I have a 2000 175XR2 powerhead attached to a merc jetdrive. The head temperature guage is indicating 155-165 degrees F which seems a bit warm. Currently, the cooling water hose comming off the heads vents to the pee hole fitting and the cooling water hose at the top of the block terminates to the exhaust on the adapter plate. Is there a plumbing configuration that would help me lower the head temperature. Would venting the head cooling hose to the exhaust and venting the block cooling hose to the pee hole fitting lower the head temperature?
