Background: Boat new to me last year, still working out all the kinks and understanding all the systems. PO owned 2 years and its fair to say never took engines over a slow idle for various reasons, primary being loose throttle cable connection at the helm that simply wouldn't grab the butterfly's before the lever was max'ed out! Amongst other things... Anyway.. Pushing the engines harder now and its time to validate the cooling system.
First indication I needed to understand everything better was Port engine had the input to Sherwood pump on the the opposite as the Star. Second indication is the service manual only speaks of a single impeller RWC System.... Hence confusion.

To be objective, what I do not understand most is that the tranny oil cooler being fed off what i think is the "input" side of the dual pump... I guess my lack of pictures of the tranny oil cooler plumbing is racking my brain, and hopefully i can get to her this weekend. Referencing this post, I continue to believe all makes sense on the 'top' of the engine.

and the second image of the RW system... I get confused on how water is getting to the OC!!
(To be continued... im going to continue to edit and add to this post, saving drafts looses the pictures!)
