Reply To: 1957 Big Twin Exhaust Tube and Swivel Mount

[Bob Wight]

Buc,
Here’s what I know based on what I did with my ’56 Johnson 30hp:

– You should be able to swap out the transom brackets so you can keep the original model/serial ID tag. If not, easy enough to swap tags out by driving out the drive screws from the back side of the bracket, then re-install on the correct bracket.

– Never seen solid handles for the transom screws. One of mine was broken. Drilled the pin out and replaced the broken handle with a spare I had and made up a new pin.

– To keep from scratching paint when reassembling the exhaust housing onto the swivel tube, I tape off the “ear” where the rubber motor mount engages into the bracket. Hang the housing onto the front mount, engage one of the side mounts, then use a small screwdriver to lever the other side mount into its bracket hole. I then use some tweezers and an Exacto knife to remove the protective tape. Worked real good on my 56 with no paint scratches.
