I do agree with you on the fact that will the flywheel line up in the 12 different positions that is a good question. If so then yes you could flip the flywheel different degrees along with moving the points cam to a different positions to get spark at different positions on different engines in the correct firing sequence. I would think 12 holes were used to give it the ability to be moved smaller degrees + or -.

PM T2 I do respect your knowledge of outboards. Have you ever seen a condenser that large used on outboards? If so which ones? It would look to me it has the ability to hold a lot of charge more so than just a normal condenser if the 12 bolt holes line up then that maybe why its so large.
