[C320-list] Oil change on the hard

[Jeff Hare]

Bob,

That's what I do. The best thing is to have a shutoff on the end of the hose that let's you adjust the water flow so that it doesn't overall the bucket or not fill it fast enough. 

I run my engine for ~30 minutes that way and then shut off the water, when the bucket is empty, start pouring 3 gals of rv antifreeze. When that's gone I run the engine for about 20 seconds after the water stops coming out the exhaust. Then I usually find the exhaust is empty and nothing left to drain from the muffler.

The rv antifreeze lubricates the impeller so no worries about the short time without water.

My alternative was to provide water via a bucket in the cockpit with a 
hose leading down to a T fitting I installed inline with the raw water 
intake hose (to simplify adding antifreeze to that part of the cooling 
system for winterization) some years ago. Should that work?
