    Motor tilt problems..

    I have a mercury outboard, and here lately I have been noticing the tilt is not staying up. What I mean is, I can tilt the motor up, then come back out a little later and it is all the way down. I've never messed with the tilt on these, anybody know what might be going on? Thanks alot.

    Mercury makes popping sound..

    I have a 1990 mercury 90 horse 3 cylinder. I had taken the carbs off of this to clean them, I got everything back on, and my problem is, the motor can be setting there idling, and then all of a sudden you will hear a pop type of sound, and on the tach it loses about 100 or 200 rpm then it goes...

    Fuel line..

    I was wondering if it is alright to run the automotive fuel line on the mercury outboards? Nobody around here seems to sell the outboard motor specific fuel line. Just curious what you guys run. Thanks

    Mercury carburetor question..

    I have a 1990 mercury 90 horse 3 cylinder. And I am looking at a set of carbs for it. My carbs had the marking of 3301-9012 on them. I am looking at a set of carbs off of a late 80's 75 horse mariner with the same exact number on them. Will these work alright? I believe I was reading that quite...

    Plugging up livewell..

    This boat of mine had a livewell in it, and I am taking it out for more room. I was wondering how would be the best way to plug up the holes in the back of the boat. It has the water in hole, water out hole, and the respirator pipe that sticks out the back of the boat. I'd like to keep them...

    Mercury surges..

    I have a 1990 mercury 90 horse 2 stroke outboard. My problem I'm having is, the motor surges when I have it on the muffd. What it does is, it will be idling at around 1100 rpms, and then all of a sudden it might surge up to 1300 or sometimes I can see the rpm drop down to around 1000 or so. Also...

    Spark plug question.

    I have a 1990 mercury 90 horse 2 stroke. I've pulled the plugs off of this a few times, and they have what appears to be black oil on them pretty heavy. Is this normal for a 2 stroke, or am I possibly running it too rich? Thanks

    Fuel questions..

    I have a few fuel related questions. I have a 1990 mercury 90 horse outboard. 1. whenever I get done running the motor, and let it set say overnight, I should have fuel still left in the fuel filter shouldn't I? Reason I ask is, the fuel keeps running out of the filter, to where it's almost...

    Mercury oil pump..

    I have a 1990 mercury 90 horse, and it has the oil injection on it. I had to take the oil pump off, now I am ready to bolt it back on. My question is, the knob type deal that turns in and out on the back of these that fits into the crankcase, does that need to be screwed in or out, or do I...

    fuel problems.

    Hi guys, I have a 1990 90 horse mercury 2 storke. I have been having some fuel problems for awhile now, and trying to figure it out. What the deal is, is when I give the motor some throttle on the muffs, the carbs make a sucking sound like there not getting fuel, and then it will just die after...

    Mercury Oil Pump..

    I have a 1990 mercury 90 horse with the oil injection. I had taken the oil tank and lines off, and put everything back on. When I turn the motor over to try to get oil to come out of the outlet hose into the fuel pump, I get nothing. Does this sound like a weak oil pump? I went ahead and took...

    Oil Pump question..

    I have a 1990 mercury 2 stroke 90 horse, with the oil injection on it. I had to take the oil tank off, and had to undo the inlet and outlet oil hose. I got the hoses back on, and I bled the inlet hose till no air bubbles, but my question is, what do I need to do to get the oil up to the outlet...

    Inlet needle valve question..

    I took the inlet needle valves out of my carb, and 2 of them have a black ring around them about halfway up or so, the grooves on the bottom of them look ok, is that normal, or is that wear on them that needs to be replaced? Been having some what seems to be carb problems so was just curious...

    Backfire upon startup..

    I have a 1990 mercury 90 horse, whenever I go to start it when it's cold, it will backfire out the exhaust. But whenever it finally starts and gets to running, it does not do that when I start it again. Any ideas what could be causing something like this? It seems I have to keep the choke pushed...

    Have to keep pumping primer bulb..

    My outboard has been running bad for awhile and I could not figure out the problem. It seems like a fuel starvation problem, whenever I would finally get the motor running, if you gave it just the slightest bit of a throttle blip, it would die, or have a sucking sound to it and kind of stumble...
