After running across the lake, I slowed to cross a large wake. When I slowed, I noticed a knocking noise coming from the engine. I turned the engine off and removed the cover to inspect. Everything looked fine. I cranked the engine and it still knocked. I figured it was a goner, so I ran at 3000 RPM back to the marina. As I idled through the marina the noise faded. Finally at the dock, the knock had disappeared. In neutral, i ran it at 3000 rpm for about 30 seconds but no knocking. Back at home, I hooked up the garden hose and ran engine tuner through the engine thinking i might have carbon build up. After sitting for several hours, I ran it several minutes at different RPM's and still no knocking. It clearly was not a lower unit noise. Any ideas what it could be?
