Unfortunately, that's one of the conundrums of boat building. The bolts of choice are Stainless Steel because of their strength and corrosion resistance. But, they are dissimilar to the Aluminum that the outboard engine is made of. That's where the use of sacrificial zincs comes in. Just remember that the less dissimilar metal there is, the less potential there is for galvanic corrosion.

If God didn't have a purpose for us we wouldn't be here, so
Live simply, Love generously, Care deeply, Speak kindly.
(Leave the rest to God) 
Silence, in the face of evil, is itself evil. Not to speak is to speak, not to act is to act. God will not hold us guiltless.
