I believe it might be time to service parts of my Jabsco head. It appears there are two different service kits, pre-1997 and later. How can I tell if I have a pre- or post 1997 Jabsco head?
In case anybody else wanted to know. Jabsco ITT says that:
If the handle on your pump is:
Black then you have a 29090-0000 (pre 1997)
Grey then you have a 29090-2000 (1998-2007)
Dark blue then you have a 29090-3000 (post 2008)
