Who Are Octomarine?

"Exceptional Assistance & Service..."

Exceptional assistance and service… could not have been better.

Cpt. Bob Corcoran . M/Y Samar

"Great Service & Attitude..."

I have alway used Octo Marine from the start of my time in the Med. I really like the service, the attitude and the crew at Octo Marine. Nothing is a problem you go to any lengths to help us out weekend or night. When I change my water makers I’m going to change to your own brand so I can have the back up. I would not use another water maker service when in and around the Med.

First class service!!!

Chief Engineer Juan . M/Y Willow

"Happy Engineers!"

I have worked with Octo water softeners with many vessels I have worked on. I had the pleasure of recommending this product to a fellow engineer who jumped at the product. The unit has arrived here in Australia and we are installing it in the boat now. Happy engineers.
