I am looking at a way to try and prevent as much corosion in my engine as possilbe, bieng it will be moured in salt water. Have got a lot of good comments on a closed water cooling system, but from what I gathered might not be a good idea to install on a used engine.<br /><br />Has anyone seen or used this system??? or is it simply a gimic??? thanks in advance DOug<br />Link<br /><br /> http://www.blueoceantackle.com/bt2000.htm
