I assume you mean closed cooling, ie.cooling with fresh water. Yes it can be done. There are a few aftermarket kits out there that can be installed on that engine. The biggest component is the heat exchanger. Do a little searching on the web and you will find a few kits.

What are the odds of us posting at the same time at 1:30 am.:sifone:
No I meant Closed cooling, like the 525's. One of the main complaints of the 575 compared to the 525 is that they are not closed cooled. That's why I was wondering if you could make a 575 closed cooled, especially since I do all of my boating in Salt water. Is this even something worth looking into?

Some of the benefits that most others have not mentioned about closed cooling: You can run higher engine water temp. which will improve ring seal and piston wear. also improved combustion and fuel efficiency from higher combustion temp. less moisture content in crankcase. and in some cases better idle quality.
I don't think anyone makes a bolt on kit for the 575,you will have to buy a heat exchanger and some brackets and modify as needed,ther is also heat exchangers that can be remotely mounted if you have some extra space in bilge,I am installing a fwc kit on one of my 572-700hp engines as we speak,needed to move the alternator and ps to a imco and modify a few things,will posts some pics,If you are installing on an older engine that has seen a lot of salt some good flushing of block needed or you may clog exchanger,set up right fwc is the way to go in salt water,engine parts way too expensive these days and the salt build up is causing damage if you are using your boat or not,flushing helps but i still see corrision on all the engines i take apart that have been run in salt

If you already have run this in salt water over time, I would question at this time of adding a closed cooling, unless you have this torn down at this time and are rebuilding it. You would have to have the block shot blasted and the heads to remove rust scale.

Here's a nice family of remote mount heat exchangers w/the thermostat integrated into the heat exchanger.....you have full circulation through the engine until the thermostat opens and circulation through the exchanger starts......
Neat system.
I think the prices are good too.
