The 25HP Sea Horse motors are the precursor to the better-known K&O Sea Dart motors. The white version of this motor is slightly more common than the red version. They feature a very similar “boxy” design which is a noticeable profile in the later Sea Dart motors. The Sea Horse motor has a more simplified design with no faceplate, chrome rear plate and side cowl trim. The on/off switch is located on the front of the motor and the terminals have “pin” terminals rather than the K&O “fork” terminals seen in later years. Although this motor carries the “Sea Horse” name, they are not Johnson branded motors. The Sea Horse 25HP motor is a rare and seldom known early K&O generic. These motors were made in the early 1950’s and are only available in two colors, white and red. The construction of this motor is delicate and often seen dented or warped.

Notable Traits:

• Height: 3.5 inches

• One of the smaller K&O motors available
