I'm in the process of getting a manual for my new (used)engine but need some info ASAP. The main questions are the following:<br /><br />1) What is the proper Champion spark plug code? One store is asking which ignition system and I don't even have a clue how to tell. The plugs in it are RL82C but this is not either on their list!<br /><br />2) Is the best manual the Seloc or Clymer?<br /><br />3) Is the year in the model number? My number ends in 91C and I'm thinking that means 1991. Just trying to make sure. I know the boat is 91 and believe boat and motor purchase new together.<br /><br />4) Does anyone have some good links for more information on this motor? So far I have found www.yandina.com, www.outboardparts.com and www.maxrules.com. <br /><br />Thanks in advance.
