Lockwood-Ash #A880

Listed below are some of the easiest to identify "tells", a feature indicative of a particular year(s) motor. Remember, you need more than one "tell" to date a motor since it might be a made-up motor. If you have a motor where both the cylinder head tells and the lower unit tells exist and agree, then you can feel confident you have a complete model...(not counting the gas tank and other odds and ends).

• access to the gearbox is gained through the end of where the prop shaft enters. On later models the access is through the top of gearbox.
  
  
• The exhaust manifold is not water cooled. It's quite easy to tell because there is a water outlet pipe on top of the cylinder. On later models the pipe is not there as the water goes directly into the exhaust manifold. Additionally, the narrow end, nearest the spark plug, of the exhaust manifold is squared off on the early model and pointy on the later models.
  
  
• The tiller on the early models is somewhat similar to the early model Evinrudes. The early model Lockwood-Ash tiller was cast from aluminum and is a more pleasing design however. There is a flat bar that the tiller handle slips over and is fastened to. On later models the tiller has a wooden handle with a round shaft which is screwed in place.

The above information also applies to Lockwood-Ash made Motorgos.
