Group;<br /> I have single Mercruiser 260 Alpha-one that is runnig a warmer than normal after I added STP Dry Gas.The engine temp increases during low rpm but returns to normal when engine/ boatspeed increases. Any thought would be helpfull.
i just added same to 16 gallons and nothing has changed. coincidently, after adding, your water pump starts showing classic early signs of failure is my WAG.
