Decided, as DaleH pointed out, to install the washers to prevent scraping/damage to bracket from hex heads digging into the alum bracket. Although it doesn’t call for washers on Merc install procedures for this year / model motor, I’ll feel better once installed. It’s my OCD!!

Since the motor bracket side does not allow for standard size washers, I noticed on my friends 75hp on his new toon, that the washers were about the same size as the hex head…. exactly what is needed.

So I stopped by my local Merc dealer in town and asked the service guys about this issue of washers on bracket side …. They said washers were not needed…. However, they had the smaller OD washers from previous installs/repowers and sold me 4 for 5 bucks!! Mercury wants like $5-8 a piece!!

Now….. what’s the safest way to install these…..I’m assuming one bolt at a time?

Also, will be using Boat Life Calk… it’s supposed to be safe on aluminum.
