I just acquired an older 5hp Montgomery Ward Sea King and would like to know the year and some tech info available. The moter is made by Clinton Engines according to the nameplate. The numbers are as follows:<br />Model: K5002106A<br />Serial: 710523<br />Type: 60 27405R <br /><br />I'd like to know the plug type needed and gap setting, point settings, and if there is a place to get a service manual. I think it's water cooled bc I see intakes at the bottom of the LU. If that's the case, where will I find the impeller on it? (Please correct me if I'm mistaken) <br /><br />Finally, I did a visual of the lower unit and can't seem to find the drain and vent screws. Looked all over it and didn't find them. Am I missing something?<br /><br />Any help you may have will be greatly appreciated. Thanks, <br /><br />Doc
