I was recently given a Johnson 5 hp motor. <br /><br />The model # is LD-12A<br /> serial#J2756478<br /><br />What mixture do I need to use? 50/1, 25/1, and is that 1 pint oil to 6 gallons of gasoline for 50/1?<br /><br />The prop on the motor has 8 x 7-1/2" on it? It also has 3 blades. I can't find a new one with 3 propellers. Any suggestions. Anything will help this novice boater. THX

That motor is a 1967. You can get a manual (a generic one is fine) that will answer many questions and help you keep it running.<br /><br />As for propellers, the only one that the iBoats Prop Finder lists for that motor is the 8 inch 3 blade model. Michigan Match makes those but you may have a hard time finding them in stock.

Here on this site (at bottom of page) are links to Clymer's and Seloc generic manuals. I personally like Clymer's, but that's just an opinion. <br /><br />Good luck!

Your correct mixture is 50:1. Buy any good 2-cycle oil (like Pennzoil) and the mixture formulas are right on the container.<br /><br />Good luck!
