Update:
It's raining and 53° so the installation will have to wait until tomorrow.
I now have in my possession a complete new pump.
I "borrowed" a pulley puller kit from AutoZone. Their program allows you to buy the tool with the expectation of returning it for a full refund.
The puller worked well so the pulley is off the old shaft.
I expect it to be easier to install the pump first and then add the pulley. A practice installation with the pulley tool showed me it will be easy to do.
Mercruiser telephone support gave me some tips:
A touch of motor oil on the pulley shaft.
Dish washing soap will aid in hose installation.
Some torque specs.
The new pump assembly is better because it has a circlip to retain the shaft in the housing.
My flushing earmuff flood abatement was adequate for removing the pump but I will augment that with the trash bag technique suggested here (thanks).
If any of you up in Wolfboro hear a tirade of cussing tomorrow it will be me down here in Paugus Bay applying some "verbal lubrication" to the task.
