We offer seasonal maintenance packages designed to prepare your boat for the unique demands of spring commissioning and fall winterization. These services include battery inspections, bilge checks, and complete safety system evaluations. Routine maintenance isn’t just about preventing issues, it’s about optimizing your boat’s performance. A well-maintained vessel offers smoother rides, increased fuel efficiency, and fewer surprises during peak boating months. At Erwin Marine Sales, we keep detailed records of your service history, enabling us to provide proactive maintenance that extends the lifespan of your boat.
When something goes wrong, you need fast, accurate solutions. Our advanced diagnostic equipment allows us to quickly pinpoint mechanical, electrical, or structural issues with precision. Whether it’s an overheating engine, a faulty fuel system, or an unexpected leak, we diagnose and fix the problem efficiently to get you back on the water. Our repair capabilities range from minor cosmetic fixes to complex engine rebuilds. We can service sterndrives, inboards, and outboards, as well as troubleshoot everything from navigation systems to onboard HVAC units. If your boat is still under manufacturer warranty, we can handle warranty-approved repairs using authorized OEM parts, preserving your coverage and ensuring peace of mind.
Whether you’re looking to enhance comfort, safety, or performance, we offer expert installations for your boat. Add a new GPS chartplotter, marine audio system, LED lighting, underwater lights, or depth finders, our team ensures seamless integration and optimal function.
We believe in using only the highest quality parts to maintain the performance and safety of your boat.

Whether you need a replacement water pump, new propeller, navigation lights, or upgraded throttle cables, we’ve got the parts and the expertise to install them right. Looking for boating essentials? We also stock a curated selection of marine cleaners, safety equipment, fenders, and covers.
OEM parts ensure that every replacement matches factory specs for durability and performance. Combined with our technical knowledge, this commitment means fewer follow-ups, smoother rides, and more confidence every time you launch.
Most boats should be serviced annually to keep them running smoothly and help prevent unexpected issues on the water. Typical maintenance may include oil and filter changes, water pump impeller service, battery testing or replacement, and general system inspections. Most manufacturers recommend servicing your boat once per season or after a certain number of engine hours. At Erwin Marine Sales, we generally recommend service every 50 hours or at least once a season. Always refer to your owner’s manual for manufacturer guidelines, or contact our service department, and we’ll be happy to help you determine the best maintenance schedule for your boat.
