Hijacking is rude, Signa. Start your own thread.

There is supposed to be a plate on the transom mount bracket, but is is sometimes missing. If it is not there, then look for a quarter sized freeze plug on the powerhead that has some numbers stamped on it. Usually the model number appears there also.
