    Force 40 issues

    Usually when slipping out of gear the edges at the clutch dog and even the edges at the forward gear are rounded, but what I understand you do not get the LU into forward gear. If the clutch dog is worn and the edges rounded it will go into gear but when under load it will slip out. Try to shift...

    About setting the timing, on these Chrysler and Force engines you just set the timing at WOT. Timing at idle will be what it will be. After the timing at WOT you just set the air/fuel mixture and the idle speed. But if you want check the timing at idle with a timing light. My experience is that...

    My experience is to give some throttle and sometimes some choke even if warm. Have a Mercury Thunderbolt 800 80Hp 1972, same actions with it. Some more throttle and sometimes a short choke. Soo this is no issue for me, but remember every engine is individual. Some need a special route to start...

    As you have removed the carbs and intake manifold I would suggest to do the link and sync as Frank A that is in the top of this forum. With the air/fuel mixture screws at 1 1/8-1 1/2 turn out from seated and the throttle pick up point adjusted right it would fire up in about 5 sec with the...

    Some light thru the reeds are acceptable but not to large gap. 0,10mm (0,004in) in my opinion is acceptable. Remember that these Chrysler can be bloody hard to start cold, I think Frank A said this years ago. But if you have to crank 2 or 10-15 sec until it start, does that matter? Were the old...

    Yamaha 25hp 2stroke outboard

    Looking at the video and it sounds like it is misfiring. Do as 99yam40 suggest, check with a timing light. Also check the sparkplugs for crack in the porcelain, change spark plugs, run it in the dark with the hood off and look for sparks jumping to ground (power head). Take a close look at the...

    90hp outboard died suddenly, wouldn't restart

    The engine need three things to run. 1. Air/fuel mixture (right amount mixture) 2. Compression 3. Spark (at the right time) Troubleshoot these three, start with check for spark which is easy. Pull all three plugs, ground them and have the HT wires connected. Turn the key to start and check for...

    90hp outboard died suddenly, wouldn't restart

    You have to check for spark at all three plugs. I sounds like there is no spark. If the stator goes bad you will loose spark at all plugs.

    1986 85hp force 856X6L no spark

    Okey, I have one question. How did you split the CD module and how did you remove the insulation putty? I think it is easy to repair the CD module if you manage to remove the putty. The main components in the CD is the capacitors and the SRC transistors/thyristors and I think these two fail...

    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...

    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...

    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...
