    Force 120hp won't start

    Looks like this is a power head to a L-drive. You can see back fire through exhaust manifold tube that are for the L-drive power head units. Do as The Force Power suggest, do the link and sync.

    Coil Testing.

    To test an ignition coil you need a spark tester with a adjustable gap. The coil should jumpa a spark for 3/8 in or more in atmosphere. But there can be other issues that cause no spark if you check with the coil connected to the engine. To be really sure you have to test with a coil tester at...

    Chrysler 55 one cylinder occasionally fires

    You can make that gasket 47-F286555 for the lower split of the gear case by your self. Get some gasket paper and cut it out . When assembling it coat the gasket with a thin amount of some liquid gasket such as "Permatex Avaition form a gasket" or equal. Do not use a thick gasket paper...

    1990 Force 120HP #2 Cyl zero compression and upon opening piston shows damage

    As topgun3690 says, the water level need to be above the water impeller housing. The impeller is not self priming, it need to bee submerge. Water level need to be at least 1 in above the top of the impeller housing, 4-5 in above the split line of the gear case. Regarding running with muffs. Are...

    Bad trigger? Can’t adjust timing

    The rectifier/regulator can interfere and make the ignition system to act confusing and fail. Outboardignitiondotcom has troubleshooting chart, go through that chart and check out with your engine.

    Bad trigger? Can’t adjust timing

    When I mention magneto I was meaning the trigger ring that moves to advance the timing. I use the wrong word that was why I changed to trigger ring. I suppose your engine has the Prestolite ignition system with 2 CDI boxes (blue or black) and 4 ignition coils. I would suggest you to disconnect...

    Bad trigger? Can’t adjust timing

    Okey, it will start if the spark advance is about 0-4 dgr BTDC at idle speed. But it would not speed up in RPM at WOT if the spark advance is 0-4 dgr BTDC, it would die. As it is starting the triggers are okey if it is running at all 4 cylinders. If the spark advance is 0-4 dgr BTDC at WOT it...

    1990 15 hp Johnson won’t start, sort of sounds like it’s sucking air/leaking air

    Please, please David Wright forget about a bad flywheel key. That key is order, the gap at the top of the wheel is from factory. The length and height of the key will set the flywheel in right position. Torque the flywheel nut to right value and start to troubleshoot the ignition system. As...

    Bad trigger? Can’t adjust timing

    First of all check if the flywheel key is shared. You can do it without pulling the flywheel. Pull the plugs and put a screw driver in top hole (cylinder #1). Find TDC by turning the flywheel CW. At TDC the zero mark at flywheel should line up with the lager line at the timing sticker or timing...

    Reduce kick when putting in gear

    As racerone says, the idle speed is too high. It should be 650-700 RPM in gear in water. Check the compression, it is always good to know the numbers. As you says it stalls when put in gear with lower idle speed. That can be caused by a lean setting of the air/fuel mixture screws. Try to set the...

    1995 force 70 hp ignition help

    That are some of the ranges at your VOM, right? As you do not have a DVA adapter you have to set the VOM at 700V AC when measure the stator cause the stator output is AC voltage. When measure the triggers output set the VOM at 2V AC. If you use a DVA adapter to your VOM you have to set the VOM...

    1995 force 70 hp ignition help

    You can check the output voltage with your VOM, BUT the best is to have a DVA meter or a DVA adapter to your meter. The DVA adapters purpose is to store the peak voltage output so you are able to se the value of it. You can use your meter but you would not been able to se the actual peak...

    What is this part called on Force 125

    As said before that screw and lock nut control the spark advance. On these Chrysler/Force engines you set the maximum spark advance at WOT (wide open throttle). The spec for your engine from factory was in those days with better fuel than to day 32dgr BTDC at WOT. With the fuel there are now I...

    1995 force 70 hp ignition help

    Follow brodmann is a good starting point, BUT NO NO NO 12V AC or DC at the kill switch. This engine has CDI ignition system and there should not be any voltage at the kill switch, if there is the CDI box is bad. Checking resistance (Ohm) at the components gives you some information but to be...

    1997 50HP 3cyl coil test question

    Okey. BTW: The prime side of the coil is a very low ohm winding. The VOM will show very low resistance and you do not know if it is okey or it is a short circuit. The measurement will show almost the same value.

    1997 50HP 3cyl coil test question

    Yes it can ohm out good but still be bad. Remember that when you check the resistance with a VOM you only put out the battery voltage from the VOM, about 4.5, 6 och 9 Volts depending on brand of VOM. The CDI box are putting 200+ Volt to the primery side of the coil. I think you have a bad...

    1990 force 125 shift bellow leak

    Yes, there should be a zip tie to fit the bellow in the grove at the top. Do not tight it to much.
