I recently bought what I believe is a 6 hp 1979 Evinrude (model # 6904E). The motor runs great, but I have a few questions.<br />1. When testing the motor on the flusher, the flusher was on improperly and the water pump did not pump water for a couple of minutes. However, I have since had the boat on the water and the water pump was working fine. Is everything OK since the pump still pumps or has damage still been done?<br />2. When I drained the lower unit the oil was thick and chocolate brown colored, but I saw no oil/water separation. My manual says water present will show up as a "creamy whitish" color. Do I have water in the lower unit or just a motor that has not had the lower unit changed in a long time? <br />3. When I pulled the propeller, I noticed uneven wear on the inside of the prop and the housing where it meets. Do i need a new prop or is this an indication of something more serious? Also, is there no seal behind the shear pin that can be checked without disasembling the entire lower unit? <br /><br />thanks,
