    3.0L Merc ? What hoses are supposed to get warm/hot running on muffs...-gctid821612

    Took out the thermostat and tested it in a pot on the stove with a thermometer. It opened at about 180 degrees. When I'm running my Bayliner 175 (2004) with a 3.0L TKS the large hose to the left of the engine gets hot the other 2 hoses seem like there is nothing running thru them. I've let it run for a long time. Is this ok?
