Re: 1987 Mercury 45 HP
Did you take the spark plugs out and see if it will turn by hand? It can sometimes pull water in the engine and hydraulic lock. Or a badly flooding carb or leaking fuel pump will lock a cylinder.<br />Did the starter make a noise kind of like a weird but not very loud squeal? That noise usually means it's trying to turn an engine that won't turn, or your starter is trying to run on only 3 brushes, or the battery voltage is dropping from a bad battery or a bad cable or connection.<br />First, charge battery and clean connections, check connections at solenoid and starter.<br />Then you may want to try,<br />1 Take the plugs out and see if it turn free by hand.<br />2 Pump primer bulb to check to see if it's flooding or fuel pump leaking into engine through pulse hoses.<br />3 Put plugs in and try to start. Check voltage at battery post and also at starter to see if it's dropping.<br /><br />Be sure to look at plugs to check for water pressence. Those moters rarely pull water back in.
