I’m installing a Saniflo electric head in a 2000 Beneteau 321. The Saniflo electric head (made in France) is attractive because it fits in the same footprint as the Jabsco manual. My problem is running the 12v. Power from the circuit panel to the head. I’ve tried to run a snake through the port under the galley sink and the conduit behind the stove. If I can get to the area beneath the water heater, I can probably judiciously drill some holes to get to the opening behind the head. Anybody have any advice (other than going back to a manual head)?
