bc.gold 3,403 #1 Posted February 1, 2020 Any collectors, I recently listed a Johnson twin from the 1930's as freebie my first reply. David: Hi, is this still available? What are the changes so you are coming into winnipeg? Share this post Link to post Share on other sites
Cvans 1,009 #2 Posted February 1, 2020 I own a few 1950's to early sixties outboards. All under 30hp. They are OMC's as parts are still available, simple to work on, and built to last forever. The ignition parts are interchangeable and with a little practice can be quickly serviced. 1 Share this post Link to post Share on other sites

stevebo-(Moderator) 8,330 #4 Posted February 2, 2020 I have about 15 to 20 OMC (johnson and evinrude) outboards. They range from 1929 to 1961. Most are 1956 and 57. Everything that Cvans said ... 1 1 Share this post Link to post Share on other sites
Stepney 2,325 #5 Posted February 2, 2020 I have several, from 1924 to 1951. What model Johnson? I love the 20-30's era open engines. Have Johnson's, a Scott Atwater, a Neptune, one Evinrude 4 cylinder 5 horse, and a Martin. Share this post Link to post Share on other sites

I think my engine is older it has cylinder heads secured with four studs with nuts, the exhaust discharge tube is external. These engines are old enough to have platinum ignition points, and the square condenser/capacitor probably made of silver/mica.

bc.gold 3,403 #7 Posted February 23, 2020 With platinum points no pitting or metal transfer from one contact to another. With the sun shining onto the contact under a magnifying glass the iridium alloyed with the platinum gives off amazing colors. My camera is not good enough for macro images.

It's likely somewhere in there. Yours is a bit newer and more improved than mine. The earliest ones had headless jugs. Share this post Link to post Share on other sites
