[C320-list] dripping raw water pump

[Myron Welch]

Kirk,

Thanks for the reply.  The leak is from the exposed part of the shaft 
behind the impeller.  I did change the impeller and gasket late July, 
but that didn't change anything.  I have written the repair 
department at Torresen Marine and will let you know their response.
