Doing maintenance on the boat today and went to check the oil level on the raw water pump. The oil seems to be diluted with fuel, im guessing the fuel pump is bad?
Yeah, it’s damn near impossible to get it all out without removing it. I ended up pulling the pump completely off as well, basically rebuilding all of it. The front seal was leaking behind the pulley, replaced the fuel pump too being that it’s 17 years old.I just did this today on my new to me Merc. Could not get much out the plug, so I removed the fuel pump and sucked the gas out the top. Mine was real diluted almost straight fuel. Filled it up to the plug. I think maybe drill and tap the bottom of the cavity with a pipe plug to drain the contaminated oil and fuel.
