I have a 1976 9.9 Johnson and every time I run it rubber appears in the 6 exhaust holes above the prop. I take off the lower unit and clear it out and look up the exhaust and doesn't look like anything is wrong. I go to start it up again and more rubber appears. Any idea what this is? It's not the impeller.
