You should have the 2 strainers on the engines, 1 for the genset and another for the AC units. You also may have a thruhull for a raw water washdown that may or may not have a strainer... It's been a minute since I've owned/been on a 39, but if I remember correctly, it was aft of the engines on the starboard side. I believe the Bose system was plugged into 110 behind the unit. You need to unscrew the unit itself to access. I don't recall if this was GFCI.

Again... I'm going off memory, so others may correct me if I misspoke.
