I have a 302 Volvo Penta with a external raw water pump and a sx outdrive. Just put a new Volvo Penta thermastat in it with a new impeller in the pump and a new temp switch. When I am above 3800 rmp the temp will increase until I lower the rpm to under 3600. I have new risers and wonder if the lower unit is sucking air or I have a bad thermastat. Need help on this matter please.
