Marine Diesel Traders

Marine Diesel Traders, formed in 1988 by Sunny Newitt and Lyle White, has grown to become one of the largest used marine engine traders throughout Australia.

View from the MDT workshop
Located on the Brisbane River, Marine Diesel Traders have extensive experience (need advice?) and stock on floor to help you make any important decisions concerning the size and brand of propulsion unit to suit your boat.

If the marine engine, transmission or parts that you’re looking for are in our catalogue, fillin the online ‘Buying?’ form, or feel free to come into our pleasant showroom facility -- the staff at Marine Diesel Traders are always happy to run up an engine of your choice on the floor. If the engine you want isn’t in our catalogue, don't hesitate to contact us - we can probably find it for you! All used engines are sold with a three month warranty.

On the other hand, you can sell or trade in an existing engine or transmission on one of the many makes and models available from 50 to 3000hp. Just let us know what you have, and we might be able to help you out!

Marine Diesel Traders also offer resources for owners of marine engines in the handy Info Toolkit section of this web site. Contact us if you have additional information or links which may be of interest to fellow boat owners.

Beta Marine

Beta Marine make propulsion diesels from 10 to 180 bhp and gensets from 3.5 to 41 kVA. Their website is simple and easy to use, but only provides very basic technical data.

Beta Marine web site


Caterpillar have a huge corporate site but the design and organisation are very professional and user-friendly. On-site specs are of necessity minimal (they have 175 different marine propulsion diesels listed!) but they have a massive spec sheet library of downloadable PDFs. Propulsion engines range from 63 to 7270 hp, marine auxiliaries from 75 to 2550 hp and gen sets from 50 to 590 kW.

Cummins marine diesels range from 76 to 2000 hp and their gensets from 5 to 95 kW. The data sheets are either in the site or downloadable. The navigation menus are hard to read but otherwise it’s a straightforward site.

Cummins web site

John Deere

“In 1962, an archaeological team from the University of Illinois unearthed the exact location of the blacksmith shop where John Deere developed the first successful steel plow in 1837.” There’s plenty more like this on this big corporate site but it’s so well organised you can quickly zero in on the hard data on their 75 - 450 hp marine propulsion/auxiliary diesels. Detailed specs available as PDF downloads.

John Deere web site

Detroit Diesel

Detroit Diesel are, like MTU, a subsidiary of DaimlerChrysler. Their marine diesels range from 375 to 3650 hp (auxiliaries 400 to 550 hp). There is no technical detail on the site (some of which is difficult or impossible to read due to its design) but excellent spec sheets are available as PDF files.

Detroit Diesel web site


Deutz have been making diesels since 1898. Their marine propulsion engines range from 14 to 5600 hp and their gensets from 5 to 550 kVA. It’s a clean-looking, well organised site with basic specs and detailed data sheets downloadable as PDFs.

Deutz web site


Kirloskar manufacture diesel engines rated from 19 to 270 hp and gensets from 2100 to 6300 kVA. Not the easiest site to use (better with Netscape Navigator than Internet Explorer) but the technical information is reasonably detailed.

Kirloskar web site

Komatsu Diesel

Komatsu Diesel makes marine engines and gensets but apart from the genset output range (100 to 800 kW) you won’t find much information here. At time of writing the marine engine page was “under construction”. (Your kids might like Kikki’s Workshop which is populated by jolly elves and bulldozers.)

Komatsu Diesel web site


Lugger’s website is one of the fastest; it looks good and is simple to use. The home page cuts to the chase with pull-down menus for their marine diesels (70 - 900 hp) and gensets (5 - 520 kW) They provide downloadable PDF spec sheets and AutoCAD drawings.

Lugger web site


Formerly the Imperial Torpedo Works, MaK have a range of marine diesels and gensets from 1,400 to 22,000 hp. Their website is clean and simple but contains an impressive amount of data and photographs of the engines, their components and manufacture. You can download their service magazine as a PDF.

MaK web site


Maschinenfabrik Augsburg-Nürnberg (who made the first diesel engine) have a huge range. The big ones (610 to 93,360 hp) are produced by the subsidary MAN B&W. Unfortunately the German website doesn’t work on all platforms or browsers so you may be better off going to the MAN B&W British or Danish sites which have detailed specs and downloadable installation drawings. For the the 200 to 1300 hp range go to the MAN Nutzfahrzeuge site which has detailed specs as downloadable PDFs.

Mitsubishi Heavy Industries

Mitsubishi Heavy Industries make marine diesels from 325 to 5150 hp. The website provides a moderate amount of technical data on their 6, 8, 12 and 16 cylinder models.

Mitsubishi Heavy Industries web site


MTU (who used to make Zeppelin engines and luxury cars) produce diesels from 50 to 12,240 hp suitable for marine propulsion and gensets. Their site is well designed but there is only basic technical detail provided.

MTU web site

Perkins Sabre

Perkins Sabre don’t have a very professional-looking website, but the amount and organisation of the technical information is excellent, as are the photographs. Engines range from 67 to 300 hp, auxiliaries from 40 to 161 kWm.

Perkins Sabre web site


Rolls-Royce’s website is huge and not very user-friendly. Their marine diesel propulsion engines (Allen, Bergen, Crossley Pielstick) range from big (1,600 hp) to very, very big (20,000 hp). They also manufacture an impressive range of deck machinery, steering and propulsion gear, and less conventional engines. If you’re looking for a modified aero engine for your PT boat or a nuclear reactor for your submarine, start here. Detailed specs on application.

Rolls-Royce web site


Scania’s marine propulsion and auxiliary engines output from 200 to 800 hp and their industrial generators range from 150 to 375 kW. The site is well set out and provides detailed spec sheets as downloadable PDF files.

Scania web site

Sisu Diesel

Sisu Diesel’s marine propulsion (85 - 280 hp), generator (25 - 1800 kW) and industrial (60 - 350 hp) diesel engines are described with fairly basic technical data on this simple, easy-to-use website. Interesting to note this Finnish company’s version of the assembly line: one person assembles the whole engine from the beginning to the end; when the engine is ready, the worker attaches his/her own nameplate onto the engine.

Sisu Diesel web site web site

Volvo Penta

Volvo Penta’s product range includes marine diesel engines from 10 to 1877 hp, marine gensets from 90 to 1430 kWe and industrial engines up to 564 hp, as well as gasoline and water jet engines. The site is well designed and easy to navigate and provides detailed spec sheets as downloadable PDF files. You can also download AutoCAD files of some of the engine drawings.

Yanmar Diesel Engine Co.

Yanmar Diesel Engine Co. make marine propulsion diesels (9 - 4500 hp), marine auxiliary diesels (200 - 4700 hp) and Industrial engines (3.4 - 112 hp). The Japanese site has no English language version and the US site is “under construction”, but the European site has basic technical information on their extensive product range (and some very spiritual copywriting).
