Default Merc 7.4 rising temperature

Just to follow up, I replaced the circulating pump because it was
going anyways and the problem was still there. It wound up being crud
blocked up on the backend of my oil cooler on the intake side so not
enough water was getting in the system. I pulled the hose, cleaned it
out and its been perfect since. Thanks all..
