Neander Dtorque 111 turbo-diesel 50hp outboard

Running off the back of the world’s first turbo-diesel motorcycle created by in 2005, German-based Neander has released a revolutionary turbo-diesel outboard engine with big claims and big backing.

Using a unique dual-crankshaft configuration, the diesel outboard engine has pistons acting on two opposing crankshafts via two connecting rods, resulting in almost vibration-free running, the company claims.

With an aluminium cylinder block, dual crankshafts and common-rail injection, Neander can construct powerful and compact lightweight diesel engines suitable for use as outboards.

The first of Neader's new diesel outboards is the innovative and sharp-looking 50hp Dtorque 111 pictured above,.

Power Equipment, the local Yanmar, Neander, Torqeedo, John Deere and Oxe engine distributors, tells us the new Dtorque 111 diesel outboard is likely to be available in Australia in early 2017.

NEANDER DIESEL OUTBOARD SPOTLIGHT
>> First dual-crankshaft turbo diesel outboard for low vibration
>> Dtorque 111 model creates 50hp @3500-4000rpm
>> Full torque at just 2000-3000pm
>> Common-rail diesel injection
>> Weight of 175kg

FIRST NEANDER PRODUCTION MODEL
Neander's first production engine, the Dtorque 111 is a low-revving 50hp outboard with 804cc capacity. The engine produces 111Nm of torque at 2000-3000rpm and revs out to just 3500-4000rpm.

With maximum torque produced at 2500rpm, the Dtorque 111 has more torque than the best-performing 70hp 16-valve electronic fuel-injected four-stroke petrol outboard on the market today.

Employing Bosch common-rail fuel injection, the engine's diesel consumption is claimed to be 10-12 litres per hour at full throttle compared with 30-40 litres per hour flat-out with a petrol outboard equivalent.

But there is a weight difference. The 50hp Neander Dtorque 111 tips the scales at 175kg compared with, say, the Yamaha F70 at 120kg or Mercury 60 Sea Pro four-stroke at 118kg dry.

FURTHER POTENTIAL
Neander says there is the potential with its new dual-crankshaft technology to create from 12hp to 110hp diesel outboards, using from as small as a 400cc single-cylinder engine up to a 1.4 litre two-cylinder engine. Such engines would produce torque from 25Nm to 220Nm respectively. Generator applications are also mentioned.

Along with claims that its low-cylinder diesel engines also use 35 per cent less fuel than petrol engines, Neander also says they produce low CO2 emissions, while offering that abundant torque for acceleration. And all this with low vibration.

Power take-offs can be fitted to run other on-board equipment, while the inherent safety of diesel as a fuel source isn't to be sniffed at.

The prime applications for the Neander outboard will be in the
commercial marine, offshore, military, fishing, rescue and
charter-sector. The diesel outboard would also perfectly serve tender boat requirements
on large yachts storing diesel fuel only.

YANMAR BACKING
Marking its return to the diesel outboard market, engineering company Yanmar Marine International (YMI) has agreed to exclusive distribution rights with Neander.

From 1985 until 2009, Yanmar manufactured three-cylinder diesel outboards rated at 27hp and 36hp, but ceased when EPA and EU RCD emissions regulations restricted their sales in key markets.

"With the Neander we can offer a highly competitive outboard product with outstanding engineering," said Floris Lettinga, YMI Global Sales Manager.

As part of the distribution agreement, Yanmar has taken an equity stake in Neander Motors.

LOCAL DIESEL OUTBOARD SALES
Luke Foster, GM of Power Equipment, told boatsales.com.au that his Melbourne staff have had training in Europe on the new Dtorque, as well as the unique Oxe diesel outboard engines made by the Cimco Marine in Sweden.

The Oxe is belt-driven 2.0L four-cylinder engine that produces 200hp at 4100pm and uses a hydraulic multifunction clutch for gear ratios from 1.73:1 to 2.17:1. This way, you can slip the clutch for trolling and go straight from forward to reverse without stripping gears.

Both the Neander Dtorque 111 and Oxe are unique diesel outboards in different ways, but they complement Power Equipment’s suite of alternative engines that include the electric Torqeedo motors, as well as its traditional Yanmar and John Deere diesel inboard ranges.

Prices TBA in 2017 for the Neander and Oxe diesel outboards. More soon.
