All,
While I am sure this has been answered elsewhere, I did some searching around and am still not 100% sure to install a new through hull fitting. This is part of the long continuing saga of adding another bilge pump to the SeaDNA.
In brief, I have a through-hull fitting (plastic from Rule) that I plan to install on the port side aft. The current plan is to put it about 10-12" above the water line with the center lined up with a similar through hull that was installed on that side to drain the port lazarette (which I use as a live-well or fishbox). The fitting is designed to allow the attachment of 1-1/8" bilge hose from a RuleMate 1100.
Since it is well above the water line, my first thought was to cut a hole of the appropriate size (just big enough to get the fitting through) and to smear a lot of 5200 in the hole and around the fitting and tighten it in. However, various threads here and elsewhere suggest that I should cut the hole a bit larger (or at least dig the core out to a larger diameter) and back fill with expoy prior to installing the through hull. What would you do? It is well above water. Do I really need to gouge out some core and fill with epoxy? If so, how do I fill the top area of the gouged out region without tipping the boat upside down?
Also, how far away from the other hole should this hole be? I'm a bit concerned about weakening the general area of the hull by putting two 1 1/4" holes too close to each other.
Finally, I also considered just putting in a tee at the current through hull. Two things discouraged this idea
1) When I use the port lazarette as a fish box or live well, it can get quite messy (especially when I bleed the fish in there). Hence I was concerned that draining the fish box would put bits 'o fish in the line to the bilge pump that would impair it's operation, smell bad etc. I thought this could possibly be avoided by bending the drain line to make a trap, but then the trap would smell.
2) I couldn't for the life of me find a 1 1/8" tee - 1" yes, 1 1/4" yes, but no 1 1/8".
