I have a late model raw water cooled A4. I replaced the impeller for the first time in three years. The old one was in good condition, with no broken vanes. Coolant flow and temperature has been fine for the whole three years.
I'm doing the ICW to Florida in a few weeks, so I replaced the impeller. A couple weeks ago, I pulled the boat out, painted the bottom, and made sure the intake strainer was clear. Now, I get almost zero water flow and the temperature quickly goes up to 190 F once I start the engine.
I removed the water pump cover plate and removed to make sure it was installed correctly. Everything seems to be installed correctly. I started the engine again, got a dribble of water, and then nothing, following by high temperature. What could I have done? What could it be? I'm thinking blockage somewhere, but how and where?
