I change the fluid regularly, but have never heard of doing a flush. Can you elaborate? Also, do you do anything special to clean/protect the outer seals?

Filling to the brim each winter sounds like a great idea.

Marine Parts Express in Edgecomb gave me a very competitive price on a new one (or two). I plan to have a backup when I head overseas.

May try to sell my core on EBay.

Just used your butyl tape for the first time the other day, great stuff. Thanks again for bringing that to light.
