lubricate the inside of the pump's cylinder and piston I have no other

then to take the pump apart. Maybe someone has a better way to lubricate
the moving parts.

No need to take the pump apart...just remove the top. And on a Jabsco,
it's easy: on older models, remove the 6 six screws and lift it...newer
models, just loosen the hex nut and lift it. Put a healthy squirt of the
grease into the pump...pump a few time to spread it all over the inside of
the cylinder...replace the top. Should take all of 10 minutes, if that
long.

I just serviced my Jabsco and it made a world of difference. I removed the
6 screws and pulled off the top. I had a bit of water trickling past the
inlet valve so I closed the seacock. I then used a small diameter
toilet-type brush and warm soapy water to scrub out the pump cylinder. I
then filled the cylinder and toilet with vinegar and let it sit overnight.
Used my wet/dry vac to suck out the vinegar next day. Dried out the pump
cylinder with paper towels. I coated the pump plunger with silicon grease
and also the cylinder as far down as I could reach. I put in the plunger
and worked it a few times and then repeated the grease application. Now I
can operate the pump with 1 finger.
On the silicon grease, I have some old laboratory silicon grease that was
used on glass-to-glass joints. I tried using silicon grease from an auto
parts supply store, the stuff they put on rubber bushings in car
suspensions. It didn't work too well as it was quite sticky.
