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!

[@andrewbeale2585]

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.

[@darthkek1953]

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._

[@deven6518]

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.

[@blobbblob]

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 :)

[@Mr91495osh]

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.

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.

[@darthkek1953]

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.

[@bobuncle8704]

Thanks for doing the math

[@altergreenhorn]

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

[@darthkek1953]

@@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.

[@petercrane2065]

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 .

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.

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.

@@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.

[@polygamous1]

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

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.

A single is way better than twins, until it breaks. Then twins are way better than a single.

[@femo66]

@@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 ;-)

Is diesel not petrol?

[@LarryButler-kp3se]

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. kzbin.info/www/bejne/baTSh6SvfNZnn5Y

Diesel is dead too many exhaust cleaning hardware pieces than gasoline adds more weight overall and if nothing else more maintenance

[@lewisanth4986]

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

[@stevemino142]

@@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
