Re: Heat exchanger
Check out boatfix dot com. They have great prices on cool-craft systems. I'm going to be adding FWC systems to my 454's this spring. <br /><br />Has your boat bee run in salt water much? If it has you probrably don't want to do the conversion. If it's been in fresh water then you'll need to take the thermostat housing off and look inside the block to check the conditionl. If you have flaking rusted metal then you can not convert to a closed loop system. If it's just rusty looking, but not flaking then the block can be acid flushed and amonia rinsed, then you can install the closed loop system.<br /><br />Jeremy
