Dual wheels provide a stable ride for your VOModular6 or VOModular8 rigid boat versus single wheel designs. Most of the weight rides on the wheels and the foot rests are used to pull the boat to/from the launching site. The VOM8 Kit folds up under the seat when the boat is in the water. Axle and connector tubing are aircraft alloy aluminum with a hammertone silver powder coated finish. Kit includes an extra clevis pin to secure the oar blades together during transport. Transport Kits for older Venture Outdoors inflatable pontoon boat models may still be available. Call the factory at 435-734-1405.
