26M- Everything for the kitchen sink!

[adudinsk]

Following another members lead, I decided to have the sink pump out electrically.
I purchased a shower sump, and will be mounting it under the unit under the dinette seat.

I then opened up the hole for the starboard steering linkage, and installed a discharge port.
This will discharge the sink water into the motor well.. then down the drain there.

I will be installing a true sea-cock for the transom thru hull and re-plumbing it so it just connects to the motor well not the sink any more.

Will be installing a platform to hold the shower sump in the next few days. (will post photos)
Used 5200 quick set around all the connections/ discharge port.

When its all done and tested, wife now wants a water bladder, and an electric pump/tap....

That's coming along nicely.

Why the long face? A pressure water system and bladder project will be a great way to pass the time! Plus we'll all get to enjoy it vicariously. You'll not only be doing a honey-do, but performing a public service. Thanks for the project pics! Keep em coming and keep up the good work!

Agreed.. but I wanted to get the boat in the water , and was taking my time doing upgrades
Now have LOTS of time to do them and will be spending more $$, as the Port Authority closed ALL marinas and boat ramps in Ontario.

Cannot even launch the boat and park it in my paid for slip.!

But there are several abandoned ramps... a few 100 ft from my marina, wonder if they would say anything if I put it in and docked it.
And if we are a "club" are we still closed!?

Nuts..
More projects
More Money
Less time on the water.

nice mod.

One question: What is the reason for the sump pump?
And: the seacock valve: When will it be closed? If you close it the motor well you have gallons of whater in it and will no longer be drained...

[adudinsk]

I put a seacock (installing today) for the transom as by ministry guidelines, its legally required (insurance said if I flood as its currently under water, no coverage).
So I will plumb the motor well to the sea cock removing the sink

THe sink then will be plumbed to the sump unit.
the output of the shower sump goes to the thru hull (no valve, as its above water line) and empties into the engine well..
THen flows out through the engine well drain/new sea cock.

No extra holes in the boat.
All now legal /insurance approved in Canada.

Seacock will only be closed when sleeping in the boat, or when docked..
(Again Ministry of Transport requirement in Canada)
All below water holes must have a valve / sea cock if one intents to sleep in the boat.
Insurance will not cover a sinking if there is no valve.

Hmm. You’ll be discharging grease, soap, and food bits into the motor well.

Not sure I’d be entirely fond of that if it were my boat.

Since the M motor well drain is the size of a pencil (almost) will you be installing a sink drain? Mine always gets plugged with small leaves. Thought about replacing with a stainless bar sink drain with a stand off screen to filter debris.

Excellent point! The area is hard to keep clean as-is. It will get pretty gross with that plan. Suggest you rig up an elbow and tube arrangement that you can insert in the thru-hull to direct discharge over the transom.

ok, clear to understand. And how do you drain the motorwell when docked? If the sea cock is closed the motor well will get full of water...

Does the ministry and your insurance company know the thru hull is ABOVE the water line (see pic below)? And that the boat is "unsinkable" with floatation?
I have never heard of this issue with Macs in Canada.

I have to agree with the comments above regarding pumping sink stuff (food etc) into the motor well. We often rinse dishes in the sink. Since you are pumping it anyway, why not just dump it out the transom up higher.

I love your ambition, but I don't know, sump for a shower I can understand. But the food stuffs we put down the sink I prefer to go right over the side (transom) and not sit in a sump basin and start to smell and grow funk.

interesting Russ, my throughull is much deeper. Most of time half under water...

But if a Mac sinks - even when she is unsikable... The waterline rises some feet... This will get some $$$ for the insurance

My thru-hull is also under the waterline (ballast full). I have 2x12gal tanks, a heavy 70hp motor and my fat arse. So I always assumed mine is aft heavy and submerges the thru-hull.

I'm surprised I haven't seen this issue in Canada before. There are many Mac owners in Canada.

I actually like the idea of a proper seacock vs. the glassed-in factory setup that has no shutoff. I need to inspect my hoses back there. It certainly is a failure location, although I haven't heard of a report of one failing.

Wait, that's not true. I remember a captain that had a fuel line leak. This flowed into the motor well into the drain into the bilge. . viewtopic.php?f=9&t=18495

Another user did it here.. followed that approach.
Not to worried about food in the sink.
Just do not want any more holes in the transom. Already running a larger motor.
I was thinking about putting a flush drain in the motor well.. since the marina's and boat ramps are all closed..
i will have lots of time to test the setup.
And modify as needed.

I expect we would use the sink to mostly was hands..rinse glasses.. that kind of thing.
I do not expect a huge dish washing effort by myself or wife.
