"Model JW-13, s/n234610 Johnson Motors Peterborough,ON Patented 1956 (Manufactured 1956?)
Motor in good condition, except it is overheating severly. I have disassembled/cleaned/flushed lower unit, . Any thoughts on further remedy appreciated. Also,I would like to get copies of specs/schematic/shop manual etc. for the whole motor for a full understanding (including other aspects ignition,fuel, gear train etc.)
Will also take on 9.9 Johnson in a few weeks - there is good info on this board when the time comes."
