Why should I use Shellharbour Marine Mechanical?

When it comes to something as important your boat or jet ski, you want two things. You want a professional who loves what they do. You want someone working on them that cares about getting the best from your boat as much as you do. 

The owners of Shellharbour Marine Mechanical, Nick and Grant, are right with you. They want your boat in the water where it is meant to be and they will do whatever it takes to help you get there.

A few years ago Nick and Grant met whilst on the job and both recognised they’d found a kindred spirit. They both loved the water and gave a damn when it came to their craft as marine specialists.

When the opportunity arose to work together and provide a place on the South Coast, where customers could get both excellence and customer service, they joined forces under the banner of Shellharbour Marine Mechanical to provide just that.

If you want excellence without the fuss, let Grant and Nick take care of your marine needs.
