Hi All, I have a 93 baja with a 454 mag ho GenV second or third impeller change I noticed water in the mech. fuel pump reservoir and the bearings were going bad due to water in them rust etc. removed pump and replaced bearings with sealed units and removed mech. fuel pump and blocked off with plate and added a Mallory 4-8 psi electric fuel pump. 2-3 years later I am replacing the impeller again and find traces of water in oil reservoir which was dry since the removal of mech. fuel pump. I also noticed when engine/water pump is not running and hose is still connected to water inlet hose a fairly nice 1/8 inch stream of water shooting out the weep hole in the side of the pump just in front of the mount area.
I use a custom made fitting that connects to the garden hose and then connects directly to the inlet hose that I remove from lower unit at transom wall after an episode with the muffs falling off while running it by myself and lunching the impeller. I realize that is pressurizing the inlet and the impeller area of the pump but should water be passing thru the bearing area into the reservoir where oil would normally be? I would think not but this is obviously happening during normal running conditions or there wouldn't be rusty water in the reservoir area. What path does bypass water take to get to the weep hole if it's not going thru the bearing area? Thanks for the insight
