Thanks for the advice and photo. I installed the fittings a few days ago. The package came with 3 different sized fittings (3/4" 5/8" and smaller one). I used the 3/4" fitting in my reverse cycle air conditioning intake line and the 5/8" in the raw water intake line. The entire package of fittings was less than $4 at the auto parts store.

Here's the link to the picture on the c320 website of our winterizing engine
flush port.
It's after the filter. To winterized or just run the engine for a while:
* close the thru hull,
* i use a 5 gal bucket with a garden hose fitting coming out the side near the
bottom. With the bucket in the cockpit and a short section of clear hose with
garden hose fittings on each end, it connects the bucket to the flush port.
Clear hose is good because you can see water or antifreeze going through.
I run a water hose in to fill the bucket and adjust the flow so it matches what
the engine sucks out or adjust the engine rpm to fine tune. It's easy to run the
engine for 15 or 20 min this way.
* then to winterized, shut off the water supply to the bucket, let the engine
drain the bucket, then pour in a couple gallons of rv antifreeze. Let the
engine run 15 or 20 seconds after no more water comes out the exhaust to drain
the muffler and you're done.

Brass will dissolve very quickly in marine environment. Unless it says bronze
and sold for marine use, it is most likely cast brass. In brackish water, a
brass connector on the raw water intake side on a 320 near us developed pinholes
in only 4 months.

winterizing and spring commissioning. In my opinion, there's no need for any

anyone modified their intake hose/connections for this process?
