I just got home from a 600 mile round trip to the Fla. Keys and I am seeing steam in the exhaust from the port engine. It dissipates within 20 ft. When cruising at 7 knots I do not see any steam, but at 2400 rpm cruise it is there. The port engine runs 10 degrees warmer than the starboard engine so I am hoping that the warmer exhaust water hitting the cooler seawater is what is causing it. Not holding my breath though, just keeping fingers crossed. I have put about 800 hours on the engines since pulling, cleaning and pressure testing h/e, aftercooler, and trans cooler so I am going to do that next time at the boat, also will check raw water impeller. The antifreeze is about 1 pint lower than it was and if it makes a difference, I only use Cat products on my engines. Does anybody have any ideas for things I should check? Unfortunately, I am out of state on business and will not be home for about 2 months, so I have lots of time to drive myself crazy with worry while imagining all the terrible things this could be. Any and all ideas would be appreciated. Thanks
