What is the best bolt for my application?
I need to replace the motor mount bolts on my Mercury outboard engine.
The original size of the lower bolts is 1/2"x13x6-1/2", and it takes 2 each.
The original size of the upper bolts is 7/16x14x6-1/2", and it takes 2 each.
They go through solid aluminum bushings and will require nuts in the appropriate sizes and some form of recommended locking medium, either washers or loc-tite.
I need them to be of a strong material and of a material that will not create galvanic corrosion in the aluminum.
Can you help?
Thank you for your time and consideration.
