Default Ideas for repairing binnacle mount

On our little Henry O the binnacle/control has pulled loose from the gunwhale. This is an '89 model boat and appears to have happened over the years as there are two sets of holes. This may also have

been the result of a re-power in 2004. Recently I epoxied the holes and re-drilled them and re- mounted it, but it didn't last long.
Rather than drilling more holes in search of "fresh" wood, I'm thinking of epoxying something similar to starboard to the gunwhale and mounting the control to that.

If I go this route, what are some good materials to consider, and how would you "glue" them? Otherwise, what other options?

Is it possible to through bolt it? Large fender washers, lock washers, and nuts would make that pretty secure if you can reach the back side.

This... but if that is not possible I suggest the following:

Buy a cutting board at Walmart.

I know that a sheet of King Starboard HDPE is superior but for this application that would be overkill.

Cut a rectangular piece of the cutting board a little bigger than the size of the binnacle.

Pre drill screw holes in the corners of the piece.

Mount binnacle to the piece either with through bolts or sheet metal screws.

Pre drill pilot holes in boat where piece mounting screws will go.

Screw piece to boat.

Enjoy!

Could try rivnuts, if the fiberglass on the backside is sufficiently strong.

Nope, can't get to the back. Only option there would be toggles and maybe some kind of nutsert.

Is it possible to cut an inspection hatch below the binnacle , say 4" or enough to get a hand up there to thread on the washers and nuts ? Then of course cover the new hole wit an inspection cover.

Repair the holes

Use West System reinforced epoxy and glass cloth not quick set stuff
you can get small bit of thin cloth at Home Depot for few bucks
tape off the holes, scrape and clean out the bedding from the holes
Mix the epoxy 1:1, wrap strip of cloth around a tooth pick and make a plug. Saturate the plug, ( it will get smaller as you wet it, so make it a bit oversize) leave the toothpick in the repair
sand it flat next day and drill out the toothpick or drill new holes 3/4 inch from old holes

reset the control ( it's a side mount not binnacle ). Use 4200 or Loctite marine adhesive sealant when you re install

That is not a binnacle mount control, it is a side mount control. The most sensible thing to do is to build a mounting plate that corrects for the angle, then screw that to the hull and attach the control to it.

Glad to se the two above terminology corrections , side mount controls , not binnacle

I repaired same situation on an old side mount
control, I used 1/2 in. C DX plywood coated/ sealed with two coats epoxy resin. Went far enough fore and aft for solid backing , sheet metal SS screws into bulkhead, mounted controls to board.

Thanks for all the suggestions, and corrections. 😉

Side mount control. Lol. I knew that, but it had escaped me.

You may be able to get to the backside to through-bolt, if you are willing to install an inspection hatch just below the control.
