[C320-list] raw water intake modification

[Jeff Hare]

Yes, the fitting has decent length barbed parts. Plenty of room for double clamping. Plus, it is pretty inexpensive and available most places that sell prestone antifreeze like walmart, auto zone, etc.. it comes in a small kit with a few different sized t fittings and parts, but I only used this ont 5/8" T fitting.

Thanks Jeff. I assume that the fitting has barbs going into the inline hose? I hadn't considered splicing in downstream of the filter, that may solve the problem of the really short hose run from the thru hull to the filter.

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.

anyone modified their intake hose/connections for this process?
