Merc water-pump-mounted fuel pump
Does anyone know the part number for these? Or even better, does anyone have an old one you want to sell? All I really need is the pump-arm assembly.

Steve,
Pt # 861677T. This was for my GenV HP465/502.
I bought a new Merc pump a couple yrs ago because I thought the diaphram was leaking do to a gas smell in the water pump oil reservior. It appears it is just a normal thing as I see alot of people say same thing. Gas was never in the sight tube, so I suspect it was never bad. I used the new pump arm half only and retained the other half as it was drilled for larger fittings.
I still have the used pump arm mounted on the brand new/never used bottom half.
$50 to your door.

Mine had 2 plugs (upper and lower) on the side facing out. Fill till it runs out the upper plug.
I always removed the fuel pump and drained the oil out completely a couple times a yr and refilled thru the fuel pump opening until even with the bottom of the top plug. The lower plug won't drain all the oil.
