"My outboard died at the slip in Sheepshead Bay on a Saturday morning. SJ Express had a marine tech at my dock within the hour. Diagnosed a fuel pump issue, fixed it on the spot, and I was back on the water by noon. Incredible service."
"Been using SJ Express for winterization and spring commissioning for years. They come right to my slip at World's Fair Marina, handle everything from shrink wrap to engine prep. Saves me the hassle of hauling the boat anywhere."
"Generator went out on my cabin cruiser the night before a trip. Called SJ Express and they had a tech who knew Onan generators inside and out. Fixed it dockside at Chelsea Piers. These guys really know marine systems."
