[C320-list] Dry bilge?

Been away from the action for a while.  Agree with Jeff on the GFO solution.  As I have said many times in the past on posts, the best $15 investment ever made on my hull 894 (2002) was the Gortex GFO packing.  I replaced the OEM packing with the GFO and bilge has been dry since installation which is about 10 seasons.  After launch in the spring readjust the packing gland in the slip after a few minutes underway with the engine on to no drip and that is all.  Occasionally feel the packing gland after motoring and it is just a little warm and no drips.  Maybe this spring will replace the GFO out of prudence.  I still have some left from the original purchase. Check out http://gfopacking.com/ <http://gfopacking.com/>
