Your thoughts are quite true! But in my experience with analog transducers (some as expensive as $225 ea.) used in race marine environments. Which can take as much as 5 G's (accelerometer measured) of load are, that they fail quite frequently. Not to mention the problems with salt water and inherent corrosion in electrical connections. But your idea has merit!

Flyfast,
You should always run your engine at the recommended oil level on the dipstick. In fact it's a good idea to get the actual oil capacity from the marinization manufacturer completely drain the engine with it being level and start with a new filter. Then fill the engine with the specified oil quantity and run the engine for at least 5 minutes and then verify the dipstick "full" level oil mark under the conditions you would normally check it. (eg. floating at rest, on your trailer attached to the car or on a level, etc)
Reason being is that the marinizers cannot possibly have a dipstick that is dead accurate for all installed angles of engines and dipstick assembly tolerances.
So .... they usually error proof their recommended fill level by edging towards being overfilled if anything. Because of this if you run an additional quart full you will most likely be areating the oil with the crankshaft and creating excessive windage (power) losses in the engine. This also creates undesireable stresses on the rotational mechanism of the engine. In addition the areated oil can reduce oil pump and oil effectiveness.
Many racers actually reduce recommended oil volume content until they notice oil pressure start fluctuating due to low oil volume during actual boat runs and then add a half quart for safety margin and remark their dipsticks.
So unless your into getting the last ounce of power out of your mill .... stick with the recommended fill quantity and verify your dipstick full mark integrity.

Great reality check HelmPilot. We are not there yet, but similar to EFI, it is only time before it is reality. I'd think vibration would be the main stickler to connection and conductor integrity... not necesarily g-forces. Food for thought for me. Thanks, I love this $hit!
