    1990 Dual Force 120s one side showing 16.7v at speed with dual batteries

    That is correct the charging system is 7 amps AND REGULATED! This means the original rectifier comes with a built in voltage regulator. Note voltage regulator not current regulator. However, since the stator is an after market, it could mean the original rectifier specs is not sufficient...

    So it would seem the drawing is inaccurate. I looked on other schematic for 85HP with Prestolite Ignition system, has both blue and yellow wires connected for each CD Unit. Which is the same as you've shown in the video. So the only next step now is to wait for the replacement CD unit and...

    I'm assuming when you did the switch back, you also did the same with the trigger wires, orange and green trigger to Or and Grn on CDI wires. Double check the wiring again against the diagram. And if everything is OK, it could mean the CDI is bad and needs replacement. Note the schematic...

    If the motor is running as you previously mentioned, then the re-wiring must be correct. Otherwise, it would be backfiring or not running at all if re-wiring is wrong. Take note though, the most critical wires in here are the trigger wires. IT CANNOT BE SWITCHED AROUND AS IT IS ALL TIMED TO EACH...

    This is all in the hopes those CD Modules have not been switched before. Anyways, fixing the crimped wires might have also been the initial problem by the previous owner and just overlooked the broken wires. Fingers crossed.

    If you have not done the full swap out yet, check for continuity on that wire using safety pins or even thumb tacks to pierce through the insulation. And if there's no continuity, just use a soldering iron (cutting and stripping both ends) to solder it together, one layer of electrical tape and...

    When adjusting the cam's scribed line with the slot on the eccentric screw, three things should be "mechanically zero". Meaning basically no mechanical force is being exerted by the carb's linkage. -First and foremost, the idle screw setting should be screwed OUT and just barely touching the...

    If the idle screw screws all the way in and the idle remains low, it's an indication the link rod with plastic clevis on both ends that connects the throttle cam to the carbs' tie bar through the eccentric screw roller is improperly set or adjusted. The indication is that it is too short. To...

    Some boaters put water-fuel separators between the fuel tank and the fuel pump. I do not for I have not experienced any water in the fuel problem. Although, my boat is always parked on the side driveway and not year round in the water like others. If you're NOT experiencing water in the fuel...

    The fuel air mixture screw is easily identifiable with a spring in its body. Usually, it sits on top of each carb or sometimes right there on the very front of the carb. When situated on the front, it's not easily visible as it is recessed. To see it, you will need to remove the air covers for...

    1997 force mercury 40 hp- starting sequence?

    The start sequence you are now doing is almost perfect except for one or two steps. When priming with the priming bulb, you need to continue to depress until it is firm. NOT HARD BUT FIRM. An indication the fuel pump is primed and the carbs floats are all up and putting in a resistance to more...

    The initial setting of 1 1/4 turn out is more like a good engineering practice when recommending settings on the fuel air mixture. Technically, the initial setting (take note initial setting is not the same as recommended setting) per manufacturer's document is 1 turn out from lightly seated...

    85 force lower unit drain plug

    Basically, you can only replace the plug wire boot but not the entire plug wire as it is permanently connected to the coil packs. When replacing the boot, make sure you do not cut off the wire too short. Instead, open the old boot with a sharp knife, de-crimp the existing connector terminal and...

    No it's not possible for a 3 cylinder motor to run on just one cylinder, even at no load. If the motor is firing on all cylinders, pulling one plug wire will definitely give you a change in rpm corresponding with change in engine noise or tone. Again, you will need to familiarize yourself on how...

    With nr 3 wire plug disconnected and engine shutting down, tells me there is a misfire and obviously it is not on nr. 3. The reason it shuts down when you took off wire plug 3 because that particular cylinder is actually working. So you can still do the same with nr 1 and 2 but have to do it...

    Need to specify this location. Normally, for troubleshooting purposes the fram fuel filter (see thru) should be after the fuel pump and before the carbs. Also, there is a built in fuel filter on top of the fuel pump and can be easily removed with a flat tip screw driver. This is nothing but a...

    1989 Force 125 hp Over heat alarm when put in gear

    "I shift into gear and the waters stops coming out of the tell tail above the T-stat." The water spray from the tell tale stops is because a load on the drive shaft slows it down a little but THAT IS TOTALLY NORMAL. Now what a little slow in drive shaft rpm could that have affect on the...

    1989 Force 125 hp Over heat alarm when put in gear

    It's on the t-stat cover but not really sure if it is before or after the t-stat. But a slow flow on the tell tale is an indication that not enough cooling water goes to the cylinder water jackets, if the tell tale is before the t-stat. But if it's after, it means the t-stat is either not...

    1989 Force 125 hp Over heat alarm when put in gear

    With slow spray on the tell tale by the t-stat, it could be the t-stat is blocked or not working anymore. Try removing the t-stat and test if the alarm goes off again (without t-stat). Then test the sensor itself, as mentioned. If sensor tested ok, it could be the key on the impeller was not...
