I have a 2001 Larson with a 4.3 L inboard/outboard. Having overheating issues. Replaced impeller on the front of the motor. Replaced thermostat. REMOVED thermostat. Replaced sensor in case it was not really overheating. I’m out of ideas. Is there another impeller in the outboard lower unit or something? A water pump?Any help is appreciated.

Did you check the raw water inlet fitting on the drive?
