Mariner Mechanical
Veteran-Owned Marine
Expertise You Can Trust
Across Western Australia
At Mariner Mechanical Services, we provide reliable, high-quality marine mechanical solutions for boat owners throughout WA.
As a veteran-owned business, we approach every job with discipline, precision, and integrity, whether you need routine servicing or urgent repairs.
As authorised Volvo Penta certified mechanics and Yanmar engine specialists in Western Australia, we use advanced technology and hands-on experience to keep your vessel performing at its best.
Our Story
Mariner Mechanical Services began in July 2025 when Jaryn and Naomi took over the business. They wanted to rebuild trust, improve service, and update how things were done.
The company was previously known as Mariner Diesel Services. Since taking over, the new owners have taken the business to the next level — introducing modern technology such as detailed photo reports for servicing and pre-purchase inspections, along with more accurate record-keeping to meet the expectations of today’s boat owners.
Since the beginning, our goal has been to restore confidence, set higher standards, and provide reliable, professional marine mechanical services throughout Western Australia.
Our Journey So Far:
- July 2025: Business purchased and rebranded to Mariner Mechanical Services.
- Right away, we worked to resolve past customer concerns by improving our communication, being more transparent, and raising our service quality.
- We upgraded our operations by introducing modern diagnostic tools and streamlining our service processes.
- We also built stronger partnerships by becoming an official dealer for Volvo Penta and Yanmar.
- Our client base has continued to grow, now including both recreational and commercial marine customers.
Today, Mariner Mechanical Services has built a reputation as a reliable option for boat servicing and repairs. Our experience, accountability, and focus on continuous improvement set us apart.
