I have an ‘01 Sea Ray, 5.0L Merc w/Alpha sterndrive that lives on a mooring buoy in saltwater. For various reasons it’s not practical to flush it with freshwater more than a couple times per season so I’ve been searching for another way to abate corrosion. Wish the Volvo Neutra system worked on Alphas, but working from that same concept, can’t I create the same thing using a bypass and a garden-sprayer type Venturi pump? Basically I would tee into the raw water cooling hose with a ball ****, fit a suitably sized Venturi pipe and rig it to suck Salt Away (or whatever chemical) from a reservoir. I would maybe throw in a garden hose flushout fitting to make winterizing easier, then tee back into the line with another ball ****. It’s a little like the Perko concept only hopefully won’t fail catastrophically. Here’s a crude drawing of what I have in mind.
Would this work? I realize there would be some restriction in the flow of the cooling system inherent to a Venturi pump, but I’m hoping that doesn’t matter much since I’m only running it for 30-45 seconds before shutdown to get the chemical into the cooling system.
Appreciate any thoughts from the wise sailors here.
