About

Safer Boating Through Better Maintenance

That’s more than a tagline — it’s how we work. At Proactive Marine, we believe in servicing your boat the right way: with clarity, consistency, and care.

We’re a team of marine systems engineers based in West Auckland, specialising in inboard diesel engines and drivelines for launches and yachts. From routine servicing to full rebuilds and repowers, we keep things methodical and predictable which is exactly why we created the BETA Service Cycle.

Here's how we do it:

My partner, hired James from Proactive Marine to look into some issues he had with his diesel engine on his Davidson 28. He said James was was an excellent communicator, very professional and James was more than happy to share his expertise with my partner. He said he would highly recommend Proactive Marine and would continue to use him in the future for servicing. 10/10

James was super helpful assisting us with assessing an engine on a yacht we were planning to buy. He is an excellent communicator and a pleasure to deal with. Would not hesitate to recommend his services. Will certainly use again.

We engaged Proactive Marine to repair our damaged propeller and check complete drive system after hitting a log on our 12m launch. James managed the whole job including sourcing a new prop and having specialist Coy check the transmission. His technical skill in repairing and aligning the drive train has resulted in enhanced performance - we reckon about 150 to 200 rpm for the same cruising speed of 16knots. Very professional and efficient service.

James is very good at what he is doing, works very tidily and sticks to his quotes. And he has helped me source parts much cheaper than I could find them. Plus he is a pleasant easygoing guy. I'm very happy to endorse Proactive Marine.

We recently purchased a 1950s wooden launch, and James has been a huge asset in terms of both assessing the state of the engine prior to purchase, and completing some initial maintenance. James has been great at setting out different options for us to consider, including options to repair parts in some cases rather than replacing them. James communicates well and is great to deal with. No hesitation in recommending James to others.
