OXE Diesel Outboards

Hello all,
I am researching the OXE diesel outboard engines and would be interested to know if any members currently use them or have heard comments about any problems or other matters of concern.

In particular I am interested in both the 200hp and 300hp engines.

Thank you in advance.

Dubi.

I am slightly intrigued by these diesel outboards.

Despite the single fuel approach on a military or commercial vessel, I don't really see the advantages. Due to higher than petrol NOx emissions (unless they have AdBlue) they surely have a limited lifespan and/or are become the next to be banned or priced out of use.

Am I missing something? Are they cheaper on tax/duty?

Chris

I suppose if you lived in an area where petrol wasnít easily available & you donít want to go down the inboard engine route, then they may have an attraction. But I suspect itís niche.

I'd have one like a shot.
Apart from having seen 2 separate powerboats explode on Poole fuel barge as a young'un, it's always easier to find diesel on the water than petrol once you leave the Solent.

If you own it you can carry on using it, so any existing ones won't be priced out of use.

Relevant to todays boating - not sure, for the life of me I can't remember the last fireball at Salterns marina ( nor any where else..... ) not only would H&S not be happy but it might make the news....

There are several cruise ships that visit Fort William throughout the summer. There is nowhere for these ships to dock so the anchor out on the loch and shuttle the passengers to shore using Ribs, these ribs have the OXE engines on them, they are surprisingly quiet and they can shift.

OXE diesels are going to save you about 40% of total gallons consumed. Notice that I didnít say 40% of your cost. Youíll need to do the math based on the cost of diesel from regular gasoline.

The cost of the engine is almost 2.5 times that of a standard outboard (Yamaha, Suzuki, Honda, etcÖ). If youíre a leisure boater, then itís not worth it. If you operate commercially; 3-4+ days per week, then itís worth considering as the OXE engine with out last all of the above by at least a 2:1 and possibly even 3:1. The data simply isnít out there yet.

Now - on a more positive note, I have access to a 10m RHIB with an OXE 300 on the back here in Southern California. I need to get some pictures and video and Iíll post some YouTube links in the next week or two and share those here as well.

If anyone wants to learn more about the inner workings from a mechanical standpoint; let me know and Iíll share my two cents.

In closing, they are a solid engine. Just cost prohibitive to the leaker market.

Oh, one last thingÖ they are publicly traded on the stock markets and they have significant potential with government contracts. If those take off, it would be like buying Apple, Amazon, Tesla, etcÖ at a couple dollars per share. Iím not trying to peddle snake oil. Simply sharing my opinion here. Look them up and do your homework. Ask your broker/portfolio manager to research them.

I guess the Cox Powertrain diesel outboards would also be an option.

Which one uses the Landrover V6 diesel as the power head?

The newer OXE outboards have a BMW 3.0 litre diesel so I guess the same as the one in a Land Rover.

The Cox is a 4.4 litre engine which I think was developed from scratch.

I saw them at Seaworks a few years ago when they were still in development. I liked the modular approach. They were, or seemed to be, aimed at the commercial/military market, where carrying petrol is problematic. I think they definitely have a place, but due to the physical size & weight, theyíre more likely to find a place on large commercial craft. It would be interesting to see if they could produce a 150hp unit with similar weight/size to a modern 4s petrol.

Bmw's involvement with landrover ended long ago, the oxe is an inline 6 from bmw the cox 4.4 may be the landrover v8 block but they don't seem to want to admit that.

Iím sure the one I saw at Seaworks had a LR Disco block, but I could be wrong. I had a conversation with the guy on the stand about being able to use stock LR spares & parts.

BMW have started supplying Landrover again, the bigger petrol engines in the Sport and Rangerover.

The oxe is an inline 6 bmw engine the v6 disco engine was a joint venture between Landrover PSA & Ford, nothing to do with BMW. You may have been looking at the Cox v8 which might be the landrover tdv8 block as its also 4.4l but that might just be coincidence.
It's possible Oxe did build some prototype engines around the landrover tdv6 but didnt take that forward, who knows Click image for larger version

Yeh I was referring to the m57 diesel engine BMW fitted to the range rover years ago when BMW owned the marque. More recent discos have used the v6 landrover/PSA/ford engine which was nothing to do with BMW. Some current & future landrovers will be fitted with BMW petrol & diesel engines.
Motor manufacturers interbreed so much nowadays its hard to keep track of whats what. You go under the bonnet of a disco & some parts are badged landrover some fomoco (ford) & others psa (peugeot/citroen), its a 3 way love child
