I have a 94 johnson 115 on my boat. The water temp is shooting up at full throttle and its peein, but the stream is a little weak. I tried Flomax to no avail. HA HA I was told that it is probably the water pump by a local guy at the lake by me. He also said it could be a head gasket. Now I am hoping and praying that it is only the pump. What do you guys think it is and is it a really hard one to fix myself with a little help or should I just break down and take it to the local boat repair and pay them out the Yin Yang to get it fixed?? If so, where do you guys suggest, I live in Louisville. Any and all help is appreciated!!!!!!!!
