Sea Sea Marine has been servicing boats for over 20 years, blooming from humble beginnings in Sydney's south. 

Having both grown up on the water, Chris and his father John made the transition from car mechanics to birth Sea Sea Mobile Marine. After completing his second mechanics apprenticeship and plying his trade as a mobile marine mechanic in greater Sydney, Chris settled as Sea Sea Marine in Botany, Sydney in 1995, and has plied his trade there ever since.

Sea Sea Marine completes projects backed by a wealth of knowledge, and a passion for outstanding work. The workshop has seen many of Chris' own boats over the years, from fishing vessels to family leisure-craft. Every single boat that has found itself in the workshop is treated as if it were Chris' own, and the same applies for yours. ​

Sea Sea Marine provides honest, quality mechanical work for all in the boating community, regardless of size or application. Chris' stellar work has led him to complete projects across the country, while also being contracted overseas for emergency projects. Don't become a dollar sign for another mechanic - become part of one of the many success stories that began by visiting Sea Sea Marine.



"Great service and overall knowledge. Highly recommended and I will be using from now on for all my boating needs. Thanks Chris."
