Performance benefits

Torque moves boats

OXE300 produces peak torque of 945nm at 2250 RPM, more than any other outboard on the market and approximately
50% more than an equivalent horsepower gasoline outboard. This translates to
massive bollard pulling power, as well as fast hole shot acceleration.

The engine idles at 720RPM with already high torque levels at idle,
making it ideal for station keeping and close quarter manoeuvring. The robust
hydraulic gearbox means that the engine handles multiple forward and reverse
shifting without damaging the gearbox and is very responsive compared to traditional
outboard gearboxes.

OXE outboards can fit up to 17-inch diameter propellers,
larger than most 300HP outboards, opening opportunities to match the correct
propeller to best suit the application and take full advantage of the OXE.

Probably the most fuel efficient 300hp outboard

At wide open throttle, the engine consumes a maximum of
69 litres per hour at 4300RPM, approximately half the consumption vs a gasoline outboard equivalent
and is why we say that it is probably the most fuel efficient 300HP on the market.
Depending on the hull and application type, our customers typically save between
30-40% on fuel consumption on average and therefore significantly extends the
operating range of the vessel.

Smart choice for the enviroment

The OXE300 is approved to run on HVO100, a fossil free diesel which significantly reduces the overall CO2 footprint.

In our own empirical study on the same hull and comparing twin OXE300 vs twin gasoline 300HP, at cruising speed the OXE300 resulted in a 92% reduction in CO2 footprint vs gasoline and 88% reduction in CO2 footprint vs regular diesel.

Running on regular diesel, the OXE300 had a reduction in CO2 footprint of 32% vs gasoline.  

Smart choice for the enviroment

An outboard engine built to last

The OXE300 is warranted for 1500 hours of operation with
different time limits depending on the type of warranty policy. The engines are
serviced at 50 hours and 200 hours followed by 200 hour service intervals, which is
double the time of regular gas outboards allowing for more time in use.

Electrical output

The OXE300’s alternator delivers 180 amps, far higher than
other 300HP on the market. This enables the boat equipment to be powered by the
engines and allows for boat batteries to be charged and often negates the need to
have an onboard genset.

Simon Hill
Western Mariner

"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 somewhat 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".

"It's not often one sees an outboard go viral, but when it does, it's an OXE."

"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."

European Commissioner

"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. OXE Marine'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."

Andrew Reynolds
Trend Diesel

"OXE’s were the obvious workhorses for our operations. With 45% less fuel consumption comparative to gasoline outboards, high engine torque and thrust, remote availability of diesel fuels, engine cabin heater options and higher operation cruise speeds makes OXE a great fit."

Dan Spurr
Professional Boatbuilder Magazine

"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) centre-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)".

"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"
