    Your zincs won't do much if anything in fresh water

    I read that as one of his points, flush and fill with FW and the zincs last longer. That must save at least $20 a year.

    I've noticed few bother posting on this forum but me. It's not hard to see why. I've been on various forums over the years and this is one has the most dickish attitude from some of its posters I've ever seen.

    Enjoy your time together.

    Interesting. Within two months of membership you suddenly know all about us and boats. With some help from another site, you come back on an inquiring post that you started and now blast some most helpful members with your new found expertise.
    A friendly thought;
    It will take you a life time to acquire a scratch of experience some of these members are trying to share with you.

    Enjoy your time,, maybe better,, away.

    If you came for answers you got them, if you don't like the answers that is not indicative of a "dickish attitude."

    If you want support for an idea or project that has few if any upsides and several downsides then go to one of the toyboat sites where they thrive on stuff like fuel polishing systems, buttock lines, anchor types, how to connect and charge batteries, and what their boats are called.

    Marmot,

    It is possible to answer someone's questions without making some snarky comment like "save $20 a year." Give it a try sometime, I'm confident you can do it! I'm sure you know a lot about boats unfortunately it seems you don't know how to share that information without "dickishness". Maybe you're having a bad day although I've seen this pattern in other posts of yours.

    Thanks to all of you that wanted to help me out with my new boat questions, I do appreciate it. I have learned a few things here.

    Jrms80-
    Your solution is not solving any real problem; it is adding more complexity to a system which needs none and it's introducing items which cost money and could fail. The main engines pick up raw water from a seacock- are you putting a "Y" or a "T" in the pick up hose plus a valve which is then adapted down to the size of the fresh water hose? There's about another dozen questions but no need to ask or answer them- your idea causes more issues than it solves. As a professional sportfish captain for 20 plus years I can tell you no one else with any length of experience does what you are suggesting, and for good reason. Your idea here is not worth the time if the boat sees 100 hours a year or 600.
    Plenty folks will show up on the dock or here in a forum and tell people what is good and wise; however they have yet to gain the experience to know what is good and wise. Those folks ideas are shot down and predictably they tend to get upset- as you are. Get over it. Yes some ideas merit consideration and also predictably those are debated- your idea is not one of those. Every boat has a nearly unlimited number of items which could be cleaned, made shiny, maintained, fixed or paid attention to: go find those on your boat instead. Ask about other things and we'll answer your questions without prejudice.

    I will try and be nice ... first off, I was responding to K1W1, not you. Secondly, saving $20 a year is $100 every 5 years. As Mr. Herbert said once, "A penny spar'd is twice got." Why that should offend you is not worth discussion here.

    Just because you don't like the information you asked for does not mean those who supplied it are being "dickish." Take Bamboo's advice to heart and you might learn something. If you are here to insult people rather than benefit from knowledge and experience freely offered then good luck with your future boating activities.

    What you want to do is a fix in search of a problem. In order for saltwater to corrode things you need oxygen present (air), without that component the saltwater doesn't corrode metals. Having freshwater sitting in there, really isn't going to change anything. Same for the engine zincs.

    FWIW I know someone who did it. But he's not your average boater.

    Kept his sportfisher in a remote location with a fair amount of downtime between visits. Before he went home he would run freshwater - with motor running - into the saltwater side of the mains and generator.

    It required two hoses from the dock to get enough water flow for a Cummins 6BTA. He closed the thru-hull and had a contraption that connected the two dock hoses for supply to the raw water pump.

    He didn't like leaving the heat exchangers, after coolers, and oil coolers full of salt water - which is beside the fact he serviced them every couple years anyway.

    My thought would be to do it if it gives you piece of mind notwithstanding it may or may not work or create more problems. Only God or fools can be sure of results.

    For what it's worth. I had also heard of installing this system as a few people have done this. At first glance, it seemed like a great idea but after thinking it through and reading some of the comments here, I agree that it's not enough of a gain to warrant the expense and complication. Great for an outboard etc. but for the very minor potential gain... No real shortcuts for just good old fashioned servicing.
