Thru-hull locations?

[ElBichoMalo]

Can someone identify all of the "factory" thru-hulls? Location, size, material, plumbed to what? Also, what have you all done with them...replaced with same? Changed size, added sea-cocks, eliminated, etc?

I have searched. Sometimes it is tough to sort through all the bull to find what you need.

Must be cold...everyone seems to have lockjaw!

Guess I'll break the ice with what I "think" I know....One garboard drain plug thru transom for bilge. I have one more in the transom, to the starboard of this one...was this the livewell drain?? Two self-bail scuppers...I think these are brass, one peice with flared ends from deck to bottom of hull? Seems some replace with "ping pong ball" style? What size would I need? From where? Or is this not right? Next, I think the bilge pump outflow is on the starboard side, towards stern. What are the two on starboard side towards bow? One looks like the scuppers (from bottom)?

And what seems to be a good source for all these with fair prices?

I think the thru-hulls are going to vary from year to year and mfgr to mfgr. I have an '83 20sf made by Seacraft Industries and it has the two in the transom for bilge and livewell, but the livewell plug is to port of centerline. I also have a factory clamshell/seacock about a foot forward of the transom and an in-hull transducer (long abandoned). While some of the Potter Hull cockpit drains exit through the bottom of the hull, mine exit through the transom just above the trim tabs. I also have a thru-hull drain at the forward fish box, two bilge pump outlets, one port, one starboard, and a live well pump outlet to port.

Just replaced most of mine. `89 20sf tracker hull. Bottom = bilge. 2 just above and slightly outboard. Starboard= livewell inlet. Port= livewell end of day drain. . Just above and to port was 2 3/8 O. D. livewell overflow. Weird size. Had to make a glass sleeve to make up the 3/8" Mine were all plastic. Now all bronze. The inlet hole was not properly aligned and was a challenge to straighten relative to the transom angle for proper bedding. Also had to sleeve w/ glass. Thru hull starboard side is bilge pump out. Forward fish box starboard self bailing drain. I installed a clamshell pick up for my new livewell just behind my gas tank 9" port of keel Tuff gel and 5200 to bed and help prevent galvanic corrosion.
