Synergy Boat Lifts features several unique differences. An all aluminum bolted frame that gives our boat lifts 35% to 40% more structural strength than conventional welded frame boat lifts. There is no more worry about improper welds or welds structurally cracking over time. Additionally, our toggled pulley system was designed to be horizontal (=) to the cable shaft as opposed to standard pulleys systems that cross the cable shaft (+). Our innovative toggle pulley system operates with less stress while decreasing wear and tear on both the cables and the pulleys which translates to a more reliable and safe boat lift that will be there for you time and time again. Also, our service-free top bushings eliminate the messy process of using grease to ensure the cable shaft functions smoothly and properly. Synergy Boatlifts are a more reliable, dependable and worry free boat lift that you can depend on every day, year in and year out. When comparing Synergy Boatlifts feature to feature and dollar for dollar with any other lift on the market we are confident you will choose Synergy Boatlifts. Synergy boat lifts are designed, engineered and manufactured in the United States. We offer full manufacture warranty on all of our products.
