At Uncle J Custom Boats, we build every boat to last — and we proudly stand behind that promise. That’s why every new Uncle J hull comes with a comprehensive warranty for the original owner: full coverage for manufacturing defects during the first five years, and a lifetime warranty with capped repair costs after that. From the strength of the hull to the quality of our welds and workmanship, our commitment is simple, giving you lasting confidence on the water.

The length of the warranty, and what is covered by it, varies based on the product purchased. Mercury warranty coverage is factory-backed. Your dealer works directly with us, so you won’t need to deal with independent providers or insurance companies.
