Does anyone have or know where to find some throttle/shift controls for a 1968 Johnson 55 hp outboard? My set has the start control handle broken off and it is difficult to move. Also, does anyone know what wires go to what on the ignition. It shows the following letters on the back; b, m, m, s, a. I am assuming that b=battery and a= accessory and s= start, but the two M's are confusing and they do not have continuity in any position the key is in or between them selves. Also not sure what wires go to each. Thanks in advance<br />Dtucker
