[C320-list] Engine Winterizing

[Chris Burti]

Allen,
Look closely at the cover plate on the pump. If it is worn where the impeller rubd against it, you will get the same symptoms.

Subject: [C320-list] Engine Winterizing


When winterizing Sea Shadow for the first time 5 years ago, I cut the raw
water line about 12 inches forward of the raw water strainer, installed a
3-way gate valve, and ran a hose off of the gate valve into a bucket of
anti-freeze.  I then turn of the engine and turn it off when the bucket is
empty.  Again, I have done this for 5 years with Sea Shadow and 13-14 with
my previous boat with never a problem.

Yesterday I winterized and had a fit getting the engine winterized.  I could
not get the anti-freeze to start flowing from the bucket.  I even changed
the raw water impellor but it was fine and not the problem.  I tightened the
belt to the raw water pump and that was not the problem.  Sea water flowed
no problem.  Finally, after fiddling around for more than an hour, I took
the engine up to about 2500 RPM's, got sea water flowing with no problem,
had the winterizing hose in the bucket, changed the 3-way valve to bucket
mid-stream and was successful at emptying the bucket.

The question is what is going on?  Is it possible that the raw water pump is
giving up the ghost?  Does that pump die slowly or go all at once?  For the
past 19 or so seasons, I always have been able to winterize at idle speed.
Any ideas would be appreciated.  Thank you!
