“I have owned boats for over 15 years and Mainline Marine Service is hands down the most honest and dependable shop I have ever worked with. They diagnosed a tricky engine issue that two other places could not figure out and had it fixed within a week. Their communication was clear, the pricing was fair and I felt respected throughout the process.”
