer that is attached to the standard cowls internal latch points, the standard latches are then bolted to the spacer. The cowl then simple goes on in the standard manner.

Which Yamaha model does the Nizpro Supercharger kit fit? Our Supercharger kit fits all F series 225, 250 and 300 V6 4.2 litre models. It also fits all 200, 225 and 250 SHO V6 4.2 litre
Models

Is reliability and durability compromised by adding a supercharger to a naturally aspirated engine? Firstly let me say that the 4.2 Yamaha V6 is an amazingly well engineered product. Any owner of one can be assured just how good these engines really are and how under stressed they are in standard form. In its highest production level { 300 HP } it’s making a mere 71 hp per litre at a lazy 6000 rpm maximum engine speed limit..

Countless production engines are now found in both naturally aspirated and forced induction derivatives with very few and in some cases no internal mechanical changes. When changes are made they often consist of a simple static compression ratio change.
If very high outputs are required you may find differences in connecting rods, the addition of piston that have pressure feed oil cooling and possibly different exhaust valve material in turbocharged engines.

The standard 4.2l V6 Yamaha is engineered as standard with high quality connecting rods, oil cooled pistons and a compression ratio that is low enough to suit forced induction. So it is a brilliant platform for forced induction.

In terms of power output per litre the closest current example is the Mercury 400R at 2.6 litres it’s producing 153 hp per litre, over twice that of the 300 HP Yamaha in standard form. It does this at 7000 rpm some 16 % higher than the Yamahas 6000 rpm and with approximately 2.2bar absolute boost pressure being applied. Don’t forget the supercharger requires crankshaft horse power to drive it. This could be in the order of 50 to 70 horse power. So what is being measured at the prop shaft is not what is being generated at the crankshaft. In truth the 400R is now producing in the order of 173 hp per litre. This alone shows just what an amazing job Mercury have done with the Verado 400R especially considering the duty cycle marine engines are operated in.

Getting back to the Nizpro Supercharged Yamaha, it is now producing 107 hp per litre or approximately 115hp per litre accounting for the drive requirement of the supercharger. This is 50% less power per litre than the 400R at 600 rpm less. With approximately .7 bar less absolute boost pressure.

Now it’s hard to argue that given two identical engines one producing 300 hp and the other 600 hp that the durability will be the same at peak power. However given that very few people even in a marine application will hold their engines a 100% of the time at peak power, rpm and load for the entire life of the engine, this story of durability starts to change.
The higher power engine if prop’d accordingly will now achieve the same cruising speed at lower engine rpm, this in effect will prolong engine parts given their slower rotational speeds. Think of this a little like a low speed diesel engine {Truck}vs. a high speed petrol engine. {Car}

We started this project in 2013 and to accelerate our own durability testing program we are running our pre-production tests at well beyond the 450hp power level, Higher rpm with substantially higher boost pressures than what the production 450hp package will be released with. Up to date we have seen zero failures of any kind using a standard Yamaha 4.2 V6 engine.


Lower Unit strength? Currently we have seen zero lower unit gear failures. We certainly understand that at some point the lower unit will become an issue and are already taking steps to be able to offer upgrades.

What does the supercharger package include? This is the short list not including clamps, nuts and bolts. etc.
· Nizpro Supercharger unit
· Twin water to air intercoolers
· Moulded intercooler hoses
· Intercooler water outlet fitting
· Intercooler Water pick up

Price and availability.
The official release will be at the Sema Show in Las Vegas on October 31st 2017.
Over the next couple of months we will be looking for the premium dealers around the world to install, service and carry stock of the Nizpro Supercharger upgrade packages.
Prior to the release we will be offering a very limited quantity of kits to selected dealers to be installed on boats for display purposes.
Supercharger packages ordered prior to the official release will be $9995 Usd + shipping and import taxes.

Due to being inundated with emails I have yet been able to reply to all of you, please allow me a little time for my reply.

[Jamescole]

250 SHO is 505Lbs
300HPDI is 535Lbs

so lets assume 75Lbs for the kit ?

Game changer.

[FMP]

Heavy but dialed up a bit more or as , really strong.

[Capt.Insane-o]

7psi of boost instead of 20+? Gimmie. The news of this has been rumbling around the back waters for a little while now.

[FMP]

11psi

[Mr. Demeanor]

I received some more info from Simon at Nizpro who asked me to pass it along.

Received another email that addresses some of your questions.


I see there are a number of new questions and maybe one I have missed. If you would like to copy and paste the below answer please do so.


• You can start with any hp derivative 4.2 V6 Yamaha, 200 through to 300, in all cases power ends up at 450 hp. So guys wanting to purchase new engines please start with the 200 as they are less expensive than a 300 and the cost savings can go towards the Nizpro Supercharger kit.


• Perfered and recommended fuel is US 95 however 91 can be used with a slight power drop.


• The engine re calibrations contains modified Variable Cam Timing { VCT } to suit the Supercharger requirements.


• We currently have a local emmisions engineer setting up a testing procedure that and will be in discussion with the nessasary authorities for CARB compliance. Since 1996 all our aftermarket vehicle products and been tested and passed local required emission regulations. We take this aspect very seriously.

For the first time in ages, I stayed away from S&F for a whole week, and then this pops up.

Awesome!

They use a Roots style supercharger rather than the Lysholm style that Mercury uses for the Verado...
