Re: 89 150HP XR4 Overheating at Idle
KCLOST The divider is on the newer gearhousings with the updated water pumps. If you have the Waterpump housing that has the impeller 89984, you will not have the divider.<br /><br />The new waterpump housing is metal...the old one is plastic.<br /><br />You cannot upgrade to the new style if you have the old one.<br /><br />TMD
