"Hi all ive had this boat for just over two years and the cooling water in my engine is a dirty brown colour I have flushed it out three times in this period and added high quality anti freeze with a corrosion inhibiter but within a short time it goes back to being brown again. The engine has done 1200 hours and I average about 400 a year, does any one know if this is a problem or not, apart from that the engine runs good as new. regards peter."
