Agree with Keaton, no reason for high iat's on a boat with the unlimited source of water for cooling. Mine is always below ambient, usually runs around 3 to 5 Celsius and have never seen it get out of single digits even at full throttle. Have to keep in mind though running iat's below ambient can drop a lot of moisture out of the airflow especially on warm humid days. Need to design the inlet tract so there is nowhere water can pool and then get sucked into the engine in one big slug.
