I have a pair of these 20 gallon tanks that came with the 22' Harvey I'm working on. The vent hoses were routed through holes cut in the transom. I'm not sure if that is kosher...Is there some terminal tackle that should be attached to the hose ends? Should the vents exit through the hull sides or is through the transom ok? Finally got the floor and new transom built and installed but neither has been glassed. Weather as of late has not been my friend.
