Recommissioning a Cummins 4BT

I am reinstalling a Cummins 4BT in a recently acquired project boat.
The motor has been out of the boat and stored under cover for four years.

Can you give me a brief 101 on what steps are important.
I assume, coolant change, oil change, manual turnover, flexible water impeller replacement.

Any other measures for the engine, not including the drive train

If possible reprime the oil system to insure FRESH oil to all bearings...... with no load on them.
Thermostat replacement would be a good idea also.
