That’s what I did to make mine. I added quick connects so I could go back and forth from auto to outboard testing. I drilled a 3/8" NC stud to let the air through and threaded that into a male quick connector with a thick rubber washer to seal it to the gear case. Works great, and the 3/8 thread fits OMC, Merc, and Chrysler at least.
