[C320-list] head thru hull

That's why I switched to bronze a number of years ago.

Hi Darrell

I had a similar problem with the macerater discharge valve. Problem was
I 
waited too long to replace it as it got harder and harder to open &
close. 
While at sea, 2 hours from the closest port, the handle broke off in my 
hand, which caused the valve stem to crack and allow water in. We
shipped 
about 60 gallons of water before I had the valve wrapped in enough dish 
towels and duct tape to stem the flow enough for the bilge pump to keep
up. 
We got dockside safely and did a temporary repair and order a new
Marelon 
valve. I changed it at my next haul out.

The size is stated in the manual in plumping diagram, I don't recall if
its 
1.25 or 1.5", but Forespar Marine products carries the exact
replacement. I 
removed the 4 ss screws that hold the valve on and screwed on the new
valve. 
It was simple enough and now I pay much more attention to the way all
the 
Marelon valves are working. I order some spares to cover all the
different 
types we have on board, some 90 angle, straight through etc.

My
