Does this engine exhaust a "tattle tail" through the upper drive shaft housing???<br /><br />Some motors have a small stream of water that exits through the upper portion of the motor that signifies water circulating through the engine. <br />does this one?<br /><br />A 100hp motor (72 era) had a temp sender/alarm.<br /><br />But I can tell of no way to ensure that the water pump is working correctly on this old 57.<br /><br />Thanks in advance.<br />Dan
