Hello! I can't seem to find a model # on our Johnson 150HP. There is a paper tag on the motor from previous mechanical work done by previous owner. The # on it is 91224 and 185777 and it says CYL AY and 150HP. I don't know if these mean anything or not. Also, the # stamped on the plug above the cylinders on the left rear of the motor is 338632. Could anyone tell me if any of these are the model # or if I can use any of these #'s to obtain the correct manual for the motor? Thank you SO much!!!!
