We got the dorads in finally. We lots one in a storm during the passage from Cobo to Mazatlán.
Mostly cleaned up and ready for dorad and base. For now we are not going to put any sealant around the dorad base, just screw it in, well after drilling the holes :) We are deciding how to handle the open close feature of the dorads.
We have a 1978 Islander Freeport and it has hoses that run to the bilge and then the engine room.
