I am trying to purchase a water pump repair kit for an Evinrude 40hp,
2-stroke outboard engine (believed to be 1975). My problem is in
identifying the correct type. The engine model number is 405864C,
according to the plate - (serial number B 2852). Unfortunately these
numbers do not correspond to any publicised in the manual(s), neither
can dealers recognise these numbers. Can anyone help to identify the
exact part number I will need.?

Thanks,
