As I was replacing the impeller and the thermostat on my motor - Force 75 HP - 1998 - I found the thermostat housing empty and it looks like it is from day one - no thermostat in it. I went to the Merc. dealer and the guy said as per the serial number of my motor there should be one in it - have you seen something like this before ?<br /><br />Thanks<br /><br />Smoky
