Commercial

They also choose us for the supply and installation of major peripherals such as winches and hydraulic anchor winches.

Whether you’re plying the Pacific Island and coastal trade routes, hauling nets or trolling lures in unforgiving seas, 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.

Recreational

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.
