Hmmmm, just a note here to make me remember. I have 2 sheets of cabinet grade birch ply in 3/4. If I use that and a piece of 1/8 hardwood sheet, I should be able to seal and use it for my transom. What do you think? I read in a thread that Barato2 did a test on it and it looked good. Do i need the 1/8? It seems most just use 2 pieces of 3/4, but some use a filler to get to the full width. I seem to remember there is still some extra room.
Good point Frey. I went out and measured(photo). It looks like 1.5" will work but I'll fill if needed. I still need to finish my shop and carport so I can get it under cover and proceed with the tear down. I'm building the engine mount for the Merc on an automotive motor stand today. I need to build another free standing one for the Johnson I have also. right now it's setting on a HD saw horse I built some years ago.
While I don't have the transom out yet, it seems very sound. I'll replace it anyway just so i don't have to worry about it. Don't want this tower of Power to fall off. ha
Wow, that was a mess. Mine seems very solid everywhere I press a screwdriver to it. It's been in there about 48 years though.
