    2001 Mercury 150 overheat.

    Hi, i sucked up quite a bit of sand a couple of days ago and my engine started overheating within a few minutes. Since, I have changed my thermostats and water pump, and flushed my engine. At first water could not exit the telltale but I stuck a piece of wire in there to clear it. Now it...

    2001 mercury 150 sluggish acceleration

    Hi all, i have a 2001 mercury 150 saltwater series that has been becoming more and more sluggish when accelerating. When I put it up to full throttle it doesn’t have the punch it did in the beginning of the season. It will start off sluggish and then suddenly it will get all of its power back...

When I shift into forward or reverse my RPMs drop from about 900 to about 600 and my engine seems very unhappy. It shakes a little bit...

    Sudden oil consumption

    Hi, I have a 2001 2-stroke mercury 150 saltwater series motor. To begin the season the boat was going through the "normal" amount of oil, but recently it has been guzzling it down. I would say every hour or two of use I'm adding about a quart of oil. I cant find any leaks anywhere, and the motor...

    Ignition module screws

    does anyone know what screw size and thread is used to fasten the ignition module on a 2001 3.0 mercruiser? The exact screw has been discontinued and i couldn’t find specs to find a comparable one. I dropped one into the hull of the boat and searched for a long time with no luck. Thanks!

    Head Gasket / Milky Oil

    hi, boat is running fine but there is an air leak I can’t pinpoint it. When it runs it is loud. I did a compression test and have 150 in all 4 cylinders (2001 mercruiser 3.0). If I have full compression it isn’t a head gasket (based on what I know, but I don’t know that much), so I was...
