  1. Hi All, I have a 2005 (bought new in 2007) 298SS with dual MCM 350 MAG MPI Horizon engines with Bravo Three drives and only 107hrs. My port engine (connected to hot water heater) is overheating and there is no water coming out of the exhaust exit. From my understanding this is a Closed Cooling system that uses sea water to cool the anti-freeze (heat exchanger?). I am early in my diagnosis and have only verified that the seacock is providing water to the seawater pump and the drive belt looks to be in excellent shape. My next items to pursue is seawater pump (impeller check), thermostat, heat exchanger (wire brush?) and exhaust eldows. Is this still the direction and order I should continue with or is there a better order for expected repair/clean/replacement?
