That is the only metal in the water (excluding rudder p&g). I don’t think I have an actual anode anywhere on the boat. I need to get her hauled out an painted. My plan is to address that fresh water outlet at that time. I may actually close off the thru hull and send the water to the bilge pump. Seems like a bad idea. So does having just that one thru hull.

All bonding systems need an anode or the least noble metal becomes one afaik. So, if it is the only through hull, then it is your boat's anode, by default. Sort of...

Noted on your boat, it is not bonded or tied to the grounding systems and it must be.

If you had another real zinc anode in the system and were tied to it, that zinc would do all the corrosion.

Once your engine is back, the aluminum on it will probably become the least noble metal and corrode, but because it is not tied to the thru hull, the thru hull will also corrode. Unless your ob has zincs..then they would be the anode for the boat, if connected to the other bonded items.

Anyhow, I know enough to know that isn't right, but not enough to sound half intelligent.

Your outboard also needs an anode and if it doesn't have one; get one and tie it to the boat's bonding system.

I have to research if my outboards zincs need any special attention or if the battery is enough.

My skiff has zincs with a ring terminal to connect to the boats bonding system, but I never bother in freshwater.

The merc 9.9 was set for salt and is getting new anodes while in the shop. So they tell me. We shall see.

If I keep that thru-hull it will be replaced with simple plastic with a screen on the outside. what I really want to do is just seal it closed and run it out the back via a pump. but that seems like a bad idea. The only thing that goes through it is the head freshwater sink and the gally freshwater sink. I don't see the point though. Just replace with plastic and call it done.

Is it a drain?

Is it below the waterline?

Not a fan of plastic thru hulls below waterline. If they break off....

Yeah... it's a drain. all it drains are two unused sinks. I could put it above the water line as both sinks are high enough. At some point that entire thing needs to "go away" and be relocated to an area that is less likely to get whacked by stuff in the void (where the engine used to be is now storage and things will be in/out of the area regularly).

Anytime a drain can be above water; do it.

But always install a flexible fitting and always use a p trap to keep skeeters out of living spaces.

I've never seen real P traps on little sailboats. Everything just goes straight to the drink. Also, no ridged plumbing. Remember that these suckers roll like sweet corn in butter at a southern family reunion. if you have any water in a line it will be out the drain and back into your cabin pretty quick. On the J we had to shut off ALL the stop cocks undersail as water would go the wrong way. If you need to use the head, there was a procedure list...
1. Do your business.
2. open line to black water tank.
3. Turn on head pump
4. open raw water line
5. count to 5
6. rotate pump handle clockwise
7. pump till your business is gone.
8. close raw water line
9. rotate pump handle counter clockwise.
10. pump till empty
11. close black water tank
12. turn off head pump.
13. You know you made a mess... clean it up.

It was crazy to see water coming up the gally drain underway. But that's just how it worked once you had that thru hull buried and the boat started into the rollers. the sink was just above the water line so a large wave would raise the water in the drain. I can't wait to have that problem with Lil Bit More.
