Who We Are
Tri-State Mobile Marine is a professional, on-site boat maintenance and service company dedicated to keeping your boat reliable, safe, and ready for the water. We proudly serve boat owners across Ohio, Kentucky, and Indiana by bringing expert marine service directly to you—at your home, storage facility, or marina.
What We Do
We specialize in outboard engine service, trailer maintenance, fiberglass repair, and professional boat detailing. Instead of hauling your boat to a shop and waiting weeks for service, we come to you with the tools, experience, and attention to detail your boat deserves. From routine maintenance and diagnostics to cosmetic repairs and full detailing packages, our goal is simple: save you time, reduce hassle, and keep you on the water with confidence.
At Tri-State Mobile Marine, we believe quality workmanship, honest pricing, and clear communication should be standard—not extras.
