Sorry to hear about the knee Ray. One of God"s speed bumps....Hope it's nothing major.

My buddy Stanley's boat motor quit "peeing" out of the indicator. We had to disassemble some of the small cooling hoses that feed the indicator. There was a plastic tee in the lines that had clogged with sand and debris, probably from running motor in sand/mud when he beaches boat on shore and cat fishes out the back. Anyway, just because indicator is not peeing doesn't necessarily mean engine is not being cooled. Are you getting high temp buzzers or alarms as well?
