It looks like it can be done, however tough to replace the small seal and then line up the wear plate and bolt holes and impeller.

Easier to pull the pump. You will want to change the fuel pump lube too because gas always gets in there.

It can be done, and I imagine on your center and/or engine(s), you do not have much clearance to pull things off the motor forward. You really do want to remove the whole pump. You would be forced to bend two very stiff hoses (intake & discharge) to remove them from the back of the pump housing, and they are on plastic barbs. You will likely crack one or both of the plastic barbs while trying to attempt this. It's in your best interest to pull the whole pump/pulley assembly forward to remove it.

Got to it, this afternoon. Removing the hoses was a piece of cake. I wound up leaving the pump on the engine but I did loosen the tension on the serpentine belt and that gave me enough wiggle room to disassemble and reassemble everything without a problem. Tested out on the water today and all good.. Very easy to do..

The lube reservoir is most likely full of gasoline. Changing the oil is part of the job.

Very true, both mine were full.

Also, if you take all 5 bolts out to change the impeller, the pump is off the bracket / motor. Unsure then how it was done with removing.

Pump was left dangling but held in place by the belt. I just loosened the belt to re-assemble. I took the fill screw off the lube reservoir and there was oil in there, not gas, so I left alone. My pumps were all redone at the beginning of the season. My starboard water pressure gauge has been jumping around a lot and I also noticed some inconsistent water flow out of the exhaust. Thought it might be a bad impeller. Engine temps have been fine but changed the impeller just in case..

I think I'm going to do the other pumps now.. But this time, I will heed your advice and remove the pumps entirely so I can change the lube. What do you guys use to plug the fuel lines?

Mine is rubber and I stick a tapered punch in it.

guys I have easy access to the back of my pump to change the impeller, is there any reason I should still remove the entire pump to do it?
