This final rule updates the table of outboard engine weights used in calculating safe loading capacities and required amounts of flotation material. The engine weight table was last updated in 1984, and the Coast Guard Authorization Act of 2015 requires that the Coast Guard update the table to reflect a specific standard. This final rule is effective June 1, 2018.
