I don't have the s/n with me, but I've identified this engine as a 1982
Johnson 235. It was remanufactured by a professional company sometime in the more recent past. This question doesn't really matter, because the engine works fine, but I'm curious. I've been lead to believe this is a cross flow engine because OMC didn't build loopers in the V-6's until the mid-80s? I've kind of oriented myself to looper vs. cross flow and see an obvious difference is the surface of the piston: cross flow have a dome sort of shape, while loopers are essentially flat. When I look through my spark plug holes, the pistons appear dead flat. Just curious. |

Just curious. piston crown has little to do with it. port structure is more important. cross flow engines typically have 2 opposing ports intake/exhaust. loop charged engines will have multiple intake ports and an exhaust port. |
