Diaphragm for the selfbailer with the sliding system. The diaphragm is made of thin rubber and you can easily replace it yourself.
To do this, you must completely loosen the round knob of the self bailer system on the outside of the transom plate (engine plate). The diaphragm is located in this round knob, after which you can replace it.
We have enclosed a few pictures of the diaphragm and the round knob. (With the grey selfbailer kits, this round knob is light grey.)
The complete self-bailer kit in black (Z60502) and grey (Z61083) can also be ordered from us, see the overview of related products.
