§ 183.75 Applicability.

Manufacturers of vessels to which this subpart applies must use test weights that are not less than the recommended weights set forth in Table 183.75. Table 183.75 details the weight (in pounds) of gasoline outboard engines and related equipment for various rated power (horsepower) ranges.

Notes:

¹ Dry weight is the manufacturer's published weight for the shortest midsection increased by 10 percent to account for longer midsections and additional required hardware usually not included in published weights. This weight is intended to represent the heaviest model in each power category. For boats designed with a transom height of 20 inches or less, the weight in Column 2 may be reduced by 10 percent. Recalculate Columns 3, 4, and 9 as appropriate.

² For diesel outboards, replace the value in Column 2 with the manufacturer's published dry weight + 10 percent.

³ Running weight is the dry weight plus fluids (including 2-stroke oil) and the heaviest recommended propeller. Calculated as 5 percent of dry weight.

⁴ Swamped weight is 85 percent of running weight.

⁵ Rigging and controls include engine related hardware required to complete the installation (e.g., controls, cables, hydraulic hoses, steering pumps and cylinders). Calculated as 5 percent of dry weight.

⁶ If the boat is equipped with a permanent fuel system and is not intended to use a portable tank, the portable fuel tank weight may be omitted.
