Morning Brandon.....<br /><br />The FD-17c is a 18hp from 1963.<br /><br />The 125183C is a 125hp from 1971.<br /><br />HMMMMMM.....my explorer seems to have taken a time out...can't find the info you may need. If one of the other guys don't post, I'll throw some more info in when I get to the shop. The books never take a time out..... <br /><br />EDIT: Little info:<br />18hp....plugs are J4C gapped at .030<br /> Fuel mix is 50:1<br />Standard ignition....points/condensers..Points gapped at .020.<br /> Gear lube..hi-vis.<br />Water cooled....has an impeller and t-stat.<br /><br /><br />125hp...Electric shift.<br />Plugs are a L76V gapped at .030 but engine will idle better with a .040 gap.<br />Fuel mix is 50:1<br />Ignition system is 12V driven distributor. Amplifier is on the side of the engine. Points under flywheel.<br />Gear lube is a premium C lube or a lube which is made for an electric shift.

OBJ<br />Not to doubt your wisdom, but weren't 1963 model motors 24:1 and the switch to 50:1 started in 1964? Seems to be a little confusion as to when the changeover occurred and maybe you can straighten me out.<br />thanks

Re: info on motors needed

You are possibly right angus. I can't remember what year the change over took place....it was in this general time frame. Maybe Dhadley or one of the other guys can set us straight. <br /><br />Thanks for bringing that up....

"If your motor was alive when JFK was, mix it 24:1. If your motor doesn't remember that terrible day, mix it 50:1"<br /><br />This was a sign on the counter of a shop I used to frequent as a kid in the late 60's. I guess old Willard, the owner, was tired of answering the question and show his Irish.

If you're looking for confirmation angus63, I'll provide it. A good example is my '64 28hp factory service manual, which states 1 pint for 6 gallons (50:1) for the '64 outboards, but has a note to keep running '63 engines at 1 quart for 6 gallons (24:1) after break-in.

Thank you Paul, I guess the sign was correct...<br /><br />Old sea horse<br />Be safe and mix it 24:1
