CPK - SPEAKING OF NUMBERS - yOU CANT TELL A MOTOR BY IT'S COVER.

Take the cover off and ther should be a round pressed in button with the model # and serial # on the top of the powerhead. These numbers should match those on a plate on the transom bracket. The model number will tell you exactly what it is - yr shaft lenth hp etc. Post it if you want to know what all the letters and numbers stand for.

Gotta go.
