I use tap water to dilute in my Audi, doesn't seem to do any harm. I've done 160k so far. I don't see why a marine engine should be any different.

Was not aware either of my Audi money pits had any Aluminium heat exchangers ?

Will a good chunk of the radiators be aluminium?

It depends on where your tap is. By which I mean where in the country, not whether it is in the en-suite or the outside wall. At home in Renfrewshire I will happily use tap water but at my daughter's house in rural Berwickshire it has to be deionised.

It's why the area had a lot of dying industries, and the famous Paisley pattern, British Silk Dying was at the far end of the road I lived on in Balloch, now roughly where the entrance to Lomond Shores is now. United Turkey Red in Jamestown on the banks of the River Leven sadly all those industries are gone now.
