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.



those number don't jive with the factory's model year guide. According to
the Parts and Accessories Catalog that dealers receive every year, there are
about 15 listings for various models and years of a 40hp, and about 4
different types of impellers.

Remove the water pump from the motor and take it to a "savvy" dealer and
have them match it up. Parts people may not recognize the what the impeller
came from, but a long time OMC outboard mechanic may be able to help
identify it.

Good luck
