As painful as it may seem to go through the endeavor ofreplacing the head and hoses, it is worth it. One thing I would add is that if you are going to go through the troublenot to forget the air vent hose. I wasstunned to find the condition of the old one when I took it out. In addition to the smell of the hose and theamount of gunk built up inside, I discovered that it was pinched nearly closed bythe 90[SUP]o [/SUP]angle that formed coming out of the through hull. I made sure to snake the new one around the pumpout hose so gravity and integrity loss does not cause this in the future. I’m convinced now that this pinching was contributingto some flushing problems I was experiencing. <o></o>
