Our Legacy on the Water
Founded on Passion
Erwin Marine Sales was founded by Kayo Erwin in 1978, driven by a genuine passion for boating and a commitment to sharing that passion with others. What began in Chattanooga, Tennessee, has grown into one of the region’s premier boat dealerships, proudly serving boaters across Southeast Tennessee and Huntsville, Alabama.

For almost five decades, Erwin Marine Sales has been dedicated to creating a welcoming, family-oriented boating community while delivering a complete, hassle-free boating experience. Our goal has always been to provide customers with everything they need in one convenient place, from helping first-time buyers find the perfect boat to supporting lifelong boaters with expert service and ongoing care.
Carried Forward by Family
Today, Erwin Marine Sales proudly remains a multi-generational family business, with Kayo Erwin’s grandson, Barrett Chambers, helping carry forward the legacy his grandfather first envisioned. Having grown up in the business, Barrett now works alongside Kayo to lead Erwin Marine Sales with the same values that have guided the company since the beginning — faith, passion, integrity, and a commitment to personalized customer service.

How often should I have my boat serviced?
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.
