Re: 70 evinrude
bandit,<br /><br />If you're not sure how old the water pump is,I would replace it.<br /><br />Your engine does not have a telltale for the pump.<br /><br />At idle, you will see some spray exiting out of the top of the exhaust tower (just below lower cowl). At planing speeds, this should be a somewhat steady stream.<br /><br />Can you hold your hand on the top cylinder head, for a few secoonds, while the engine is running annd warm? If so, you are proabably cooling OK.
