I would hop over to scream and fly and ask those guys. Tons of knowledge just like this site but all outboard guys.

There are a couple of NPT plugs in the plate (exhaust adaptor) that the Powerhead bolts to, starboard side.
Tap into that and you’re golden.

There is also a 1/8, maybe 1/4 NPT port that is plugged from factory on top of the block, between the heads just behind the fly wheel that I like to use so you know the pressure at the top of the block.
