At Key West Marine Services, we specialize in diesel marine repair, diesel engine service, and mobile marine maintenance throughout the Florida Keys. We are lifelong mechanics, engine builders, problem solvers, and boating professionals committed to keeping diesel-powered vessels operating safely, efficiently, and reliably.
As a fully mobile marine repair company, we bring professional diesel engine service and marine mechanical expertise directly to your marina, private dock, yacht club, boat lift, or waterfront property. Whether you own a center console, sportfishing boat, yacht, charter vessel, or commercial vessel, our goal is simple: provide dependable diesel marine service that keeps you on the water with confidence.
Built on a Lifetime of Diesel and Mechanical Experience
Owner Kameron Haynes has spent nearly his entire life working on engines. Originally from Holly Pond, Alabama, Kameron built his first engine at just 12 years old, beginning a lifelong passion for mechanics, engine performance, and precision repair.
He graduated from Holly Pond High School with an Advanced Technical Diploma and vocational training in Machine Tool Technology, building a strong foundation in machining, engine components, diagnostics, and mechanical systems.
Over the years, Kameron owned and operated a trucking company, built custom hot rods, rebuilt high-performance engines, and developed extensive experience diagnosing difficult mechanical problems. That background translates naturally into the demanding world of marine diesel engines, where accurate diagnostics, preventative maintenance, and mechanical experience can make the difference between dependable performance and costly downtime.
Today, Kameron brings that same craftsmanship and attention to detail to every diesel marine repair, from routine diesel engine maintenance to complete diesel engine rebuilds.

Diesel Experience You Can Trust
Marine diesel engines are built for durability, but they still require knowledgeable service and regular maintenance. Small issues involving fuel delivery, cooling, electronics, transmissions, or lubrication can quickly turn into expensive engine repairs when left unaddressed.
Our team focuses on accurately identifying the source of a problem before recommending repairs. We service diesel-powered recreational boats, sportfishing vessels, luxury yachts, charter boats, and commercial vessels with the same attention to detail.
Our reputation is built on:
- Diesel engine expertise
- Accurate diagnostics
- Honest repair recommendations
- Reliable workmanship
- Clear communication
- Quality parts
- Fair pricing
- Dependable mobile service
- Long-term customer relationships
Our goal is not simply to replace parts. We work to understand what caused the problem and provide a dependable solution.
Licensed and Insured 100-Ton Master Captain
Key West Marine Services also brings the real-world boating experience of a licensed and insured 100-Ton Master Captain.
That experience provides a valuable perspective when diagnosing diesel engine performance, mechanical issues, and vessel systems. Understanding how a boat behaves underway allows us to evaluate problems from both a technician's perspective and an experienced operator's perspective.
From engine performance and reliability to maneuverability and onboard systems, that practical knowledge helps us deliver solutions designed for how your vessel actually performs on the water.
Our Commitment to Florida Keys Boaters
At Key West Marine Services, we believe diesel marine service should be built on experience, honesty, and quality workmanship.
We do not believe in unnecessary repairs or replacing parts without first identifying the true source of the issue. Whether we are servicing a diesel fuel system, troubleshooting an overheating engine, diagnosing an electrical problem, or rebuilding a diesel engine, our goal is to do the job correctly and help prevent future problems
