What Our Customers Say
“Bought our boat through Wally and the experience was outstanding from start to finish. He walked us through every option, never pushed, and made sure we got exactly what we needed. Delivery day was seamless.”
“The parts department is second to none. Karen went above and beyond tracking down a discontinued part for my engine. Had it in two days when other dealers said it would take weeks. That kind of service keeps me coming back.”
“Family-owned and it shows — they actually care. Bought a Highfield with a Yamaha and the whole process was personal and straightforward. Shop local, support places like this, and you won't regret it.”
“Best boat store in the world. The tackle shop alone is worth the trip — incredible selection and the staff actually knows what they're talking about. We drive 45 minutes past other shops just to come here.”
“Tom and the crew don't just sell you a boat and disappear. They follow through after the sale — helped me with winterization, spring commissioning, and even a warranty issue. Real people who stand behind what they sell.”
“Been a customer for over 40 years, since my father brought me in as a kid. Three generations of Monahans and they've never let us down. Wouldn't go anywhere else.”
Family Business on the Water
Monahan’s Marine has been putting boaters on the water from the same location on Washington Street in Weymouth since 1961. Boats, engines, service, tackle — everything under one roof with the personal touch only a family business delivers.
