The best way to check temps and I do this every season is to use a contactless infrared thermometer. You can get a usable one at HD or similar for about 30 bucks.
With the cowling off, you run the motor and using the thermometer, measure the temp of the thermostat housing. It's not critical where you point the laser beam but make sure that you point to the same spot on all the t-stat housings.
You are looking for two things: higher than normal temps ( or colder than normal) and a significant difference between cylinder banks ( if there are two of course)
I can't tell you exactly what temps you should see. Over time you will learn. Most thermostats open in the range of 145 to 165 or so.
In the absence of a thermometer, you can put your hand on the t-stat housing or head cover as the motor warms up. You will be able to feel if there is a big difference but note that at some point the metal may become too hot to touch!
If the t-stats heat up differently , one cooler than the other, it could mean that one side is hot OR one side is colder than it should be. Having a few reference measurements over time will enable you to determine if things ate too warm or too cold. here
Many years back, I was in a store listing to two fellows argue about who's boom box was louder. One of them said, mine is so loud, they numbered the volume know from 1 to 11 instead of 1 to 10.
My point is that 65-75% doesn't mean a lot when you don't know what it represents in absolute values. Those kinds of displays drive me nuts. [links]
Saltwater corrosion is non biased. It pays no attention to manufacturer, model, or year. I'm not implying corrosion is your issue here, just stating the facts. Im not experienced with running twins so I can't tell ya if it's abnormal for one engine to have corrosion when the other does not. Perhaps someone who runs twins can comment about that. But it wouldn't surprise if it does happen. See my first statement as to why.

Just for S&G's, did you check the LU pick up screens for any debris?
Is there a noticeable difference of T/T stream between the 2 engines? If you're uncertain, run both on flush. Hold an empty water bottle at the same time under each stream. Theoretically they should both fill up at the same time, so long as both engines are receiving the same amount of water pressure. more
And I know the thermostats are new, but did you actually test them and see if they open at the expected temperature? Maybe the ones you installed are just defective. Unlikely, but what you describe (overheat at idle, fine at other speeds) sounds like a sticky valve. Thermostat or poppet valve maybe. [links]
Did they actually measure the temperature with another instrument, or did they just look at the YDS output on a computer? If the latter, then it still could be an issue with the cooling water temperature sensor (as opposed to the thermostat). [links]
Some cars use the engine coolant temperature sensor to control the electric cooling fans. You have two separate temperature sensors for the fans, dashboard gauge, and engine management in most cars.
This article will discuss the most common symptoms of a bad coolant temperature sensor, location, replacement cost, and how to diagnose it.
Different brands and car manufacturers have different ways of placing the coolant temperature sensor depending on the car design. here
