08 RZ2 Hose adapter starboard side

[Fros0080]

I have a 2008 tige Rz2 that I purchased last fall. In the starboard side of the boat back just off the swim platform in the small compartment between the locker and the swim platform is a hose connection. The plumbing for this connector appears to run down and connect to the same hose that comes off the oil oil cooler for the transmission. Can someone please tell me what this is for? Is this a engine flush hookup so I can run this thing out of water? Thanks

Sounds like it might be part of a shower. Cold water side.

Could be the engine flush kit. Is it a chrome piece and cap?
