    1995 Force 120 will no longer idle

    My stator is the 6-wire black one, with high and low rpm circuits. The two yellow wires for the battery charging circuit, should not be affecting the spark issue, even if out of spec, unless there's a short somewhere. I rechecked the resistance and it is 4 ohms. (0.4 on the 10X scale) I have...

    1995 Force 120 will no longer idle

    Flywheel is off, with a bit of subtle persuasion. The magnets are all in place, and there's no visible damage to the stator. The stator is labelled: 398-8778A24. I will double-check the resistance readings and if they are still testing out of spec I will buy a stator. Need to decide which one...

    1995 Force 120 will no longer idle

    I'm pulling the flywheel to check the stator and the flywheel magnets. Two of the stator circuits are out of spec. Blue-to blue/white should be 3250-3650 and it is 2200 Ohms. Red-to red/white is 100 ohms. (spec is 75-90) I don't know if that amount of out-of-spec is the problem...

    1995 Force 120 will no longer idle

    My stator does not have green/white and white/green wires. It has 2 yellow to the rectifier (which is new and working) red, red/white, blue, and blue/white. I'll be taking all measurements shortly.

    1995 Force 120 will no longer idle

    I tested the primer by listening for the click when I press the key in to verify the solenoid is working. Then I disconnected the feed tubing from the primer valves to the carb, squeezed the bulb until firm and observed that no gas comes out of the valve. Then I push down on the plunger...

    1995 Force 120 will no longer idle

    Another sunny day half wasted. :( Coils all meet spec. The primer solenoid works as intended. Still no spark. Trigger tests to spec. The stator is somewhat out of spec. Resistance measures 2000 where it should be 3600 or so. I don't have a DVA tester to measure output voltage. I may...

    Another sunny day half wasted. :( Coils all meet spec. The primer solenoid works as intended. Still no spark. Trigger tests to spec. The stator is somewhat out of spec. Blue wire to blue/white measures 2200 where it should be 3250-3650. Hard to know if that is enough to cause no...

    1995 Force 120 will no longer idle

    Thanks for the suggestions, all. I wasted another sunny day on this motor. Now it will barely run at all, and only briefly, and at about half throttle or above. I checked all the wiring on the switch box, found that the insulation had melted off the red wire, and bare wire was contacting the...

    1995 Force 120 will no longer idle

    I've been thinking about it more, and researching, and today I'm going to work on it with the assumption that the carbs are not the problem. I'll be checking the ignition circuit and wiring, starting with checking for spark when starting with the control lever in the neutral position. I've had...

    1995 Force 120 will no longer idle

    My no-idle problem is back. I've used the boat half a dozen times recently, with more or less no problems. On a two day outing, near the end of the second day, the boat was idling, then slowly decreased in RPM then died. Now it will not idle at all. When I set the control to open the throttle...

    1995 Force 120 will no longer idle

    One more question. Should the over-heating buzzer sound sometime during the starting sequence? It doesn't now, though the buzzer sounds when I put 12 volts to it, and also buzzes if i jumper the connection at the motor sensor. (as I recall) A lot of motors do that, but mine doesn't. I 've...

    1995 Force 120 will no longer idle

    Great success today. Reset the timing to 29-29 deg BTDC, it was adnaced about 4 degrees too much. Reset the throttle linkage, it was only opening about 3/4 before, and set the idle with the stop bolt thing. Boat ran GREAT at the lake, amazing power. I now need to order a new prop with more...

    1995 Force 120 will no longer idle

    Update: News reeds are installed. Kind of an easy job, my first time doing it. 9 of the 24 old reeds were chipped or cracked. One was half gone. Reattached the carbs, and she fired right up. No gas leaks. Idles fine at 900-1000 on the muffs, but when I go lower it idles rough or dies...

    1995 Force 120 will no longer idle

    I saw that carbon set on ebay, but something is wrong as the picture shows sets of 5, and my motor has sets of 4. I couldn't find any stainless ones, only full valve block assemblies. I ordered a set of fiber ones from CCMS, which look correct in the photos (Link below). How might I find the...

    1995 Force 120 will no longer idle

    Well I pulled the reed valve blocks and I see that one valve is missing, many are cracked or chipped, and they all hang open a bit leaving an air gap. I'm surprised it ran at all like that. I imagine I was getting little compression in the top two cylinders at idle. I think I'll replace them...

    1995 Force 120 will no longer idle

    Last year I had great use of my Trophy 1802 with the 1995 Force 120. I had replaced plugs, fuel pump, filter, fuel line, I run from an external tank with non-ethanol fuel. I was able to adjust the idle perfectly last year, properly fitting the idle screws at 1-1/4 turns. and adjusting the idle...

    Optimal prop for a 2004 Trophy 1802 WA with a 125 HP Mercury outboard?

    An old thread, but FYI I have an 1802 with a Force/Merc 120 and I run a stainless prop 3-blade, 13.5 diameter, 17 pitch. I hit max RPM at about 35 MPH. I had an aluminum prop of the same specs before and it went 37 mph. I think that neither of these is right, and I should top out at about 40...

    1995 Force 120 no water pumping through powerhead

    Following up again with more updates. This season my Force engine wouldn't idle. I found that the idle screw of the top carb was way out of adjustment. Did the usual screw it in, then out 1 1/2 turns (I think) at it fixed it. I was still having slow starting. motor turned over slowly, and...

    Rectifier-regulator 4 wire, can I use a 5 or 6 wire???

    Thank you SO much for posting this. I've spend an hour trying to research and figure this out, 5, 6 wire, etc. I just ordered one of the above. Good on ya!

    1995 Force 120 no water pumping through powerhead

    Just though I would check in with some update on this motor. We are old friends now. Every time out something has gone wrong and the motor has shut down. But I have always had my tool box and able to get it running again and home. Here's a list of what went wrong, and how I fixed it. 1) at...
