I think I may have found my leak

So my aluminum engine bracket has been filling with water. I think I found the problem. Not sure how I missed it before. It felt like there was some obstruction in there but it might have gone through. Water pressure is pretty amazing. According to some online calculators you can move 3 gallons/hour through a 1/16" hole with a .44psi differential. (.44psi for a foot of seawater).

Now comes the big question, do I reseal all the through bolts since I have the lids off. They were an absolute bear to get off and I just used lifecaulk on there. If I'd use 4200 or more I might never get them off!

Life caulk or any other Marine caulk. IMO, of course.

I use Sikaflex 291 for everything.

It is cheap and can be released with a heatgun.
