I'd add the following to the list:
I check the strainer before starting the engine
check the
coolant level in the radiator (if you have one)
do a visual check of hoses, making sure there's no broken clamps or chafe
make sure the dip sticks (engine, transmission) are secure, the radiator cap secure, and the oil fill cap secure
check the sump pan for any residue. Make a note if there are.
check the stuffing box (I have the old style and keep track of the drip rates)
I start the engine and let it idle:
check for water coming out of exhaust (I've got a one-way valve in the exhaust but many folks have a manually operated valve)
check the exhaust for color, smell, sheen on the water
check the
raw water impeller case - it should feel cold
check the
instruments
check transmission forward and reverse - make sure transmission engages fully and that the controls don't bind
run the RPMs to 1000 or so:
check the
raw water strainer
check for weird noises
check that the
instruments show movement
check the alternator/battery voltage making sure the
alternator is working (at this low
RPM, it may not be putting out much, or any voltage)
This sounds like a lot but it takes me about 2 minutes to do the checks. I'll check the Racors regularly as well as the raw water strainer and
raw water pump case and shaft for
leaks.
