Haven't done or heard it being done on anything but a house boat
Those units work pretty well but do need cleaning even in fresh water due to build up inside the coils
Always helps a bunch to tell use what your working on. Found the pump in manual 5 for TR and TRS drives
The thing just to the left of the right trim line is a dipstick and fill point
Fill with 10W30 or 10W40 oil
New to you boat I wouldn't chance it. Once you have run the boat for a season and checked it out then that would be ok. The fuel consumption data may be correct for new, but don't know right now
If you do go, pick up a loaner EPIRB in case something happens

The senders "should" (I say should) have port/starboard on their sides
Both senders use the same wires so if your sure you have the wires for a given side, and the meter is connected on those same two wires, thenyou have a bad sender
The solids will be the main issue. Can put chemicals in to reduce the smell. If it stays with mainly liquid (paper in a trash bag) you can pump it out your self with a shop vac. Then pour it down your toilet at home
Hand caddy and rental boats, things like LEO/USCG/USACE come to mind.
Don't see a way out.
Suggest, figure a base cost and don't use a refill.
Boat A uses X Gal per hour.
Boat B uses Y Gal per hour.
Take an average and base it on time not Gal used. Don't get into the weeds.

Mercury Vesselview will show fuel usage/remaining but its just calculated from the boat/motor sensors. It knows how long the injector pulse width is and can guess on the amount of fuel used. It doesn't know if one injector is supplying more or less fuel then the other.
It's the age old thing of it has to run better on high octane fuel, because its high
High only means it burns slower, so if timing is set for low then use low because it burns faster
Always use what manufacture requires for best performance
If the senders are installed correctly (sender starboard, switch port) and your getting no reading using just the 2 leads, then sender is bad. Do rotate it all around to make sure.
The switch will show a connection (zero ohms) until it opens
Not getting a beep, check fuses on the motor.
There is also relays (small square boxes), have someone turn the key to ON and another feel the relays to see if they energize
Use a voltmeter and measure power at the main power relay or fuse to see if your getting power when key is turned ON
