Hi all,

I was out boating this weekend cruising along when my starboard engine just quit. I noticed when I opened the engine hatch that there was a black oily substance leaking from the fuel pump. I pulled the fuel pump which is mounted to the sea water pump and noticed that the little cam roller in there spins freely, should it do that?
