Hello, I have a 1990 Mariner 250. I am trying to figure out why the tell
tale stream does not put out a healthy stream at idle. My temp on the
engine
stays in the lower portion and I have pulled out the thermostats and the
passages are clean. does anyone else have this engine and if so, can you
give me your expirence with your cooling system?

Thanks
Chad



Maybe time for a new impeller. My 15hp mariner gets the pee hole clogged at
times. Is a very small hole.
