We are really very pleased with the 200. We knew we would be slightly underpowered but required a diesel for range, fuel availability and safety. Obviously we are waiting on the 300 with interest but the 200 is a pleasure to use and a reassuring engine to have behind us!
The OXE not only reduces operational expenditure on our vessels, but also increases the capabilities of outboard vessels as well as the overall safety of the vessel.

Although the diesel engines [OXE Diesel] are more expensive than the petrol engine when purchased, this is covered after approx. 650 hours of operation due to lower consumption and lower fuel prices
Apart from the high torque of ΟΧΕ 300 at low rpm which is strongly felt after 2500 rpm, what impressed us the most was its extremely low noise levels that it really makes it ideal for long working hours without tiring its operator.
What did we think about the new OXE diesel outboards! In a nutshell we were impressed. They alter the expectation of what a diesel should look, sound, and perform like. If the cowling didn’t have the word diesel on the side, a novice boat owner might not even think to question what type of fuel to put in the tank.
The EU is determined to deliver on its commitments to reduce greenhouse gas emissions, and we are working with Member States on their plans to become carbon-neutral by 2050. Cimco’s outboard engine project drastically reduces emissions, while enabling the coast guard and rescue police who use the heavy-duty engines to continue carrying out their work at sea.
The more we think about the decision to go for a diesel, especially for areas away from the South Coast, the more certain we are that we’ve made the right choice. The OXE is a thoughtful design married with a convenient and safer fuel.
Some of our commercial boats operates all around the country, and Europe and it is becoming harder to get hold of petrol… Having a diesel outboard engine will work in any small commercial fishing port or harbor that we operate on.
It is well known in the boating industry that the popularity of outboard motors continues to trend upward. I/Os are dead in the water. Inboards now seem relegated to midsize and larger motoryachts. Twin outboards are so passé. Triples and quads are de rigueur. Besides adding another motor to the highly reinforced transom of, say, a 40‘ (12.2m) center-console fishing machine, are there any other options? Well, yes, sort of. There is an emerging market for diesel outboard engines (outboard motors was always a poor choice of words).
Diesel outboards are changing the game ! The fact that diesel isn’t as flammable as gasoline is a huge advantage. Mega yacht tenders rely on the mother-ship to supply the smaller tenders and have only one source of fuel is a huge help.
The block [OXE Diesel power head] is mounted horizontally, … rather than vertically like an outboard. Another thing it has in common with diesel inboards is a sealed fresh water cooling system with a separate heat exchanger that keeps the more corrosive salt water well away from the engine’s internals.
It also means there’s a separate raw water pump and strainer mounted high up on the front of the engine rather than buried inside the leg, so that you can clear any blockage or replace the impeller from on board without having to lift the boat.
These features may not sound as sexy as variable valve timing or a big capacity V8 outboard but for people who rely on their engines day after day, things like this matter.
Proteum, has been demonstrating to commercial operators the low Total Cost of Ownership (TCO) of the OXE Diesel outboard in comparison to petrol equivalents. Based on in service data, an operating scenario over 5 years shows OXE’s TCO to be, on average, £100,000 less than a petrol equivalent.
The diesel runs very well, its quieter than I thought it would be. The pickup is very good. The economy is a big thing for me …that was at least half the fuel I would burn on my 250HP Yamaha, so very interesting!
At the heart of the Oxe diesel outboard is a marinized 4-cylinder GM turbodiesel automotive powerplant. As with any marine diesel engine, it provides the advantage of a safe, inexpensive fuel source, with the added advantage of allowing single-fuel requirements for companies running a diesel-powered fleet. High torque provides performance that’s equivalent to a slightly higher-horsepower gas-powered outboard.
Because the engine is fresh-water cooled with a built-in heat exchanger, the Oxe outboard allows easy addition of a bus heater connection at the bypass circuit. And because the transmission is an electro-hydraulic multi-plate clutch design, it not only provides smooth shifting and crash-stop protection, but also provides a built-in low speed trolling mode that eliminates the need for (and costs associated with) a separate trolling motor.
In use, the Oxe diesel outboards distinguish themselves by being mostly indistinguishable from the well-proven and well-loved gas-powered outboards most mariners are familiar with. Because they have a fairly deep exhaust note, at idle the Oxe outboards can actually seem some- what quieter than a gas outboard. At higher revs and wider throttle settings, they have a distinctive muffled growl that’s been compared to the Dark Knight-era Batmobile
The highest compliment I can give this new diesel outboard is that it doesn’t seem any different from a 200hp petrol unit, except that there appears to be more torque at low and mid speed ranges, which could make it particularly suitable for use on a heavier cruising craft.
Our in service data shows OXE’s higher purchase price is recoverable after 700-1000 hours and sooner for operators unable to reclaim VAT on petrol when compared to an equivalent petrol outboard
I got on board a 21-foot Highfield 660 RIB with a 150-hp OXE diesel outboard on its transom, the first oil-burning outboard to meet EPA Tier 3 emissions standards in the U.S. OXE’s parent company, the Sweden-based Cimco Marine claims it’s 55 percent more fuel efficient than a 150-hp gas outboard—an eye-opening statement.
The OXE Diesel are quiet and powerful. For the pro user operating from ships they are perfect not having to bring petrol on board the ship. Moderately heavy, typical turbo diesel characteristics, fully electronic controls, expensive but fuel efficient. Strong, but a petrol engine is faster, especially on lighter hulls.
The challenge has always been getting the right engine and the right packaging. A diesel engine with similar performance to a petrol version tends to be a lot more bulky and a lot harder to marinise. The clever bit with the OXE Diesel outboard has been getting the right size engine into an outboard style of delivery that can deliver the performance you need.
Cimco Marine AB is working on a new 250-300hp OXE diesel outboard based on BMW’s excellent 3.0-litre six-cylinder engine. It seems the diesel outboard revolution is just getting started
The demand for a reliable diesel alternative (outboards) to inboard diesel engines is extremely high as many customers buying gas outboards as an alternative would like longer engine life, more load capacity and greater fuel economy. The customer base for diesel outboards spans the entire commercial market from patrol craft, crew boats, water taxis, work boats, governmental and military vessels, fishing boats, etc.
It is very important in this new market segment to have OXE receive the first EPA Tier III commercial certification for diesel outboards as production of these new motors begins.
Commercial operators have been wanting a high performance diesel outboard for a very long time to benefit from diesel’s lower maintenance and longer service life. OXE has solved this need, proved its reliability and is ready to go!
I suspect the engines (Diesel outboards) can have a big impact with outfits like the Coast Guard, in commercial applications or for recreational boaters who run the heck out of their boats. Weekend warriors will never make up the cost.
I ran some numbers and came away impressed. The 2.0L turbo is definitely torquey. I had Chris Ponnwitz, marketing specialist for OXE distributor Mack Boring firewall the throttles and the RIB was on plane in less than five seconds on its way to 32 knots in 15. It’s also stingy on fuel: At an optimum cruise of 3250 rpm, the boat ran at 24 knots and burned a minuscule 5.9 gph, good for a 294-mile range. Don’t expect a clamorous powerplant, either. I measured 73 decibels at the helm and 78 at the transom at idle. (The wind and water obviated a true reading at higher speeds, as the RIB is an open boat.)
After driving my boat with 2 x 200 HP OXE for over 400 hours this year I am very pleased with this innovative product! My main reason for selecting OXE was the lower consumption and long service intervals, but I am equally impressed by the low dB and how smooth the gearbox is, especially since I use joystick to maneuver a lot. Thumbs UP!
During the demonstration two of us in the back seat where having a conversation at library speaking levels. I was stunned. This is an interesting engine.

Having a diesel engine like this reduces the fire risk compared to petrol engines and it reduces the different type of fuel the ship has to carry. I think navies will be very interested in something like this.
NAVY OUTLOOK MAGAZINE
We are very impressed by the low noise emitted by the OXE Diesel 200. At idle it emits under 67dB measured at the engines with cowl on and in the cabin of an Aluventure 1100 the noice levels are 67dB at 28 knots and 70dB at 33 knots. The low noise levels allows for long working hours for the users without risking fatigue due to noise.
What is really great about the OXE-Diesel is that you get better fuel economy, about 55% better than standard petrol outboards… We had the engine on the boat for 96hrs, overall I think we have burned average of 2,7 Galons per hour.

The OXE is faultless; the smoothness; power; and thrust of the engines are amazing. We can achieve speeds of 20 knots in a boat that weighs in excess of ten tonnes. The OXE’s excellent fuel economy shows with all three engines running to their maximum we have a fuel burn of 90 liters per hour which is phenomenal.
