Hi Peggy.
John said you know every thing there is to know about heads? I have a 1988 Bayliner Cierra 2455, (23 ft cruiser). The head is a Bryden-59128-0000. It has a simple upright, small handle, straight up and down, hand pump flush on it. I am trying to find out if any pump rebuild seal kits are available anywhere? Can you set me onto any good leads? I live in Melbourne, Fla.
