    '87 Force 125HP ignition problem

    How did you test stator voltage output? With DVA adapter? Got a pic of the DVA adapter? Was the VOM meter on DC voltage reading with the DVA connected? Have you tested the DVA making sure it actually works?

    '87 Force 125HP ignition problem

    Really very surprising with so many bad stators back to back. And this is so baffling especially without any signs of overheating or rusting or broken wires. But you are correct with your readings.

    '87 Force 125HP ignition problem

    Just to make sure we are actually on the same page, can you post a pic or video showing the VOM reading (ohms reading) and which pair of wires you are taking the readings from. This reading is on an uninstalled or dismounted stator. Although stator do break, they seldom do. And if they do most...

    '87 Force 125HP ignition problem

    Was there any burn or overheating marks on the old stator that had zero output readings? Anyways, since you already moved on I guess you can use this as a training aid or even a spare if repaired.

    '87 Force 125HP ignition problem

    Well @jerryjerry05 once again, you were right; a "tested good" stator can be bad :) @Jiggz one thing stays a mystery, how when I disconnected the kill wires from both packs #1 & #2 started firing and that I tested it with VDA attached I got no reading?? This is why I recommended taking stator...

    '87 Force 125HP ignition problem

    Testing the voltage is across each pair of the blue and yellow wires. Using a DVA with the VOM set to test for DC voltage. You can test connected or disconnected but disconnected (both pairs) is the preferred method just to make sure no other interference. Just make sure none of the wires is...

    '87 Force 125HP ignition problem

    It's possible a separate winding from the stator is bad. To verify, with the kill wires disconnected from the terminal board inside the cowling, switch the blue and yellow wires (from the terminal board) and then check for sparks again. If the no spark switch to 1 & 2 (which previously have the...

    Trim motor

    Power is supplied to both green and blue wires to power the motor. The motor reverses based on which wire gets the positive and negative from the battery through two independent relays. The two relays does the switching depending on the Up and Down T&T switch. No electrical connection to ground...

    Water flow direction in a 50 hp force

    I presume since the tell tale is on the t-stat housing that water is going into the t-stat instead of coming from the t-stat. You can check this by watching the tell tale water flow as soon as you start the motor and water starts flowing from the tell tale even before the motor reaching...

    How to set up an induction tachometer

    That is correct. You just have to bear that in mind and divide the rpm indicated by two. I have the same tach you have and tried everything until I came across a page explaining the dual spark system on most 2 cycle engines.

    How to set up an induction tachometer

    It looks like it is set correctly. The type of tach you have actually relies on the spark plug getting energized. And with this Force motors, they have what is called dual spark meaning you get two sparks per revolution in each cylinder. So the tach reads twice the actual rpm. In a non-dual...

    Locate year of engine? Force 50 (and best place to get a service manual (cheap)

    Try cleaning the battery cables and most especially the ground connection to the engine block. DO NOT JUST CLEAN THEM INSTALLED. REMOVE AND CLEAN TO A SHINE AND THEN RECONNECT. If this does not solve the weak cranking, then disassemble starter and clean the commutator and check brushes for...

    The fall

    Sorry to hear that. Hopefully, you'll be feeling better soon.

    Reduce kick when putting in gear

    Congrats but beware, idle mixture screw should NOT be set less than 1 turn out from lightly seated. This can cause a lean idle mixture that can cause damage to the piston and cylinders.

    Bad trigger? Can’t adjust timing

    Just to make sure we are on the same page. Here's a pic of the timing screw just below the flywheel. Note however, this unit has a broken part so it'll look different from what you have orientation wise.

    1996 Force Mercury 120hp starts then dies HELP

    Before going any further. Disconnect the white wire from the electrical terminal located on the port side of the engine. This is the shut down wire for the two CD boxes. Check for sparks again. But make sure you are ready to shut down the motor if it starts by touching the same white wire to the...

    Bad trigger? Can’t adjust timing

    The biggest challenge of replacing the trigger is the flywheel removal. If you get lucky it could just be an easy pull out using a bearing puller. But many have cracked or even destroyed the flywheel without success using a three prong bearing puller that is mounted on the rim of the flywheel...

    1996 Force Mercury 120hp starts then dies HELP

    I'm a little confused. Are you saying the wiring diagram I posted (#13) is not a Prestolite ignition system? Can you please elaborate?

    1996 Force Mercury 120hp starts then dies HELP

    Well even better, 125's of all years have basically the same wiring diagram using the Prestolite ignition system. Later models just like 89 and later may have a different wire colors but the wiring is still basically the same. Here's a 125 wiring diagram.

    Force 120hp won't start

    Here's a drawing for you. But it all starts with the water tube from the impeller, to the exhaust manifold and then to the top of the power head where the t-stat is located. The exhaust manifold also has a small opening (relief valve) that allows small amount of cooling water to exit while...
