About Marine Diesel Solutions

Auckland's Premier Marine Engineering Specialist

Marine Diesel Solutions has earned a reputation as a trusted marine engineering partner. Based at Pine Harbour Marina in Auckland, we provide expert maintenance, repair, and upgrade services for both leisure and commercial vessels throughout the Auckland region.

Our Approach

At Marine Diesel Solutions, we understand that your boat is more than just a vessel - it's your escape, your passion, your livelihood and a significant investment. That's why we bring a customer-first approach to every job, focusing on solutions that deliver long-term reliability and value rather than quick fixes that cost more down the line.

Our owner and lead technician, Alistair Spick, brings over 20 years of hands-on experience across commercial vessels, leisure craft, and premium charter boats. His natural problem- solving abilities and comprehensive knowledge of major marine brands — including Yanmar, Detroit and MTU – ensures your vessel receives the highest standard of care regardless of make or model.
