I would like to tap a barbed fitting into the aluminum gearcase of my
outboard motor. I cannot find stainless barbed fittings and I assume
brass and aluminum touching under salt water is a no- no. If I tap
the aluminum to take a stainless 1/4" bushing and then thread in a
1/8" barbed brass fitting will there still be corrosion problems.
There are several zinc anodes on the motor and aluminum hull.


Umm - first question - why?
