GENERAL INFORMATION

Serial Number Location

The Outboard serial number is located on the lower starboard side of the engine block. A

serial number is also located on the top side of the swivel bracket.

It is a known fact that weather conditions exert a profound effect on power output of internal

combustion engines. Therefore, established horsepower ratings refer to the power that the

engine will produce at its rated rpm under a specific combination of weather conditions.

Corporations internationally have settled on adoption of I.S.O. (International Standards Or-

ganization) engine test standards, as set forth in I.S.O. 3046 standardizing the computation

of horsepower from data obtained on the dynamometer. All values are corrected to the pow-

er that the engine will produce at sea level, at 30% relative humidity, at a temperature of 77

F (25 C) and a barometric pressure of 29.61 inches of mercury.
