Aluminum & bolting Q
Posted: Jun 19th, '14, 16:38
I ran across an aluminum tail housing for my 471TI. I'm typically no fan of aluminum anything mixed with salt water, but the 50+lb savings could not be passed up. The Detroit 471TI 325hp marine engine came from Detroit with the aluminum tail housing.. so can't be all too bad.
The question is; The bolting that goes into the housing, I can use stainless. How will this react with the aluminum in the salt environment? It's been my experience that carbon steel tends to use the aluminum as an anode and powders female threads.
I believe the Yanmars are basically aluminum engines (but I know little about them). Any "lessons learned" about bolting on these engines?
Any suggestions on anti-seize? Copper based sounds like a bad idea... what about nickel based? .. Or should I use a Locktite type product on the studs going into the tail housing??
Any metal / corrosion experts out there!!
Thanks Scot
