my old evinrude 3 h motor has the lower cylinder blocked off. bolt and rubber plug are in spark plug hole and under flywheel where points and cond. and coil should be there is nothing. all of these parts are there for top cyl. is this some previous owner bypassing a dead cyl? or wanting to use as a troller? will this even work? have worked on a few engines, and have never seen anything like this. any ideas?

Sounds like a hack job to me. How old?

1952. kinda thought hack job too, but actually looks cleanly done. scratching my head. i want to say someone had a cyl. die for some reason ane decided to use it as a single. im a motorcycle tech, and have seen nothing like this.. if it was running, its not at the moment, i would think this would be really out of balance and it would want to eventually shake itself apart. i just dont get it.

It will run just fine on 1 cylinder.
I don't understand it either. The 3 hp twins will idle down to nothing when they are tuned right....
