    Force 40 issues

    When you rebuilt the LU did you changed any parts in it? These LU do not have any shim at either prop shaft or drive shaft. But there are two thrust washers at the prop shaft. One at each gear in front of clutch dog between the gear and the prop shaft. Are they in the right place now? If you...

    1990 Force 120HP no spark NEW stator tests 0.5V between sets open resistance this is crazy HELP

    That inner magnet/laminated core for the triggers does not looks good. You have to fix that otherwise it will chew up the trigger assembly again. Best is to change the flywheel, in my opinion hard to fix that magnet/laminated core in that flywheel.

    1979 80HP Mercury

    When you are in the lake (water) you have back pressure from the water to the exhaust. On muffs.......no. As jimmbo and racerone says, check the compression and check for spark at all cylinders.

    Force 125

    Your engine is a 1984 year model. The allen screw is the drain screw and the went/level screw at the starboard side just above the cavitation plate (flat screw). The "no no screw" whitch is the swiwel for the fork that change the gear is at the starboard side at the gear case bullet. Unhook the...

    Reeds?

    Okey, try to give it a little bit of throttle when starting.

    Do you give it a little bit throttle (pull the knob and give some throttle) when staring it warm or just idle?

    1991 150B force outboard no spark

    Do you have Prestolite ignition system with three blue or black CD modules? Or do you have Mercury Thunderbolt system with one switch box? Normally the CD modules or switch boxes can not be tested from resistance with a VOM. You test for voltage from the stator and triggers to the CD...

    Force 40 issues

    Not really hard to pull apart. Just to be careful when pulling the propeller shaft cover. Make a puller for it, do not twist the cover to try to turn the cover a bit and try to pry the cover off with a screw driver at the mounting tabs. Really large risk you brake the tabs.

    Force 40 issues

    As you describes and I can not feel and se you engine it sounds like the edges at the clutch dog and/or the gear is worn. BUT hard to give a good advice.

    Electronic distributor made a buzzing sound

    Yes that maybe is possible. I also do not know if the triggering of the CD box is when the photo diod in the preamp goes from covered to uncovered from the disc or from uncovered to covered by the window. The troubleshooting says if I do not remember wrong to use a credit card to simulate the...

    Electronic distributor made a buzzing sound

    But, but there is no points in the distributor as it has the preamp. The electronic distributor has a disc with 3 windows in your case as it i s a 3- cylinder engine. The disc is running through the preamp and the photo electric diod in the preamp is "reading" the windows and trigger the CD box...

    Electronic distributor made a buzzing sound

    Yes, try Bill Kelly and why not Franz Buddenberg at Franz Marine Service. Franz is a Chrysler/Force guru.

    Electronic distributor made a buzzing sound

    Okey, do not think a troubleshoot will give any answer. It only cover if you have problem with the ignition. If it works and will sound when you start it up just run it. That is what I would do if it was mine engine. Maybe time to catch up one for spare. The bad think is they are pretty...

    Electronic distributor made a buzzing sound

    Never have experience of buzzing sound from the distributor. Do you have the OEM preamp or a preamp from CDI Electronics? Very early Magna Power CD boxes from Delta with the two transistors mounted outside the box and this is when the Magna Power was introduced in 1967-1968 and they were on the...

    90hp outboard died suddenly, wouldn't restart

    I am not very familiar with these engines but you maybe have two stop possibilities. Keyswitch to stop (left position of the key) and the stop switch. To rule out if it is problem with the stop circuit you can disconnect the stop wire to the switchbox and check for spark. Looking at my...

    90hp outboard died suddenly, wouldn't restart

    This engine suppose to have three ignition coils one for each cylinder. Seams odd if all three coils will go bad at the same time. Check the kill switch, it can fail over the time. When the overboard lanyard key is in place the circuit should be open. When activated it ground out the switchbox...

    1955 Evinrude Fleetwin 7.5hp carb kit?

    Fleetwinner the compression numbers are also important. These small engines should be in range 80-120 PSI maybe higher, but most important is that the numbers are close to each other. Not more different than 10-15% is a general rule. They will run with 80PSI but 100PSI or more is preferable...

    WinnerCougar74, do not blow it for a Japanese Yamaha 4-stroker. Handle it with care and do not run the hell out of it. You are doing a historic nostalgic deed to preserve it.

    question on the starting a "2 cycle Merc" sticky

    We in the old generation 50 or 60+have the knowledge about carb engines and how you maybe have to start it and troubleshoot in a logical way. . The new generation ???? Sad to discover that we will go to a computer troubleshoot generation that will be a random part changer.
