Outboard Motor Weights

This table is taken from The Code of Federal Regulations and is many years old. ABYC has a much more up to date table that accounts for more divisions of horsepower and for weights of four stroke engines.

WARNING! Should you decide to use the ABYC table, double check your calculations, to make sure that it meets or exceed the requirements of this table.
