    How do I test a starter solenoid that's attached to a starter? (20' Shamrock 2001)

    Take a look at the main starter solenoid, there will be a #10 yellow/red wire, get a test light and check if the light works when the key is turned to start. If it does not light then trace the wire to the smaller solenoid and test it the same way.

    My boat sank, part II

    Mike I can feel your pain, at least the boat is still upright and you should be able to re float it. I am sure you will be able to bet it back running again. The local images around here show a lot of boats that are either sideways on the bottom or just on the bottom.

    5.0GL Possible Carb issue

    It could be fuel starvation as the symptom you are describing. Start checking and changing the fuel filters. The only other thing to check is that the throttle blades could go past wide open and start to close. Pretty rare but it needs to be checked. Is the flame arrestor clean and not plugged...

    Mercruiser 3.0 Oil Pan

    Take a close look at the timing cover, it has areas that were never painted and this would be a good time to replace it also.

    Stern drive woes

    You do not have to worry about reinstalling the shift shaft. There is no way the “C” shaped lever can come dislodged. The entire propeller shaft has to be removed before before the lever can be removed.

    Stern drive woes

    If you are worried about drill chips in the lower then try this. Below the bushing is a flat washer with a hair pin clip or another type of retainer. With 2 pair of vice grips biting the shift shaft splines pry up and the clip will either break or open enough to pull the shaft out then with a...

    Mercruiser 888 no go over 3000rpm

    If all of the above checks out then I vote for the fuel system as the cause. Considering the age of the boat and fuel system‘s age take the 6 gallon outboard tank challenge. Connect it to the fuel filter inlet and give it a run.

    Mercruiser 165 distributor breaker plate

    While the breaker plate is removed make sure that the fly weights and springs are in good condition and the rotor shaft does not have excessive play causing the points to not hold a steady dwell angle.

    Urgent help - nearly broke down at sea. Fuel Problem.

    Good possibility that the screen in the suction tube is where the problem is. Hopefully you will be able to unscrew the fitting from the tank, the tube screws into the 90* fitting so that you push the screen out with a suitable tool.

    Inconsistent Sparks

    Get a jumper wire and connect the + side of the coil to a 12 volt source and check the spark while spinning the engine. You may have a problem with the starter boost solenoid By-pass circuit which delivers 12 volts in cranking mode only. Does the rotor shaft have enough movement to make the...

    1977 OMC Stringer running hot or ??

    Start with the clear hose idea, the only problem about running in a tub is picking up bubbles. You want clear going in and also going out to the manifolds which will indicate a head gasket leak. You should at least try another water test.

    No engine alarms. Can’t find anything in service manual.

    It will also help if you added a water pressure gauge which will show a low reading before the engine overheats.

    Alpha One power steering - how to remove cable?

    If heat and penetrating oil does not work then try this. To make it easier to handle unscrew bolt #19 and pull off the tapered bolt with #17 that the Doc sent. Then pull the cable jacket as far out as possible then if you have an abrasive saw blade cut the inner cable next to the outer...

    IAC whistle ??? Merc 7.4L MPI

    There is a small piece of foam rubber about 1/2” square that fits in the IAC that muffles the sound. Over time it breaks down. I had that problem with my Donzi and that cured the noise.

    Alignment help!

    If the transom checks out to be solid then since I do not have eyes on your boat I have another question. Does your boat trailer have keel rollers? If so it is possible that the hull has settled which will raise the front mount taking in consideration the age of the hull. Mad props and Scott06...

    U-joint seized into gimbal bearing

    It is possible to cut the shaft and it may be possible that the shaft is bound up in the drive coupling. I have had to use a cutting torch while my assistant kept a garden hose going at the same time. If you grab the joint with pliers is it possible to feel some slack in the splines. If so...
