I've been chasing this down on the net, and talked to a few different people at mastercraft. getting a lot of different answers. some say a raw water hose re route kit, some say new thermostat housing up date, and last but not least, could be as simple as moving the temperature sensor because its reading air. has anyone had this problem on their ly6? if so any help would be awesome


thanks Robby
How old are the raw water impellers?

I made the assumption it is open cooling. Is it open or closed cooling?
