I'm selling a spare raw water pump for my Northern Lights Genset.  I purchased it several years ago from Hatton Marine in Seattle where it was taken from a new genset and offered to me at a good price.    It includes the O-ring and the drive gear PN 340460141, so it is a complete new bolt-on unit for the M843NW3 and others below.  It has never been used. Please check your parts catalog for compatibility, especially the drive gear, which is removable.  I will pull the gear for the purchaser if they desire.  Searches show that this 25-12057 Jabsco pump is a replacement for the following Northern Lights/Lugger units: M843JK, M843NK, M843NW2, M843NW3, NL843JK, NL843NK, NL843NW2, NL843NW3 M16C, M20CL, M20CR, M20CR2, M20CRW2 M753K, M753W, M753W2, NL753K, NL753W, NL753W2 M773LW2, M773LW3, NL773LW3 L844D, M844K, M844LK, M844K2, M844LK2, M844LW2, M844W2, NL844K, NL844LK, NL844K2, NL844LK2, NL844LW2, NL844W2 Web searches will show this Jabsco pump without the gear for $350 to over $600.  Asking $249. including shipping domestically via USPS. Please email me if you would like photos. Thanks, Rich Losch OCEAN LIBERTY KKY52-01 Ft Pierce, FL Rich2@reagan.com
