Boats up to 50' and 1600 horsepower require heavy-duty equipment. The new Pro Series Grand Slam 400 Outrigger Base is the beast you need! It's increased girth and weight is designed to handle the additional pressure from torque and whip the longer outrigger poles generate. As the "big brother" to the popular GS-280, the new GS-400 will power through a day of offshore excitement and be ready for tomorrow. If you can take it, so can they!
