Re: 1974 50 hp evinrude water pump ??
Hi Wayne<br /><br />As far as I remembeer this motor is not equipped with tell tale nozzle. Proper water pump operation is ensured by the water leaving the iddle exhaust relief holes, just below cowling on back of midsection leg. Be aware, this amount is tiny when on muffs, as there is not backpresure, and most water will leave through exhaust. In water there should be plenty. If your motor has a regular tell-tale it is located below cowling on starboard side seen from back. Black dime sized plastic nozzle.
