This boat is variously powered by a 1953 Evinrude Big Twin and a 1958 Evinrude Fastwin, depending upon which motor is more cooperative.  We are presently working on a 1954 Johnson 25hp electric-start which we hope, at the very least, will ease the strain on my aging rotator cuff.Since acquiring the boat over 10 years ago, we have replaced the transom, several frames, the keel, and dashboard.
