The steering arms have rusted all the way through. Port side is broke and starboard side bends easily.
I have disassembled the port engine. What a PITA!!!  On almost all of the bolts, there seems to be some kind of grease on the threads. Those that had grease are nice and rust free and came out without issue. The others have corrosion from the aluminum (bolts are stainless) that made their removal very tricky. I was able to get the port side disassembled without breaking any bolts. I did have a couple that almost broke as the heads aren't quite flat anymore but with patience and lots of PB they came out. I had to grind off the head of one of the lower rubber mount bolts. The nut came off but the bolt was stuck in the housing (no grease) that hold the bottom of the steering arm shaft.
So is it normal practice to grease up bolts during assembly? If so, I'm a big believer in it after taking this salt-only motor apart. Could this be some kind of marine anti-seize perhaps?

Be careful what grease you use , go to a boat shop and ask what there mechanics use !.
I use lanocoat grease made from the lanolin from sheep's wool on every thing i have ever taken apart and never had a problem.
I also wash down with warm soapy water and spray crc all over everything when its dried off .Be generous with it so it gets to all the places you cant see
Seems when the motors are assembled theres no grease used at all !. Stainless and aluminum + salt always stick together ! best loctight combination Ive come across ever !.
Yamaha , OMC Mercury and all the others have tubes of grease that are for different applications, . Handy to keep in your tool box in the boat !
