    1986 85hp force 856X6L no spark

    Sounds like you have one output channel at one CD module that is bad. Each CD module has two output channels soo a two cylinder engine need one module, a three cylinder engine need two modules but one channel is not in use and a four cylinder need two modules and use all output channels. Try to...

    Reeds?

    I use razor blades, pocket knifes or putty knifes when removing old gaskets at smaller parts. At lager parts/surfaces such as bottom of power head to midleg I use a tool made for removing gasket when restoring car engines. Most important is that the surface is smooth and clean. Some sign of the...

    can starter spin fly wheel just fast enough for stator to show power but not trigger the triggers?

    I do not really know the answer of your question but I think if the starter turn the flywheel fast enought to generate power to the CDI modules it will be enought for the triggers too. The trigger voltage has to be 0,5VDC DVA or higher to trigger the CDI modules. The starter has to turn the...

    Mercury 80 won't crank with plugs installed

    4 stroker can be filled through a bad float needle if it is carb engine or through a bad injector and an open intake valve. Have hade this kind of issue, but it was a B&S engine on a lawn mover. Especially if it has an over head internal fuel tank (no fuel pump). Crank case was filled with about...

    1987 mercury 45hp classic 50 shut off in the middle of running

    I have had that kind of issue with two smaller Mercury. One 9,8Hp 1977, started fine and ran for some minutes then shut down. Put it in a large bucket and force heat to the switch box with a heat gun. Shut down after some minutes. Similar issue with a 20Hp 1976, shut down after avail. Did the...

    1987 mercury 45hp classic 50 shut off in the middle of running

    You have to check for spark when it shuts down. The switchbox could fail when getting warm and it loose spark. When getting cold it will work for avail again until it get warm. Have to figure out if it is a spark issue or overheating issue. Seams to be a spark issue as if it is an overheating...

    70's PenYan

    Force 115Hp, than I think it is a engine post 1984 and pre 1987. Are the color of it white? Force is a rebanded Chrysler engine, Chrysler had to sell the outboard division in early 1980es. 1984 was the last year with Chrysler name and the outboards was sold to US Marine. The engine is very...

    what motors are compatible with the 88 125 force?

    125Hp has 3,312 in bore the 120Hp has 3,375 in bore. Many parts are swappable but such as carbs can be different typs, Walbro or Tillotson brand with different part numbers. Gear cases can be different too with different ratio. If I do not remember wrong the 120Hp only had 2 piece drive shaft...

    Fuel for older Evinrude/ Johnson

    matt167 yes I know that the octane value has nothing to do with the age of an engine, but here in Sweden the fuel today is worser than it was in pre 70s, 70s and 80s. My experience is that you have to retard the spark advance with todays fuel to be sure you do not got detonation due to...

    Mercury 7.5 HP, 9.8 HP Flywheel P/N question

    Nice, the important thing is that the flywheel is for the right ignition system. Older 7,5 and 9,8Hp used magneto system (no electronic system). Maybe not the 7,5Hp, it was introduced in 1969 or 70 and in this era the electronic system became common on smaller engines. Think the 7,5Hp, 9,8Hp and...

    Fuel for older Evinrude/ Johnson

    The engine it self will handle 10% Ethanol gas, but all rubber hoses, fuel pump diaphragm etc parts that are made of or has rubber in it will be affected by the ethanol. All old parts that not are suppose to be in contact ethanol will swell after avail. Rubber parts that not are made to stand by...

    I'm stumped, please help. 1996 40HP force outboard

    Check the flywheel key. I think it is shared. Flywheel zero mark at zero mark at the timing plate The top piston should be at TDC. Check with a screw driver.

    70’s Mercury 850 Thunderbolt - Distributor Wires

    Check out youtube and search Mercson. He has alot of videos about Mercury 4 and 6 cyl. There are some how to check the 4-inline and 6-inline switchboxes and distributors (battery system not the ADI). You can power the switchbox and connect the distributor to see if they works.

    I'm stumped, please help. 1996 40HP force outboard

    I have not work with these "new" Force engines so do not know them so well. Think you have Mercury Thunderbolt ignition system and not the Prestolite system. I think but not 100% sure that the magnets in the flywheel are glued. Maybe some of them are loose and have moved. If you have a timing...

    79 Chrysler 115 Won't go into gear

    Does this happened suddenly, is it a new engine for you? Does the remote cable for the shifting make the full stroke? Maybe there is something wrong in the gear case. Disconnect the remote cables and shift by hand a see if it make any different.

    1986 85hp force 856X6L no spark

    Check at outboardignitiondotcom, they have a troubleshoot chart for the ignition system. You can check out the resistance with a VOM, but best is to have a DVA meter or a DVA adapter with the VOM and check the output voltage from the stator.

    Tillotson TC-5E float needle valve

    Read the Link and Sync adjustment by Frank Acampora in the Force & Chrysler FAQ and other great information in top of this forum. This is a clipping from the instruction . 10. I can NOT stress this enough! NEVER set the low speed needles less that 3/4 turns out no matter how poor the idle or...

    Tillotson TC-5E float needle valve

    From my experience and in my opinion these plugs looks good from just running at slow speed and as they are not "burn brown/grey" the engine has not been at higher speed with these plugs. I would suggest you to set the air/fuel mixture screws at 1 turn out. With they at 7/8 turn out there is a...

    Sea-king Chrysler 15hp outboard motor does not start

    Maybe you put to much fuel in the spark plug holes and it is to rich mixture. Have you put the right HT wire to the right cylinder? Is the flywheel key in good condition, not shared. Does the spark jump 1/4-3/8in in atmosphere?
