MK3-UT MARK-3® (USA) w/ Metal Jerry Can

MK3-UT

  • WATERAX acquired the intellectual property and the rights to manufacture the durable 185cc engine from ROTAX. Always the benchmark in terms of performance, reliability and durability, the MARK-3® benefited from a series of improvements to its key components namely a Nikasil coated cylinder, an impregnated crankcase, and a maintenance-free pump end. The new Nikasil Coated Cylinder is the most significant upgrade on the MARK-3® in years. In addition, WATERAX has adjusted its recommended fuel mix ratio to 50:1 synthetic. Please note that the change to the synthetic 50:1 fuel mix ratio is also valid for older MARK-3® equipped with cast iron sleeve cylinders.

    The improved MARK-3® successfully passed the USDA Forest Service 100 hours endurance test in San Dimas on 08/04/15 and has been requalified under QPL Number 274-001.

    MARK-3® meets or exceeds USDA Forest Service SPECIFICATION 5100-274E.
