Remove the rivets/bolts/screws from the old transom board. The transom support will move enough out of the way to remove/replace the board. I've replaced 3.

If you do remove the support look for the extra large pan headed bolts. Can't remember where I found the ones I used on the transom. I had to buy a box of 50.

Try it like Cane said. Helped neighbor replace one couple of years ago and that's how we did it. Where we had to cut out rivets in transom just replaced with stainless bolts, washers and lock nuts.

Thanks. Yep, I have decided to go back with stainless pan head bolts. However, on this little boat (10') it is impossible to get the wood behind the support without removing it unfortunately. Thank you

If your going through bottom of hull, find you some stainless elevator bolts. They have a larger, thin, flat head. You should find a hand full at a garage door place or if one close a shop that repairs big truck trailers will have some. Clean the spot where head will hit bottom of boat. Clean it real good and when ready to install put a coat of JB weld on it just before you tighten it up.

The wood on the ones I rebuilt were thick plywood. I had to cut it to get them out. I traced on new 1/2" plywood, cut. 2 layers of paint, slid in 1 layer of plywood in at a time. Added a 3rd layer of plywood across top, above support for motor mount. Replaced the original aluminum mount plate. The 3 layers of plywood was 1/8 to 3/16" thinner than the original boards.

Charlie, I needed some elevator bolts 4- 3/8X 3 1/2" when rebuilding the floor of my camper. I couldn't find them that long anywhere. Ended up welding all thread to the ones I bought.
Stickers, here's a chart for average cost for the elevator bolts. https://www.boltdepot.com/Elevator_b...-8_1_4-20.aspx
