Works real easy!

Just above the water line on the port side by the salon.

For seating the through on the out side should I use 3M 5200?
I used 3M 5200? before on a through hole but am thinking of something a little less permanent.
Thanks,

There are very few places I would use 5200 on a boat this is not one of them...I think you should have to have a licence to buy the junk...

Maybe for mounting your seacock backing plate but not for bedding the mushroom head through hull fitting itself.

Why would you want a holding tank macerator pump out ABOVE THE WATERLINE... Do you really want/like having a stream of **** running down the side of your boat??? I would highly recommend filling in this hole and putting in a proper seacock and through-hull that exits UNDERWATER.

Better yet, take the discharge hose from the head and run it directly into the holding tank and use the seacock that the head was using for overboard discharge for the macerator discharge, and you can get rid of one 1/2" hole through the hull completely.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.

bljones has a spectacular aura about bljones has a spectacular aura about
using a small hole saw inside a big hole saw on the same mandrel is fine, except that a) depending upon the quality of your hole saw set, the mandrel may not accept two saws at once, and b) if you size them carefully, you may find that the small hole saw will not be proud of the larger hole saw, which leaves you right back at square one.

Have you ever heard of an Oops Arbor? It is specifically designed for what you want to do. It will hold both hole saws in place allowing you to cleanly enlarge the hole. It is an inexpensive and handy tool to have. Hope this helps.

Saildog...too funny...your red and blue oversize writing is exactly what I though when I read the discharge was above the water line. I was picturing Wile E Coyote with a clothespin on his nose hitting the Acme switch and discharging wondering why it still smelled when he sailed away from the mess.

Best scenerio....head to holding tank..at the bottom of the tank where your out put usually is put brass valve which closes so the s...t stays in your tank and doesnt sit in your lines until you want to pump out ...after that a Y valve..one side goes to the deck pump out and the other to the macerator and then to the thru hole under the waterline.

The trick with the valve at the bottom keeps your lines clear and will help them last longer ( Its a bitch bending and replacing the good sanitation hose).

There was a article in one of my sailing mags recently, I think it was Good Old Boat? IF, a big if, I remember right, the suggestion was to cut a hole in a piece of plywood using the old size, in your case the 1/2", then put the cut piece in the new hole saw, I guess it acts as a guide. I have not done this, and would be scared sh&tless doing to a hull of any boat (except a maybe a Telstar 28) so maybe try it several times on something else first or do what others have suggested. BUT I have to echo Sailing Dog...why the heck would you want it above the waterline? So much for lunch

I don't recall it with the interesting name ...... but I purchased and used one a few years ago with good results.

Hi,
Made a mistake.
The hole size is 1” not ˝”.
The through hole is still in the boat so I am not exactly sure of the size. A 1” hose fits over it.

The new hole size will need to fit a through hole that a 1 ˝ inch hose fits over so I am thinking a 1 ˝ through hole.

The same situation still exists and all the ideas are still the same I think.

The macerator through hole is located at the waterline. I can bend over the dock and put my hand up against it, as I have done it when checking the macerator. No waste would run down the side or at least only an inch if it did. I cannot remember if it is at the waterline or part is under water. It may even be under water after we get to cruising with all the gear. We macerate when sailing. We are moving so it does not catch up with us. We did it once heaved to and never again, that was on our old Catalina 30 and the through hole was under water but still the odor was bad.

So I could see that when cruising we may be at anchor and need to pump out so underwater would be better.

To move the through hole below the water line I would need to drill yet another hole in the boat. Leave the one that is there because to take out the through hole and fill the hole and re-do the waterline is a lot of time\work and we have way to many other projects going to take that on. Besides our sh… don’t stink!

The toilet out through hole is in a bad location, under the master bunk and hard to get at. We do not use it. We put in all new waste plumbing and holding tank and toilet. We use fresh water and the holding tank.

I had never heard of the “Oops Arbor” but just looked at one on Amazon and looks like it will do the trick. I am definitely getting that tool. Seems like the answer. I am not sure if my hole saws will work with two together.

There have been a lot of good ideas and I am glad I asked.
Thanks,
Chip
