    Vapor Seperator Tank - 2002 250hp OX66

    I understand that there is at least one filter in the VST that needs to be cleaned from time to time. One, I believe, is at the bottom of the high pressure pump pick-up within the vst. How do I get to it? Do I need to remove the VST from the engine first, or do I simply unscrew those 8 or 9...

    How do I use a test tank?

    Hi, I have a 2002 sx250. I think I may have bad fuel going into her. How would I hook up an remote gas tank to check it out? I know smaller outboards have a clip/plug at the engine that the remote tank plugs into, but I don't see that here. Thanks

    Idle Problem - 77' 1150

    I've posted about this before so this may seem familair to the regulars. The problem I am having is that the engine starts beautifully when cold, and idles great for a while. When I take it out and run it, it doesn't want to idle anymore. The motor will only run in fast idle, and when I put...

    1977 1150 IL - Idle problem

    When I put the boat in the water, I pump the bulb, start the engine (easily), warm it up a second, and drive away. No problem. Engine runs smoothly through the RPM range. Perfectly in fact. I was out for about an hour. Get back to the dock, pull the boat into neutral, engine dies. Won't...

    Squeze Ball - Idle increases 77' 1150

    I've been having trouble with my idle. Recently I discovered that if I squeezed the fuel ball the idle would increase. Naturally, I thought the fuel pump was bad so I rebuilt it last night. I was really proud of myself, but the problem remains. What else could it be? Carb floats? Which one?

    Fuel Pump Kit and Motor Year

    I'm trying to find a fuel pump kit for my 1150 I6. I am having trouble identifying the part I need with the serial number on the motor(4737981). I have looked at the mercury marine web site, but it says it doesn't exist. I believe the motor is a 78, but I'm not certain.

    Idle / shift problem 1978 1150 IL6

    I was having problems at idle. When I would put the motor in gear, it would die. I did a decarb, and turned the idle stop screw 1 and 1/4 turns bringing up the idle speed a little.<br /><br />Put the boat in the water, pumped the ball, and she fired right up. It idled a lot better, and...

    Sea Foam

    I have a 78 1150 IL Merc. In an effort to smoothe out the idle a little, I was told to go buy some SeaFoam fuel/oil treatment to clean up the carbs a little. I did, but I'm not perfectly clear on how to use it. The can is a little vague too.<br /><br />What should I do for a good carb cleaning?

    Idle problem 1150 IL6

    Hi People! I have a 1978 IL6 1150. I finally got all the electrical issues worked out and put the boat (16' Avenger) in the water for the first time yesterday. Wow!! The engine started great and screamed at WOT. It was was way faster than I had imagined, and ran beautifully.<br /><br />The...

    1978 1150

    I just purchased a boat with a 78 merc 1150 on it. The day I looked the boat it started and ran great. "Turn-key" suposedly!<br /><br />Anyway, when I got it home, the trim barely worked and the engine would't turn over. Great! I wiggled all the connections and the trim worked for a minute...
