Our Mission

Safer boating through better maintenance

Better Communication

We keep you informed so you know exactly what is being done today, needs to be done tomorrow, and should be done in the future.

Better Service

We deliver high-quality workmanship and a customer experience to match. Because an oil change is not enough.

Better Reliability

We create relationships based around reliability. As a result, you can rely on your engine, and you can rely on us.

Be Proactive!

Being Proactive is about identifying issues before they become a problem. Likewise, it is understanding that a marine engine service is more than an oil change and that clear communication is key.

James is a legend. After 3 years of low oil pressure that other marine engine service companies were unable to establish cause James knew where to look and identified the issue within 5 mins. Within 1 hour he acquired the required spare part and had it installed. The issue is now fixed. James knew what to look for and got it fixed in record time. Wow!! Highly recommended! I shall be using Proactive Marine from now on.

I have had an overheating issue with my launch for a number of months. After trying all the possible remedies, it still couldn't be solved. I was recommended Proactive Marine to have a look. I left the boat in his hands while I went overseas and came back to a fully working boat. There was no obvious reason for the overheating and Jim took time to find the problem and fix it. I'm very impressed with is work and he even left the boat clean and replaced all the carpets. I will now use him for all my servicing. Ian Clouston
