CORRECTION: The maximum speed for the Axopar 37 with twin Mercury 300hp V8s should be 47.4 knots.
Nope, 49 knots
@@mesalim2505 Thank you , both. But, now i think, that This Is the Real Deal !!! ! !!! Thanks again.
And then you combine it with a sharrow prop
I ran the numbers in comparison to a Yamaha F300 and Merc Verado 300. You break even on the cost difference in fuel savings at about 1800 hours. (diesels cost quite a bit more. $60k compared to $28k).
However the gas outboards are good for approximately 4000 hours. Manufacturer claims the diesels are good for 10,000 hours
Over the life of the diesel you save $147k in fuel, and save having to buy a second gas engine over 10,000 hours.
That's nuts. if they can get the service network right and run with minimal problems over their life... SIGN ME UP!
Very interesting video Jack, absolutely fascinating.
An equally useful comparison would be between these two Cox diesel outboards, and a pair of equivalent Volvo Penta D6 inboards, and it would be interesting to see how they compare in performance, consumption, price, etc.
VP diesels can be fixed anywhere in the world, but marina engineers would be unfamiliar with Cox, so that would be a big no from me.
I don't know why anyone in the UK or Europe would want petrol sloshing around in the tanks when diesel is ubiquitous, cheaper, and goes way further.
And diesel doesn't go kerboom when the fumes catch alight.
The figures show why all the big boats use diesel not petrol/gasoline. It costs less and you go further.
For me, equally important, is you cannot get petrol at every marina. Diesel, that you get _everywhere._
And because I can't help it, it looks like we're all going to get to love Cox. And those are some big, powerful, no-nonsense Cox that just love to get stuck in and keep on going. Cox that deserve a bit of respect.
OK OK I'll get me coat... :-/
@@darthkek1953 good smut there! 👍
I thot it was deisal doesn't light on fire as easy
deesel don't go BOOM as easily as PETROL (gas) either!!!! MUCH SAFER from that standpoint
the big boats run bunker oil which is the bi product of making diesel its even cheaper
Been waiting for a CXO300 review, awesome performance
Impressive performance!
These things are fantastic. 30% fuel efficiency is quite alot when you consider the Amount of fuel outboards guzzle. People might say about the weight but the performance is enough that the weight is not much of a consideration. It's like weight difference of one not so fit guy (the average joe) for two engines. Much less than the extra fuel. What I find impressive is it's top end performance. I though would like to see some independent reviews on the performance and durability. Also, I do wonder how the low rpm will hold up on high speed craft. Those do favor higher rpms as the props to tend to break contact with the water often and face alot more cavitation.
Hiya, I think the weight difference is 116 kg per engine. I read your comment as 116 per engine, which I think is an error. 232 is a very unfit guy :)
Don’t see why not there are diesel offshore powerboats and have been for years and diesel rally cars
Torque helps in such scenarios. Win for the diesel for sure.
@@darrenjones3681 rally trucks*
These things are about 3 times the price of a similar 300 Yamaha. You'll never make that up in fuel economy or price, and the supercharged Mercury outboards have just as much torque and are much faster and much cheaper
It would be fun to compare this with OXE 300 turbo diesel. 3 liter Inline six, 300 hp.
Been 5 years of them saying they are for sale, but I'm yet to get them to give me a price delivered to Vancouver Canada
Wow those are impressive figures 👍🇬🇧❤️
Best way to prove it's reliability is in offshore powerboat racing like the Cowes to Torquay race or other powerboat racing regattas!
they are not very reliable. they keep blowing up the gearboxes. I work in Lymington and the engineers are always changing the gearboxes they say they have about 40 to rebuild back at the workshop.
Not surprising to me. Diesels are torque monsters anyway, so I would actually expect the gears/transmission to go out before the engine. Not me very familiar with what is more expensive to replace an engine block or gear/transmission?

Another thing they could do to make the gearbox/transmission last longer is beef up the gears or create a hybrid dog clutch gear system . Might be a little rough in the shifting, but will definitely last.
Wondering how the difference in torque feels. I especially like the Axopar 37. I live in Florida so air conditioning would be convenient.
I can see an diesel advantage in some areas and when used on yachts and ships but the dealership network will be thin and will severely hold back the distribution. Cars and small trucks are going electric bc diesel seems to be becoming less in favor bc of emissions and all that business.
The top of the outboard pyramid is Yamaha and Mercury. Yamaha is still producing reliable but older style engines, Mercury has jumped out of the box and going full speed ahead with he latest and greatest designs and modern engineering technology is proving them to on target of style, reliability and performance. Suzuki’s have always been excellent motors but they lack the dealership network and warranty responsibility. I turned 75 today and have been a boater for 65 years. I’m glad to see boating finally take such wonderful leaps.
Nothing to say about Honda outboards ?
Sharrow marine has a toroidal propeller that may bring more fuel savings and a slight performance boost.
That's me to a T. Love a big petrol BUT... diesels are in my heart. Would be very happy with a pair of them. Oh, and I hate outdrives, the work of the Devil.
the biggest benefit these will have is for when the boat they're installed on is used as a tender for a super yacht and then both boats would run off of diesel and no need for Aux Gasoline tanks onboard the super yacht. Which involves headaches and a level of danger vs diesel.
That would be amazing, infinite range for the tender
Not true. Here in Scandinavia and I know that is also the case in Australia, not every fuel dock has petrol (gas to you). But all have diesel, making it a much longer range boat than the improved efficiency suggests.
@@NBM397 What’s not true?
hope to own that one someday here in philippines
Boating is a different world. Thats considered fuel efficient. That's a lot of money to travel just over thirty mph.
46kts is 53mph.
That's good figures. Bigger boats are measured by gallons per mile
It’s many many equivalent pickup trucks weight and pushing it through water it takes a lot
of power
To check how much money on fuel you can save is a complicated task with many variables. Estimates range on 50 to 100 hours per year on a yacht, obviously this can be more or less. But let us go with just 50 hours a year. One hour per week. That's not much. Fuel prices vary, we'll go with Shepperton as they came up first in the search engine. Round figures, 60/40 Diesel £1.30 and Petrol £1.70; the fast cruising speeds came in at 60 litres/hour Diesel, 93 litres/hour Petrol. Again, rough figures £4k Diesel, £8k Petrol. So at a fast cruise the Diesel engines save £4,000 every 50 hours of use.
What if you do lower speeds for fuel efficiency? Okay, but then presumably as you take longer you're on the water for longer because you take more time to get to a destination. To go the same distance as Cruising speed in Eco takes 4 times longer, so let's look at 200 hours for a fair basis of comparison. Diesel comes out at £2,100 in cost, Petrol is £6,000. Again a £4k Diesel saving.
Obviously if you only use your boat for a very few hours per year the savings won't add up, but the more hours you do the more it adds up, and certainly by a few tens of hours per year it starts to add up substantially.
Thanks for doing the math
With the pricing roughly £16,000 more for a diesel you need a lot of hours to be even with a petrol one.
If you considering the prices for a fuel in average EU country (1,6 Eur gas/1,4 Eur diesel) or even in the US math is even worse
Not to forget maintenance of a diesel is more expensive than a petrol
@@altergreenhorn where did you get your prices? You're not using road fuel prices are you? A link would be welcome.
You say it's even worse for the US. Again, are you using ROAD fuel prices? Marine prices are a different beast. Example, Alligator Point, FL diesel $2.7, gas $3.9; Suwannee, FL diesel $2.8, gas $4; Panama City, FL diesel $3.6, gas $4.6, and so on and so on and so on, dozens and dozens of marinas and it's a consistent prices difference. So a bit of boating and the costs will MASSIVELY stack up, as my figures show.
As I say, links to your EU marine fuel sources would be welcome.
Besides, MB&Y is a UK publication, we have to pay UK rates not "average EU" rates. The reality is if you do a bit of boating in the UK, or the US, you'll quickly make a saving.
Also: diesel engines cost more to service over a life than petrol? Until this point in my life literally everyone I have ever heard say the opposite (gas engines need more frequent rebuilds). If you can reliably source your argument I would be grateful.
If they can get distribution and service right, they may just have a contender. That could be quite the furl savings for someone who does a fair bit of cruising. What about price comparison to a petrol engine. I’m sure the diesels will be more expensive, but by how much?
I believe the diesel is about 30% more expensive than the Mercury. Not 100% sure since I don’t know exact UK pricing.
Out of curiosity what app were you using to monitor fuel consumption?
My volvo d4 motors (x2)move my 5 tone 30 ft boat 20 knots 42 liters an hour combined for cheaper than those outboards, and I can do over 30 knots
4 cylinder against 8 cylinder -
@@lameduck3630 there is that, but also my volvos have duel prop legs, upto 30% more efficient than single prop legs, but they are over 10k a leg and 3500 per prop set
Interesting to be sure, however, Volvo Penta makes a 300hp diesel (albeit not a outboard) but VP’s diesels are 3.7 litre inline 4s and with their new DPI drive, there is no need to shift in and out of gear while low speed manoeuvring in the marina.
The D4 is a really heavy engine.
Opps you did it again no link ink the description For the rib outboard test as stated
This just proves what has been happening for years, put the word boat in and that will double the price, I do not understand how any engine could or should be more expensive that an entire car? a complete articulated truck unit is less expensive than these and many other outboard motors????????
Production volume. Economies of scale.
BTW, if you can get me a new articulated truck for that money, let me know.
Soon as they launch the 37xc with these from the factory i'm in.
buy it
Did the Axopar need a different fuel inlet for the tank and is the diesel ok thru standard diameter fuel lines that would be fitted for the petrol outboards ? I think the biggest advantage would be the greater endurance gained for serious cruising.
I would have liked to seen noise readings in decibels listed showing a comparison between the Yamaha and the Cox at various speeds both inside the cabin and outside. I had twin Yamaha 250's om my boat and they were pretty noisy when you sat outside at cruising speed. Just saying they are a little more noisy doesn't give your audience any solid information,
Very interesting but I am not sure the figures would add up for day and coastal cruising. I could see the benefit for commercial vessels doing long hours.
I made full post in this thread about costs. If doing typical pleasure use (50 hours, cruising) the fuel saving looks to be about £4k a year. The Diesel is using 1/3 less fuel than Petrol but at the marina I based prices on cost about 1/3 more. That'll rapidly add up if you're doing even not very many hours per year... boats burn a LOT of fuel.
These engines (and the swedish competitors) were developed because of the nato single fuel policy. Petrol will go away on nato bases and warships.
I’d like to see this with one of those Sharrow propeller. For some reason I just feel like those wimpy 3 blades are not transferring all that diesel torque to water making them less efficient.
#propslip
Very big difference in fuel consumption also.
Cox, I remember my model airplane being made by Cox.
Keil Kraft?
How would 1 Mercury 600 V12 perform on the Axo 37 in comparison?
One outboard is better than two half's.
There is a 13 percent loss in friction with two outboards.
One 600hp will have the same top speed as two 325hp.
$62k USD each? I don't see them selling many of these in the U.S. where fuel is still relatively cheap. That's about 125% more than the Verado upfront for about a 25% efficiency advantage.
I am not looking into these due to saving money, but because I want an Axopar or equivalent, and I want as much range as I can get (I like to go on adventures). The other alternative is a slower inboard cabin cruiser, but I'm holding off a couple of years to see if I can get a diesel outboard boat instead.
So, it's increased range for me over normal outboards, including being able to actually refuel in far(ther) flung places. Also, with diesel, I can carry a couple of turtlepac deck tanks for extra diesel - something I certainly wouldn't with petrol.
One would of like to have the voice over the same as some of the Actual Footage because he says it's to rough to go any faster then the next shot is he's idling in the Marina then going past the White Clifs!
It was too foggy not too rough.
What D J said: It wasn't that it was too rough, it was too dangerous to go all out due to the fog.
Would love to se a comparison on a boat where you need to switch from outboard to inboards to get diesel. E.g. the beneteau 32gt. Would be cool to have a outboard diesel so you could keep the storage space. Where I live not many marinas have petrol.
I can’t see it catching on in the leisure market the price difference against fuel savings doesn’t add up when doing lowish hours . If the reliability and durability matches regular diesels I can see it being a hit with commercial operators but for leisure use unless there is some huge increase in performance then £20k premium for a pair over mercs doesn’t make sense . The only reason I think you wouldn pay the extra is for the range but then not many people with this style of boat will cruise more than 100 miles in a day .
Yes and no. People will spend an extra £20k on a boat just to get nicer embroidered curtains.
considering there's no where to get petrol the 20k makes perfect sense.
I've made full post on potential fuel savings, you might be interested in looking at it.
@@darthkek1953 where can I find that thanks
@@mrdiavel4807 you can't direct link on youtube but if you reload the entire video and scroll through the comments you should be able to find it.
We have 2 at work for about 8 months they stay broken down electric issues and lower units issues one had 20 hrs
Thank you from all of us!
£45k per unit...the Mercury 300v8 is £28k per unit...huge price, noise and weight difference. Can't see the value proposition here in the diesels, I honestly can't 🤔
800 rpm idle is high ?
Would like to know the gear ratio/rpm/prop pitch
Also single engine operation .. with all that torque, a single engine should push pretty good
All that matters unless you can’t buy petrol easily is how much the price premium is vs the fuel savings. 45,000 pounds each sounds a lot
Im sure as time goes on and there is more competition, it won't be as expensive. In many boats, though, the diesel engine option is significantly more expensive.
Does it have closed loop cooling with coolant? Or is it a expensive over priced disprin like all the others? 🤔
Is this the same Cox that used to make model aircraft engines
Besides fuel economy, what are the benefits of the diesel engines that are more costly initially? Are the diesel engines likely to outlast the petrol burning higher revving engines from Mercury and other manufacturers? The diesel engines are quite a bit heavier and I’m guessing would put more stress on the hull at the transom.
My 1983 Diesel Mercedes station wagon runs on a few oil changes for the last 40 years and has never needed an overhaul. OM617 5 cylinder turbocharged diesel is listed as the most reliable engine ever built.
Oxe Marine has been doing it for long
Yep, we tested theirs 2 years ago: th-cam.com/video/ek3rP0EiV_k/w-d-xo.html
Oh shit, he has his boat shoes on, he means business.
To properly sell overpriced yachts, one must dress like a playboy in a straw hat.
I could never buy an axopar until i heard about these diesels
Do torque numbers really matter on an outboard? There not a lot of rotating mass to turn, and the size, pitch, number of blades of the propeller have as much of a ( if not more) a determination of what boat does
yes it dose
How about an acceleration test?
I suspect the massive tourk will way surpass the 4stroke.
What about scheduled maintenance?
This is why I'm sticking with 2stroks.
A) both are 4 stroke.
B) 2 stroke outboards are nothing but maintenance intensive shit boxes that are bad for the environment. Just because you have the brain if an ant and can’t work out how to look after a 4 stroke is not a sign of a bad engine. It’s a sign of your incompetence. I’m glad they are being banned more and more.
@@bh8671 I have a brain and experience and unlike you I'm not an asshole. If you don't like something insulting someone who does will not help your cause.
Two stroke engines are FAR more reliable than four strokes. And yes I know they burn oil and that is not the best for the lakes. At least we have stopped dumping raw sewage into them.
Phone Backup I've used a lot of outboards over the years. I've scrapped plenty of four strokes, but I've never scrapped a two stroke. I still look for used two stokes to buy today. During my searches I see lots of four strokes less than ten years old being broken for spares.
They made joystick 🕹 controls for the dual outboards ?
The hydraulic system is from Optimus... They have the optimus 360 joystick. They were used by Yamaha and Evinrude before they had their own, and are available for most outboards... So I guess if money isn't a problem no reason you couldn't have a joystick.
Does it use DEF?
Marine engines have looser emissions regulations so i would say no
Boote Polch👍🏽
The volume is very low jack most of the time you came across as mumbled. Lovely set of outboards though!
Why did the graph show 2850 rpm at 30 kn for a 61 LPH and jack saying 3500 rpm at ~80 lph for the same speed? The graph said he should be doing 41 kn at that speed?
At around 9:50 he mentions going against the tide. I thought the same as you, but tide and wind conditions may account for discrepancy
@@Nasss92 The issue is that he ends the video stating that the top speed was 39 one directiom 42 the other hinting at a 3 kn not 10 kn tide. Followed by the statement that the diesels are slower than the gas why again goes against the graphs that showed the diesels being faster than the gas. Or am i missing something?
@@axelwallenberg6167 We are confused :-)
I can only hazard a guess to be a factor of conditions (i don't know if there is an equal inverse relationship between drag and speed in this case) or possibly any changes to prop selection? It is a test boat after all, but also fair to address his claims look a little off
On the axopar website it shows that the twin Mercury 300 was pushing the boat 50 knots how come on your test run you only claim 43 knots top speed?
The website lies? Don't believe everything you read.
@@zzz7zzz9 nope, in fact it's can go more slightly more than 50 knot
Did I hear 45,000 pounds per? What is the payback on that in diesel savings? That’s like twice the cost of gas seems like a lot.
The sea is calm, what's risky???
I dont think they are far enough in front in terms of performance and fuel saving to justify the price and weight.
If they are tender engines, it saves the need to carry gas on board, you just use the same fuel as the ship uses.
@@Ron_the_Skeptic Thats a fair point.
Twin turbos....
Gonna be an expensive refit once those, inevitably, go awry...
They do fit the Axopar, I must say. And diesel does make some sense, I guess.
Hybrid designs with gasoline motor or pure hydrogen ones seem to be the way ahead, though. The fanatics WILL come for marine diesels as well.
Excellent review, as per.
They are already coming for marine diesel, all sorts of new superyacht regulations etc.
Hydrogen fuel cells, a lovely idea but thoroughly impractical due to the lack of refueling infrastructure.
@@lukewalker3905 Almost the exact same situation when the combustion engine was created and everyone said there wasn't the infrastructure... Just build it.
TUrbodiesels have been in cars, trucks, lorries, busses, and mining equipment for decades. It is good technology that actually works.
Remember, this is not a high-revving petrol engine, needing a turbo to spin three times the speed it will in a diesel.
Do these things have an SCR/CAT/EGR and require DEF like the road diesels? What about service intervals/cost? Shame there's no joystick. The gauges seem like they need a software update with letters/logo all smashed up. Hope they're NMEA2000 compliant to work with other systems. I wouldn't want to be the first customer of these units due to a lack of parity with the competition regardless of range. Getting stranded because no one knows how to work on these is a total deal killer.
No
Diesels. Lots of torque... but also lots of weight. And full disclosure, I drive an (American) Ford 3/4 ton P/U with a turbo charged V-8. Fuel burn is good though. 56 liters combined, per hour (~15 US gallons). Our 150 horse (Suzuki 150 4 cylinder) will burn 5 gph at that speed.
150 hp on a 37 foot boat?
Even while heavier the time to plane is greatly reduced as the peak torque is very early in the power band
Better count fuel stops on a long journey.A difference of 100 Nautical miles of range extra on the same boat speed is quite a difference. A third of the range extra on the same tankvolume.
huge convenience! can make one or more fewer stops while having way more flexibility

I'm waiting for the diesel inboard to be invented
Your wait is over
UK prices are ALWAYS grossly inflated. In poor vis with no radar and the door closed lol.
Rpms?
The weight is bonkers 🤨
The engines cost about £10,000 more per unit than a comparable petrol engine outboards so what ever the savings in fuel consumption the real world shows that up front cost of the engines drown out fuel savings.
I think this will also depend how long you intent to keep the outboards how any hours a year use n one hopes also they will cost quite a bit less in maintenance n repairs over the years n the fact they will always be worth more when its time to sell them, but in the short run yes petrols all the way
Not just fuel but servicing too, diesels should run several times over the length a petrol needs a full rebuild. But yes, I think you need to be looking at commercial-level mileage to quickly get a return on investment.
But, also, you know, BOATING. Have you seen the price of upgrades and and options? Ten grand usually struggle to buy you slightly nicer LED lights and a rod rack.
@@darthkek1953 Boating is now for the rich at least well off people I gave up boating when petrol went to 80p a litre but I do remember many of my mates from school they almost all well their eldest brothers/fathers who had any money would get a 10 to 12 foot traditional wooden boat n a little seagull on the back petrol was couple of shillings a gallon them seagulls where very easy to repair but in tidal waters anything less than a 10 HP engine it wont do, last time I went to a bot show (Earls Court) they had Humphrey Boggart on the African queen his steam boat Boggart actually looked pretty life like, anything "Marine" the price goes over the roof now days its silly money

I am totally out of touch with boating never was with anything bigger than 20 foot anyway, two things would worry me If I had money n age on my side for a boat this size, I would be worried of almost a ton in weight for the two engines hanging on the transom in choppy weather also the difference in fuel consumption reliability as oppose to a bigger lower revving inboard diesel, a mate years ago bought the mouldings n build a 39 footer If I remember right Aqua star n his choice was between a Volvo Penta high revving engine or a Caterpillar max speed 1800 revs it was a semi displacement hull, engine/gearbox was just over £20000 that was in the 80s would an engine like that not be cheaper to run n maintain in the long run? am sure today's prices would be in a very different bracket of course but the combine cost of these two monster outboards great as they are would not be more cost effective throughout the life of a boat? for me also the added safety factor just wondering great video thanks for uploading

I just feel boating is getting more and more unaffordable. 45k each? That's way off my radar, the same way a ferrari is. Lucky for me I really enjoy my small boat, because I'm stuck with it.

Why are outboard motors with no multispeed transmission, no suspension system, no computerized braking system, no drivetrain, no wheels/tires/alignment/CV axels priced more than a nice lake house on an acre of waterfront property?

@@David-qs5ii Yep, I know... I actually looked it up when he touched top speed at 70 something.

@@arotom I suppose if you can afford a boat like this ... fuel consumption and cost isn't much of a factor, although I wonder how much fuel they carry onboard.
You need to test the Mercury V12 600HP engine next. Just one engine will do that boat. Two diesels would costs you $US105K. One V12 600HP Mercury is $US 70K Next you could put one (1) of the new Cat 32B Triple turbo diesels with 2,433 HP :)
You want twins on that boat. Both for the redundancy and added maneuverability during docking.
At some point just have a stern thruster and bow thruster- go to a single -
@@lukewalker3905 Bowthruster suff and available.
A single is way better than twins, until it breaks. Then twins are way better than a single.
@@lukewalker3905 the bowthruster is 3'500 EUR on the Axopar 37. On top redundanca on a drand new outboard engine is questionable, as most likely issues you will have are connected to the fuel resp the fuel line, and on a single tank boat your gain of safety is marginal ! Statistics also speak for single.
On top 2 engines = double the maintanance costs.
So single makes a lot of sense ;-)
Brand new equipment is nice to consider but transferring the engines out of the boat and connect them to the tanks with flexible tubes is asking for oil spills.
Today all is nice, what will the condition of the tubes be in a few years of flexing, temperature excursion and solar degradation?
A petrol spill in a harbour sees the fule evaporate within short time, a diesel spill is an environmental disaster much bigger than the advantage given by reduced fuel use.
Did I hear this right? This engine costs $45,000 each?
Buying a new outboard boat is much easier after half a bottle of Tequila!

Is diesel not petrol?
Try this: Put a cup of petrol in a dish. Light it with a match. The fumes are explosive! Now, put a cup of #2 diesel oil in a dish. Try lighting it with a match. It doesn't evaporate so it won't light. We have to fine spray it at very high pressure directly into a very high compression cylinder at 22:1 compression to force it to explode in the very hot compressed air.
If petrol leaks, a spark makes an impressive bomb. If diesel leaks, you'll only need a mop.

This is America and we don’t know kilogram any metric measurements so if you’re going to cater to the US do it in horsepower do it in feet so we can understand what you’re selling us thank you
Double the cost of a Yanmar 300HP inboard with stern drive, so guess what I am ordering?
yanmar putbàrdß are dusélß too
From what I've read on the charts, the diesels are better on every number
yes théy are
Diesel is dead too many exhaust cleaning hardware pieces than gasoline adds more weight overall and if nothing else more maintenance
The marine sectors is far less regulated compared to on road diesels.
Petrol outboards still not necessitate cats yet so diesel needing scr, ad blue and egr and cats is a long way off.
So we can rule that bit off as to why these engines weigh so much anyway... haha
@@lewisanth4986 yes but diesel if it becomes attractive the regulations would become more strict doesn't matter what part of the world they are manufactured especially in the u.s. or Canada and in North America diesel is phased out in a lot of sectors and its easy to see why no glow plugs no grid heaters no plumes of black smoke when its cold no injection pump to replace
@@stevemino142 there is a chance tho, diesel tech has come along way if I may say so.
Only time will tell if they will be a success in the marine sector.
@@lewisanth4986 very true I know from a roadside standpoint as gasoline powered vehicles like the 8.8 litre psi V8 gasoline in buses and mass transit vehicles there cleaner now than any diesel present or past
"Too Risky" over 20 knots?? Would not buy the Axo
Wow, Rolling coal in A boat...
water down the diesel smoke exhaust and your Golden with the EPA....or else !!
