The adapters are installed.
Install the adapters (11) for the tubes for the salt water. This includes the new adapter and the new isolation seal. When the adapters (11) are installed, ensure that the ports from the core assembly are in a centered position in the opening of the housing. Do not force the adapters onto the ports if the ports are not centered in the opening in the housing. This may cause a port failure, and salt water to leak into the engine.
Install the new flange, the insert, and the O-rings on the tubes.
