The job started out with replacing the exhaust hose. Once I got into it the mixing bowl and riser were replaced also. It's nothing like working on the boat listening to the water splashing against the hull with the boat rocking as you work. When it was all done I just sat back and smiled. I did it myself. Thanks to this forum and you folks who give such great advise. This is my first sailboat, she's new to me, Just can't wait for warmer weather.
