Having trouble with your boat's 4.3L V6 Mercruiser engine? If it's running rough, stalling, or hard to start, the old 2-barrel Mercarb carburetor might be the issue. This is a direct replacement designed to fit all V6 4.3L engines that originally came with the Mercarb 3310-807764A1 carburetor. It's made from quality materials for durability and features an electric choke for easier cold starts. The foundation bolt pattern is 3/4 x 2 inches. This carburetor mixes air and fuel to provide the right mixture for your engine's operation, from idling to full throttle. Important: Carburetor installation and tuning can be tricky on marine engines; it's highly recommended to have a qualified marine mechanic handle the job to ensure proper performance and safety. Does not come with instructions.
