Awesome customer service.

Approx three months ago I made my first purchase from Newport buying a trolling motor & battery for my fishing kayak. I couldn’t be anymore pleased with the products. In fact, I purchased a second motor & battery for my son’s kayak which is a different model so I had questions. The Newport employee that I spoke with took the time to explain the differences in the products and what would work best with my kayak. Scott I
