    Volvo penta aq125a

    After getting the ignition corrected the carburetor needs to be cleaned. Most times there is some gasoline sludge in the bottom of the float bowl. Also the brass plugs and jets need to be removed to get the internal passages cleaned. A good chance the gaskets can be reused but try to get a...

    Mercontrol cables

    You better check on the dimension of a concealed side mount first. There might not be enough room between the inner Gunnal and the inner panel. The 2 parts that wear in the white control box may still be available.

    Mystery Outdrive Gear Oil Leak

    The extension of the lower gear is made of steel. If the lower seal should fail then water will cause the steel to rust and the extension will get pitted which will cause the seal to leak. Try doing what I suggested in post # 4 first. If oil leaks then you now know what to do.

    Mystery Outdrive Gear Oil Leak

    Most likely the shaft seal surface on the lower gear in the upper gear housing is the problem. Refill the drive with it tilted then remove the lower and plug the oil transfer port. Let it set and watch if oil leaks again. If so then look up into the upper and you will see oil dripping from...

    Bogging in relation to distributor

    Have you ever tried just replacing the rotor when it starts to lose power? Rotors will go to ground when hot and the symptom you are describing is how a marine engine acts when that happens. Do you have electronic or breaker point ignition?

    The shift wires at the transom are green for go and blue for back up. The connections are covered with rubber tubes . With the ignition on and the shift in forward or reverse the propeller shoiuld lock in one way and fell springy the other way, this tells that the shift switch is working. There...

    Motor runs but in water dies when throttled

    For a boat that age there is a very good chance that the suction tube in the tank is some of the problem. There is a fine mesh screen inside the tube that has to be removed and left out.

    Motor runs but in water dies when throttled

    I hope the carburetor you purchased is a Marine carburetor for your engine and not an automobile version. When did the problem begin before you started changing parts? The problem may be in the fuel tank suction tube. Have you checked the condition of the fuel hose between the tank and fuel...

    Trim pump not working in down position

    If your friend provides enough weight to get the drive to go down and it does not go down after raising it then the problem is the packing where the ram rods extend. Corrosion can build up between the “O” ring seals and the retainer nut. Sometimes penetrating oil might free up the rams...

    1996 Four Winns Sundowner with 5.0 Cobra engine and drive

    Leave the drive off and connect the hose to the thermostat inlet. Do not worry about bleeding the cooling system. It is not like a closed system.

    1981 120 Mercruiser idles rough when hot

    If you have a volt meter check the voltage at the + side of the coil, you should have 8-9 volts, anything less then the resistor wire is the cause. Try to measure the voltage especially when the engine starts to act up.

    1996 Four Winns Sundowner with 5.0 Cobra engine and drive

    Yes, the screen is inside the tube. Also if you are trying to draw fuel through the anti siphon valve that is mounted on the pickup elbow then, that is why the pump cannot draw the fuel. Just drop the suction hose of the pump in the fuel sender hole.

    Mercruiser 120 starting stumped?

    If there is no hole on top of the head then you will find it at the base of the water jacket inside the crankcase. That area is the thinnest part of those engines.

    1981 120 Mercruiser idles rough when hot

    If the fuel system checks out you should look at the distributor. It only has 1 bushing and the other one is in the block above the oil pump. Also the posts that hold the advance springs and counter weights under the breaker plate tend to loosen up. If the posts in the distributor are tight...

    1996 Four Winns Sundowner with 5.0 Cobra engine and drive

    At this point I suggest pulling the suction tube out of the tank. Inside the tube there is a very fine screen that plugs up often, remove and throw it away.

    Engine mount

    Use your engine lift hooked to the front of the engine. This will make getting the alinement easy by raising and lowering the engine. Back the adjusting nuts away from the engine bracket. Once the alinement is confirmed raise the bottom nut to the underside of the bracket plus 1/2 more of a...
