Now that that's taken care of, I'm curious as to how difficult it is to change out water pump parts (i. e. impeller) on this motor. Is it a two hour type job that can be done with hand tools? I'm pretty mechanical, and I'm curious about any particularly difficult things that occur with doing this.

My reasoning for doing this is that I only have about 2-5 lbs of water pressure at idle, and full trim 5500 rpm I have about 16 lbs of water pressure, and these numbers seem low.
