"I RECENTLY PUT A MODEL 470 IN MY BOAT, AND I GOT IT FIRED UP WITH THE EAR MUFFS ON THE LOWER UNIT, AND THE HEAT EXCHANGER IS GETTING REALLY HOT. MY OLD ONE USED TO BE COOL TO THE TOUCH. I HAVE A LOT OF WATER COMING OUT OF THE PROP HOLE BUT HARDLY ANY WATER COMING OUT OF THE EXHAUST PORTS UP ON THE TRANSOM. I TOOK THE HOSE OFF THE FRONT OF THE HEAT EXCHANGER AND THERE SEEMS TO BE GOOD SEA WATER PRESSURE. THE LITTLE BIT OF WATER COMING OUT OF THE EXHAUST PORTS IS PIPING HOT! THIS SHOULD BE LUKE WARM WATER. WHY IS ALL THE WATER COMING OUT OF THE PROP EXHAUST AND NOT OUT OF THE EXHAUST PORTS? AND WHY IS THE HEAT EXCHANGER GETTING SO HOT?"
