Mercury’s Heavy Duty Series of inflatable boats is designed for daily pleasure or professional use. They are built strong enough to take larger engines, with the largest model able to take up to a 50 hp FourStroke. Special reinforced fabrics and a durable aluminum floor will handle you and all of your gear, year after year. Amazing is simply an understatement. Whether you choose to stay on board or roll off the pliable sides with your dive tank on, the Heavy Duty Series is ready for your next outing.
