Looking for leading brand marine engines for sale? Whether you’re a recreational boatie in Auckland or running a commercial marine business in Fiji, our engineers will minimize your downtime and maximize your safety - no matter which brand of marine engine you're using - and no matter where in the world you are.
Getting the best from your marine diesel engine will save you money and increase efficient work time. Our expert team of engineers will provide you with a comprehensive, technically superior one-stop-service – and be there for you, 24/7.
Commercial operators of coastal traders, commercial fishing boats, passenger ferries and other commercial craft come to us to keep their vessels running efficiently and minimize downtime.
They also choose us for the supply and installation of major peripherals such as winches and hydraulic anchor winches.
Whether you’re hauling nets in heavy seas, plying the Pacific Island and coastal trade routes, or carrying passengers to and fro across the harbour, the safety of your crew and passengers is paramount. So, don’t leave it to chance - make the right choice of marine engine and call us as soon as possible.
At Shaw Diesels, we work with you to ensure a regular servicing and maintenance programme is developed to suit your schedule - and the nature of your business.
When summer approaches and you turn that key for the first time in months, you want that trusty old marine diesel to ‘kick into life’ right away. The last thing you need is for it to ‘die on you’ while you’re out on the water!
In our experience, too many boaties leave servicing and maintenance until their craft won’t start - or worse still, until something breaks down and there’s an emergency situation.
Regular servicing is the simple, safe, cost and time-effective answer – and that’s where pre-planning comes to the fore. A single phone call to Shaw Diesels before you head out on the water might not only prove to be a money-saver, but in an extreme event - a life-saver!
We’ll make sure your craft is dependable and kept in good running order, all with your safety in mind, and that of your family and friends. You can bring your engine to our workshop or call us and we’ll send someone to you.

We stand by our reconditioned engines, which undergo thorough cleaning and repairs.
We pay good money for second-hand marine engines for reconditioning or rebuilding, and then resell them.

We supply and service diesel generators for commercial vessels and larger pleasure craft. Whether it’s your commercial fish freezers or lighting for ferry passengers, or your refrigerators for refreshments, we can help you ensure they’re all kept in working order.

Marine projects Shaw Diesels have undertaken:
The Adventurer II
Shaw Diesels supplied a Gardner 6LXB engine (127HP @ 1500rpm) for The Adventurer II, a replica single-screw, tunnel-hull riverboat for multi-day guided tours on the Whanganui River. The Adventurer II is owned by Jos Ebben, Robert Baldwin and Bob Harris, and was built to brave the 239 rapids and cruise the serene waterways between Whanganui and Taumarunui.
A major servicing of the main engines – two Deutz 620 V6, gensets, and two Deutz 1015 V6 – was undertaken on the MV Tribu at Auckland’s Viaduct Harbour.
Alica Craig - engine rebuild
Director Dave Shaw had many pleasurable but challenging hours rebuilding this Alica Craig engine in his workshop. The engine was built in the 1950s and is a 30hp @ 1200rpm. Just one of a few three cylinder engines left in the world, the engine was destined for reinstallation into a New Zealand-built kauri launch.
Cecil Peak Station
Shaw Diesels rebuilt a Gardner 4L3 and 3 UC gearbox for the famous and remote Cecil Peak Station in Queenstown. The engine is used in a barge that carries supplies across Lake Wakatipu.
We did a major refit for Zenji, the impressive sailing yacht, while the yacht was based at Viaduct Harbour. The work involved taking the two Deutz 616 V12 engines into our workshop for servicing.
Prior to the relaunch of the historic Jane Gifford, Shaw Diesels rebuilt her two Gardner 4LW engines. The Jane Gifford was built in 1908 and is the last of the traditional rigged sailing scows in New Zealand. She originally carried granite to Auckland from mines on the Coromandel.
Our staff serviced two x twin Gardner 6LXB marine propulsion Engines for MV Windana rated at 140HO @ 1700rpm.

Above we have provided a short video demonstration of a Dong I Marine gearbox which is our recommendation for an economical and light weight replacement for the original Gardner gearbox.
