Peter T and Philip T both vouch for this flushing system. Peter’s words: “Reverso system plumbed in to the motors. Plug/screw in hose, push button, walk away!” Philip’s: “Plug in the water, flip a few valves and push a button…done! Worth the money for sure.!”

Philip shared “We bought the ‘four engine’ reverso. The third and fourth outlets flush the Fischer Panda then the SeaKeeper and three a/c units, resulting in no saltwater aboard. We have two full size DI bottles on the dock which run the entire boat while ‘slipped’”.
Philip also said “… anyone interested, try Citimarine in FL. The four port unit retails for $1319, and I paid $880 (there) just for comparison’s sake. Also, if Mercury had put the flushing port under the cowl top lid, we probably wouldn’t be having this discussion.”
Here is where Peter put his quick connect plate. HIs comment: “It’s next to the transom shower and impedes the metal gate until you move the bench! This is viewed from the top.”


Philip replied later “Peter, if that bugs you enough, Aquor Water Systems makes a flush mount outlet with a variety of quarter-turn hose connections. Looks like an easy conversion from your current deal. FWIW.”
