While performing fluid level checks for trip home from greenport, NY to east patchogue, NY (3.5 hr voyage) I notice port engine coolant overflow receptacle full. Most likely have raw water intrusion. Trip to greenport was uneventful w engines operating at 170 deg. Coolant color appears a bit diluted and just thinking, after fueling up midtrip, exhaust appeared to "roar" a bit and felt slight vibration. Not sure if this is relevant. Have decided not to take any unnecessary risks and will leave her in gport for mechanical inspection on Monday. Any thoughts on why this would happen would be appreciated. Thx in advance!
