More Winterization R27 OB

[Bob&Jilly]

Getting ready to winterize my R27 OB which I will be keeping covered on my farm. Question, it would appear that since my head uses water from the river, it would appear that once I take the boat out of the water those lines will drain. Is that correct?

There is a strainer inline that will need to be flushed with antifreeze, also your raw water pump for the wash down in the cockpit will need to be flushed. But I live in California so don't listen to me, Martin (Channel Surfing) has a video about it:

Thanks, I get that , I was just wondering that if the river water is used for the head would it just drain when it it out of the water after a flush.

Not all of it. Doesnt take much to Crack that nice porcelain bowl.

Thanks I can always flush some antifreeze into it.

We follow Martin (Channel Surfing) video to flush with pink RV antifreeze. I keep saying I'll fabricate a better way, but so far, I've inverted the strainer (with sea-cock closed) secured a 1-gal zip lock with a rubber band (after cutting off a corner) and poured in as my wife flushed the toilet until it shows solid pink inside.
if your "stored" at a fairly steep "bow up" I'd assume it would drain as well, but my OCD would worry!

Interesting, since the toilet draws water from the sea, won't it neceaaril drain if the sea cockis open if the boat is out of the water?

I've done it both ways.

In the water, I've shut the seacock, opened the strainer, pushed RV antifreeze through it while flushing the toilet until I saw pink, and called it good.
Out of the water, I've left the seacock open, removed the strainer and let all the water in the line fall into the bilge, then flush the toilet once. This drains it.

Since I had my toilet completely apart on my bench at home this season, I know exactly how water flows through the toilet. Water that would be trapped in the toilet is in the water pump, which is a diaphragm pump, and is then pumped up in about 8" of flexible hose to the top of the bowl (you can see this hose on the back of the toilet).
It'd be easy enough to pop that hose out of the toilet water pump and let the water fall out of it. Or just keep a heater on the boat, and the head door open to keep the cabin and head temp above freezing.

Since we boat year round, and are stored out of the water at Dagmars Marina, this year I'm running RV antifreeze through my raw water system to get the raw water wash down pump, strainer and hose filled with antifreeze. The toilet side, I'll just open the sea cock and the strainer to drain the water when I'm out of the water on blocks, and will keep a heater in the cabin to keep the head above freezing.

On our 2023 R27 OB, I made a “flushing bowl” out of a spare strainer bowl. To winterize with “pink”, I connect a bucket to the flushing bowl via a hose. The bucket has a hose bib in it. With the bucket up on the grill lid gravity can help. I use this for the A/C and deck wash. Our head is fresh water flush.

THANKS!!! where is the strainer located?

The strainers are in aft section of the cockpit’s center compartment on the luxury model: port for A/C and starboard for deck wash.

The strainer I'm referring to specifically is the on the raw water wash down pump. Stand in the center cockpit looking aft. It's located on the starboard side, aft, next to the engine battery, but is best accessed from the center cockpit. I want to run RV antifreeze through it so it doesn't freeze/crack.

The other strainers are the ones in the center cockpit, aft, next to the seacocks.

 

[serendipity]

I misspoke! The A/C strainer is on starboard and was down strainer on port. Martin is correct. The strainers are just off the through-hulls in the aft portion of the center cockpit compartment.

That spare strainer bowl idea is fantastic! Makes winterizing a one-person, rather than two-person job. I've been looking for one of those strainer bowls online and they are not inexpensive...at least $50, unless you have a source I don't know about....?

 

[serendipity]

You are correct about the cost. However, if we amortize it across several years of use the “investment”, it’s not so bad. Being able to DIY boat maintenance helps .

Yes, I agree...it's not all that much spread over multiple seasons. I will also be able to use it to treat the head and washdown with vinegar when they get that funky raw water smell.

Do you have any details on the parts you installed in the bottom of the strainer?
