I put it on port just because there’s 2 holes already drilled and tapped on that side but none on the starboard. Not sure I trust myself drilling into the jackplate and tapping the holes but I guess if that’s what’s gotta happen then so be it.
As far as angles I’d I place a level on the transducer it’s completely level. That’s what I’m looking for right? And yes it’s a g3n mega si transducer.
