Help needed to identify this motor

[jindanjor]

Hi, I'm in the UK and recently bought a house that bizaarely came with about ten outboard motors included. I've identified some of the complete ones but still have several part-complete ones and boxes of parts that I need to match them up with. Can anyone help ID the one in the photo? I have checked all over but can't find a brand or serial. I have two separate covers for Mercury & Johnson engines, so think it may be one of those.

seriel # will usually be on a plate stamped & mounted on the left outside clamp bracket!! If missing =look @ the top rear=upper engine (powerhead_ area for a roung looking plug/cap- it covers some water port sometimes -should be a number stamped in there. In the pix i can barely see maybe? that id plate on the left side clamp bracket! need that model #.

That's an OMC product (Johnson or evinrude). As a guess- 2 cylinder, mid 70s to late 80s, 25-50 hp. Need some better photos to narrow it down, but as mentioned, there may be an ID disc embedded in the top of the block- it should have the "OMC" brand stamped into it, as well as the model and serial number.
