    Pros & Cons of going open loop in salt water?

    It is 100* degrees here in Texas the heat soak is terrible,
    I have been kicking around the open loop idea for a while,
    any suggestions?
    thanks,

    My personal opinion is its a horrible idea for the rec rider, just the thought of all the salt deposits in the block make me cringe. Tho most do flush their skis out after riding, I remember when I took my 30hp honda apart and there was salt in every passage (never flushed that, and I live in brackish water).

    But it will help cooling, and now that they have the inline thermostats its pretty much fool proof. You could do a heat exchanger mod with a 30 plate. If I remember correctly they help eliminate heat from the hull over a stock setup to a point

    I run open loop and love it. But I dont really ride salt water. For our heat down here I am not sold on a heat exchanger, especially if you are reving higher than stock.

    I know plenty of guys that have done it, but it wont be me.

    I have seen quite a few motors that were ran OL in the salt, they were flushed regularly and still weren't very pretty.

    As long as you flush properly and run antifreeze or a good corrosion inhibitor in the engine before you let it sit it should be fine.

    I've been running a 30 heat exchanger setup this summer. Our temps here have been between 98-110 degrees with 90 degree water.
    I have had zero issues with setup and don't notice any fade or cooling issues.
    My HX is plumbed after IC and then to exhaust. I have not had any exhaust cooling issues even on long wot runs.
    I'm dumping some water over board off my mid pipe and water is pretty warm but seems to be adaquate. I like to run as minimum amount of water as possible to my mufler but still enough to keep cool.

    Sorry, got off topic. Lol

    Thats great. I dont really know to many people running it and reving real high. The only one I know of has had problems, but they may not be related to the exchanger.
    I think thats the kind of info I think he is looking for.

    40 plate is WAY to much...
