I'll be dealing with a similar situation pretty soon, hopefully by the end of the year. Gonna take the trim unit from a 90HP midsection and install it on a 70HP engine using that same system.
I'll be following along!
I did find a couple of links which might help a little.
That's what I thought. I strongly urge you to use aluminum for your underdeck reinforcement joiners. The last thing you want is steel rusting under your deck, rotting things out. :)
This is how I did my underdeck aluminum joiners. ☺️
I had a 14' Sea Nymph which had a hole and I patched it with JB Weld from the outside. It never leaked after the repair during the short time that I owned the boat. Not the best way, but it worked.
I have similar through-hull pitting on my Chief too. I sealed it up on the inside with JB MarineWeld and will be adding an aluminum patch (which is already made) on the outside. If I ever get back to work on the thing! 🙃😆
Unfortunately, my wife has to work tomorrow and the boy has school. :confused:
So, I'll just stick around here and hope that the angles and clouds are right so that I can see the launch from the front porch. 🚀
