I found this photo from two years ago when all the original Marlon valves on their threaded thruhulls were replaced with the "newer style" Forespar base-mounted valves. The new ones are epoxied to the backing plates. The marlon threaded thruhull pipe is screwed in from the outside, and bedded in epoxy, and then ground off flush with the hull.
The photo shows the bottom of the boat, under the berth in the aft cabin, facing forward.
The PSS dripless seal installed in 1995 is visible on the left.
The hose from the valve goes slightly out of this photo on the right side as it makes two 90 degree turns to come into the top of the Groco strainer. The exit fitting from the strainer goes forward, along side the Universal M25XP diesel, and to the raw water pump on the face of the engine.
The original Morse control cables are visible, as is the coupler to the back of the trans.
There has been some comentary on the Sailnet/Ericson list lately about strainers, etc. Note that this strainer is actually suspended from the top of the frp berth bottom with a custom frp 90 degree piece fabbed up by the boatyard.
With the access lid off, I can get to the valve and strainer easily.
Note also that this is the "engine flushing" valve with the garden hose fitting on the top. When the handle is put over 180 deg, I can put a short hose on that fitting and run antifreeze thru the raw water part of the system and the heat exchanger to winterize it.
I hope this helps others visualize the setup a little better.
