Kohler GM90436 OEM Seawater Flow Switch

If you have one of the above models shipped between March 2008 and Sept 2013 and do not have the flow switch installed, do not use the generator until SB-737 has been done.

This may be covered by Kohler, but your local Kohler dealer will need to supply the part and do the install. 

If you would like to do the install, order GM90489 - Kohler will not refund you if you decide to perform the service bulletin yourself.
