I haven't been using my boat that much but while I was using it today I noticed that my water stream from the side of the motor was weak. It doesn't seem to have very much pressure. It made a little spitting sound when started out the water hole like it was stopped up or sucking air for a moment. I'm really not sure. Anyway I ran it up to 3 miles back to the dock and the stream was still weak but running. I put my hand in the water stream to see if it was hot and actually it was on the cool side. It was warmer than the lake water but still fairly cool. Maybe it needs flushed out or something, it had an impeller put in last year. Advice?

1. Does this 91 elpto Mercury have a thermostat?
2. Does it sound like a bad impeller or stopped up?
3. How can you tell if a motor does get hot, do they have an alarm?

I'm sure I'll probably take it to a mercury dealer to check it out but would appreciate any advice. Thanks.
