Hi,<br /><br />I recently inherited from my dad a Johnson 4hp outboard. The Model number is J4RCEC and the serial number is B 7938979. From what I can gather from reading posts and following links is J=Johnson, 4=4hp RC Rope start in the Model number and B in the serial number is Belgium, which is all correct. I still can't figure out the year. <br /><br />Also, is a 50:1 oil mix ratio correct? I kinda remeber him saying this a long time ago. Using next weekend and would appreciate any help.<br /><br />Thanks,
