Figur ed since i had to pull the engine for leaking transom seal, i'd go ahead and clean up the motor mounts. They wouldn't budge with the engine in the boat so i remove the two lag bolts to the hull. Not a drop of rust or corrosion on those. they looked brand new!
The single bolt to the engine bracket, however, is destroyed...both sides. #3 in the pic is what i'm talking about, and want to replace. In fact, I'm probably gonna go ahead and just replace the nuts and washers too. #5 looks in good shape and the engine was super smooth prior to removal
So...i've read a number of thoughts, reviews, etc from all walks of 'marine' sites. Problem is, after two posts they all dive into a SS vs mild steel vs bronze vs you suc vs no you suc in-fighting. I get shear, dead load, etc. etc. characteristics but to be honest, I'm thinking a SS bolt and nuts should suffice right? I mean, i get the moisture blah blah, but the reality is they won't be submerged.
The existing ones i soaked for almost two weeks with PB and other chemical baths. Tried LOTS of heat. in the end, both top nuts (called locking nuts right?) rounded out so i had to cut the bolt
