Hi guys,<br />I have a outboard merc 800 4 cylinder ID#3190412, when Its idling there is no water coming from the Pee hole, but when i throttle it, It comes out at a steady stream. pee hole and uplift tube are clear, I have replaced the Impeller (which by the way fits really tight, I actually needed to bend the fins to fit back into the housing)<br />A/Does it matter which way the fins are bent, ie Cockwise or anti clockwise?<br />B/does this merc have a thermostat, and is this easy to install?<br />C/What year is this engine? <br />Any help would be appreciated.
