I just picked up a boat with a 2003 225 Ficht Evinrude on it. The boat has a water pressure gauge on the panel, but whoever rigged the motor did not connect the hose at the motor. It is just lying inside the motor cover. Can anyone tell me where the fitting for the hose normally screws into on this engine. I see a boss on the exhaust cover with an allen screw in the hole. Is this the right place?
