I've been trying to figure out what year my outboard motor is with little success. Its a 5.5 hp evinrude fisherman. I wanted to check the lower unit oil but dont have a manual and dont want to mess it up to be honest. So i was looking for an online PDF manual, with no luck. The serial number on it is 204393. I couldnt find a model number. and i've narrowed it down to 1956-1964. If anyone can help i'd greatly appreciate it. Thanks! Tim
