One my 32 I can reach the back of the thru hull by reaching into the plenum from the side of the boat. I had to remove dry and reseal mine as tiara never bothered to seal them off on the inside of the hull. They don't have a hose hooked up because there basically just a drain for the plenum box but any water that gets into the box will sit at the back side off the fitting and leach right into the coring. Tiara really dropped the ball on these plenum drains.

Awesome, thank you!  We are hauling out this weekend, so I'll give it a shot from the outside.  That sounds way easier than the alternative.  How did you dry it out?  I plan to scrape out some core around the fitting and fill with epoxy before replacing the drain as well.
