Years on Johnson 18hp, 5 1/2hp, 3hp, and a Ted Williams 15hp?

[boatsalotjay]

Hi Guys, <br /><br /> Just bought 4 motors, one is a 18hp M# FD-11, S# 1585856. 5 1/2hp M# CD-17, S# 2064208. 3hp M# JW17S, S# B67381. Also a Ted Williams 15hp, looks to be around a 70s vintage. Are there numbers somewhere on these to ID them, I also have a 7.5hp Ted Williams that I haven't been able to find #s on. Could someone please tell me where to find the the years, oil ratios, etc... on all of these? I bought them all for $325, also got a nice pressure tank and hose, did I get took? I didn't think so. The 18hp is in awesome condition, and the others are in find shape too. Thanks!

What in the world were you thinking??? <br /><br />FD-11: 1957<br />CD-17: 1960<br />JW-17: 1961<br /><br />All the Johnson's are 24:1 engines. Lots of info can be found on them at:<br />The Old OMC Site <br />The 18hp takes Champion J4C plugs, while the 3 and 5.5hp take Champion J6C plugs. Gaps are all .030". Lower unit oil is OMC/BRP 'HiVis', or alternative brands of 90 weight outboard gearcase oil for all three.<br /><br />The Sears Ted Williams 7.5hp could have been made anytime in the '60s or '70s, so the fuel/oil ratio varies for it depending on which specific year. Here's some guides:<br /> Sears 571 Prefix<br /> Sears 574 Prefix <br /> Sears 217 Prefix <br /><br />Also, some of those engines are air-cooled rather than water cooled, so they take Chainsaw/Weedwacker two-stroke oil rather than TC-W3.<br /><br />EDIT: I belive all 'Ted Williams' outboards were Eska built (217 Prefix). They used air-cooled Techumseh powerheads for their outboards.

Well, lemme see. . .<br /><br />FD-11 is a 1957 18hp.<br />CD-17 is a 1960 5.5hp.<br />JW-17 is a 1961 3hp.<br /><br />All use a 24:1 fuel mix, J4C spark plugs gapped at .030" and a point gap of .020"<br /><br />Sorry, can't help you with the Sears engines.<br /><br />Good luck.

Thanks Guys, thats a big help. Paul, did I make a bad choice or were you just kidding me? Oh, and I found out that the 15hp Ted Williams was a 1973.

In the last year, I've become the proud owner of an FD-11 also. It is the second outboard that I've worked on, and I must say, it's a pleasure to own. I love working on it, it's a lot of fun. I think you made a great choice, at least on that one.<br /><br />My only problem with the 18 is that it's not a 30

Sorry, Paul. You out-typed me. <br /><br />My Johnson book calls for J4Cs for the little hummers. I guess they do well with either. I would use the J4Cs for high speed running, J6Cs for trolling and low speed operation.
