Engine Diagnostics Question

The check engine light came on last night. When I checked the diagnostics it read "IAT higher than expected 1" I assume IAT means Intake Air Temp. Any idea what would cause this or what I should be checking for issues? After shutting the boat down, turning off the battery and restarting the light remained off for the rest of the night.
Also, just out of curiosity how many hours do you guys typically put on your boats in a season? In just over a month we have already reached 25 hours and need the break in service. Hard to believe how quickly they add up!
Thanks for the help!

My check engine light went off at 25ish hours for coolant temp. It reached 200 degrees and threw the alarm. Come to find out ilmor had a bad batch of thermostats. My dealer has had several boats do the same thing that were all built around the same time. Mine has not messed up since.

Interesting- our coolant temp set off the check engine light a couple hours ago. But hasn't since. The boat was setting under the lift idling with someone in front, which we believe pulled the back end out of the water enough to raise the intakes out of the water. It hasn't repeated this since. Did yours go off or did it continue to do the same thing?

It went away and never returned.

Good to know- any other suggestions on checking for obstructions or anything like that?
