Hi All , Got my 1967 Evinrude 3hp fired up today. Gas oil mixture 24:1 motor started right up but after running for a few minutes it started to screech like metal on metal. Shut it off immediately . Turns over fine, pulled the side cover off thinking I would see something , but everything looked ok. The pistons were wet with oil on them. I pulled the lower unit to check the water pump and found that the impeller was burned thru on the bottom plate. Plate was ok after I got the impeller rubber off. The sides of the housing are grooved up a bit. I think the water pump wasn't working. Any thoughts ? where can I get a water pump and housing ? I can't seem to find one online . All the ones shown online have 4 bolt holes mine only has 2 .
