With all the great information

With all the great information I received with my outboard troubles I've got a question for a friend. He owns a 99 60 horse merc tiller steer. I'm not sure the hours but if the weather permits he uses it at least three to four times a week year round. We recently put a new impeller in the water pump. If he lets the motor sit at idle speed in neutral for over a minute or so the overheat alarm comes on. Also the motor doesn't pee when in reverse. Any Ideas?
 
There might be too much exhau

There might be too much exhaust in the water. Put the motor in gear at idle and see what happens.
