The "great broad" was out playing tennis, but I will try to help.

The thermostat is under a cover with three screws at the top of the cylinder head.

service the water pump, new hoses, they are 35 years old, probably a carb kit. http://forums.iboats.com/showthread.php?t=158086

Re: NEED TO NOW 1970 25 HP Evinrude

The 378065 thermostat is 143 degrees F.

You should be able two keep your fingers on the cylinder head for a full three count anytime the engine is running.

The properly functioning thermostat will open and allow water to flow out of the cooling circuit whenever the cylinder head's water reaches 143 degrees +/-.
