Or just turn a plastic cylindrical spacer and epoxy it in?

Scott,

I contacted Crane back when I removed the K600 motors because it was pretty obvious they were going to have to be replaced and they were more than willing to manufacture an exact duplicate for $1800 per seal.  The replacement is an 8-1 which was going to cost $1000 per seal.  That's one reason I scrapped the existing motor configuration and decided on fixed minn-kota thrusters.  I purchased four 101# thrust minn-kotas for less than the price of one Crane mechanical seal.
