Hi. Recently I found a fair amount of grease/oil (odorless) that looks
like it was sprayed out from the pulley of my seawater pump (92 merc
454 bravo one). Now my fuel pump is not pumping. I'm figuring I blew
the bearing in the seawater pump and burnt out the cam driving the fuel
pump. Sound right? Any chance it could be something less dramatic like
just the fuel pump or a gasket? I am going to pull the fuel pump and
check it out so I guess I really won't know until then, I'm just
wondering if anyone has had this, I can't find as much as I'd like on
it.
Assuming the seawater pump needs to be removed how much water will come
out of the intake hose to the pump when I pull it? I'll have to do it
on my mooring. What's the best thing to plug it with if the water keeps
coming? I don't have a cut off or seacock that I can find. My only
concern over the project is spraying salt water all over the place.

Thanks for any thoughts.
