Very nice filter head / water separator combo. Filter head seems to live up to its marine rating with a very nice thick coat of paint, and well milled sealing surfaces.

I am using this with my Yamaha 150 on a Challenger 187. It mounts easily inside the bilge, and now I have a good water separator in case I ever get any bad fuel. The base is aluminum, and built tough with lots of options for hooking up the fuel lines. The filter is a standard Mercury part, and the separator bottom is clear for easily seeing if you have water. There isn't too much going on inside the clear part, so it should be easy to keep it clean enough to see what's in there.Love it!
