Hi Bill. The muffler can on my ’21 Koban has thirty five 7/32" holes drilled in it. Widthwise they are on 3/8" centres and just slightly under 3/8" the other way. When it comes time to make the new muffler, I’ll drill them all at 3/8" centres both ways. No one will know.
Art Dekalb has repro transom pads.

You wouldn’t happen to have a spare rudder kicking around would you? 😀
