"Hi all,

acquired this fine and funky specimen in an online auction for a very affordable price. I haven't picked up the engine yet and the seller doesn't have it on hand to check the serial number (he also knows nothing about the unit except that it has two cylinders and starts when you pull the cord - fair enough).

Can you tell from the photo what approximate vintage this is? Judging by some photos in my Clymer manual, it looks post-1978 as far as I can tell (could be totally wrong though). My intuition of industrial design trends would suggest something like the early '80s. Any ideas or guesses?

Something funny happened. I was saying to myself "that looks like an Evinrude with the bottom cowl missing" then I put my mouse pointer over the picture and it states "Evinrude 4hp with bottom cowl missing". I think you have your answer.

** Edit ** Here's a picture of a similar engine http://www.old-omc.de/e_1973/seite_18_19.jpg"

"Heh, I guess I was a bit unclear in phrasing my post. I know it's an Evinrude - that's why I wrote it in the photo caption when uploading it.

As to the date question, I can now answer it myself: just picked up the unit today and the model code is 4.BR.72S, which I guess would make it a 1972 (!).

Anyway, I'll have to see what I'll be able to do with it - the motor actually looks a lot cleaner in real life than in the pic, but the seller's outboard starting (and/or B.S.) skills may be better than mine - at least I wasn't able to get it going in the trash can. Oh well..

Gas and/or oil seems to be oozing out everywhere so maybe the carb is flooding or something; after cleaning the plugs (very gunky), I get a puff or two of smoke, then nothing again. Mind you, haven't done any proper testing yet (or changed the plus, new gas etc.), so it's too early to throw in the towel. But at least it was cheap enough that if it can't be resurrected, I can always chop it up for parts and get something newer. Looks like a fun project anyway...

BTW, thanks for the link - that's a cool site, bookmarked it for future reference."

Well you are only partly right about the identity. Its a 1972 4 hp OK but that is a Johnson model number! However the cover looks like the top half of the cover that was introduced in 1979!

A '72 model will have coil and breaker ignition a 79 model will have CDI

(The B may signify that it was made in Belgium but i am far from sure about that!)

You'll find exploded diagrams and parts lists here:

Have fun resurrecting it!"

"Hi Vic,

Indeed, you are right, a Johnson number it is. I didn't check which section I was looking at in the OMC list, just assuming it was an Evinrude because that's what I was told. Thanks for spotting that! Just another reminder that we don't always know what we "know".

TY also for the link, it will no doubt come in handy."
