That depends on the boat and the access. You can tell by its location, down low on the engine, that it will be hard to get to. I have remote fuel filters, so there are fuel lines routed right behind the raw water pump---those have to be removed before I can even start the impeller replacement chore.

Re: Cummins 370 6TBA raw sea water pump
How difficult is it to change out the port impeller? Cummins 330hp 5.9
Its easy if you have four foot arms with three elbows each.
I find it easier to remove the pump from the engine and work on it at the dinette...Aaron

Re: Cummins 370 6TBA raw sea water pump
The PORT IMPELLER is a bear to get at. Took me an entire afternoon to get the cover off and then to find it was completely in pieces so then had to hunt down the aftercooler and remove to find all the fins. Ultimately I needed to pull off the water pump only to find that the MOTOR MOUNT is in the way and must be removed first. And by removing the motor mount , then the drive shaft must be disconnected to avoid pressure!!
Had interesting time putting all back together BUT ALL GOOD.
My next adventure was spotting PINKISH FLAKES coming out of my starboard exhaust into the water. My mechanic said it was not diesel fuel because just put a new fuel cooler on. And then noticing that the water didn’t really have a fuel type shine in the surface so decided it as the pink transmission oil cooler fluid.
HAPPILY that cooler sits on top of the engine and will be an easy fix!!!!!
