    Carburetor float question

    Just as Jiggz says, the float should be parallell with the body when inverted. The first and the second from left need to be adjusted.

    1989 ish Mercury Force 120 ignition issues

    There are no way to check the CD boxes, they can dump voltage to the coil as your are doing but if the blocking diod is bad it interfere the other CD box and you got issues like you have. The blocking diod is in the CD box, almost impossible to change. The purpose of the diod is as I said before...

    Sat for 30years

    James Rider, no my mistake about the curved line at the pulley, I must have thought about something else, sorry. At WOT it would not align but the spark at top plug at WOT should come at 30 dgr BTDC.

    Sat for 30years

    Correct timing is when top piston is at TDC, then the curved line at the distributor pulley should line up against the flywheel rim and if you have an arrow at the pulley it should be pointing to the flywheel rim perpendicular. This is the basic setting. Then you set the spark advance at WOT...

    Fuses in Tilt Wiring

    Add a fuse to both of the positive wires from the relays to the motor. Put it in line if that is easiest way to do. You can check have much current the motor need when running and put a fuse that has just a little bit more current value. Have in mind that there will be a current peak in the...

    If you now have a T&T unit (Trim and Tilt) the reverse lock is not needed. Remove it or disconnect it. You can check the different between manual tilt and T&T at Crowley marine. Look at Mercury outboard, Mariner and Mercruiser parts online then go for Force outboard 1991 70Hp.

    Recommendation on Force Sealant for Crank

    There are a lot of seal for this application. Loctite 518 as racerone suggest is one. I use Permatex Aviation Form-A-Gasket no.3. The package has a built in brush in the cap and easy to apply.

    Force 85 (1985) Doesn't like to do more than idle in water - and often dies on its own

    As you have checked comprerssion in all 3 cylinders and it is 145 PSI the next step is to check for spark at all 3 cylinders. If spark is okey then clean the carbs, check the float levels and then set the air/fuel mixture screws at 1 1/4 of a turn out from lightly seated. Then you have to set...

    Super Ugly Pistons

    ForcedError melted/detonation pistons are a result of either lean settings of the air/fuel mixture screws of not right set of the timing. It can also be both of this issues. As you says the reed valves are not sealing tight and you can see daylight through them. A little bit of gap is acceptable...

    Lost the yoke

    You have two options. First pull the LU from the engine, remove the water impeller housing then remove the top cover of the gear case. Then maybe you can catch the yoke and put it in place using marine grease. BUT be very careful when you remove the top cover, you maybe break it if it is tight...

    Hi all so back kind of after a rebuild as found broken rings not causing any problems but once seen

    125 A 19 p prop maybe to big, depends on load. For skiing you maybe need a 17p or 15 p to have enought of RPM at the prop in the start. You loose about 200 RPM in every inch of lager pitch of the prop, BUT you got more top speed. A tach will give you the answer, WOT about 5200 RPM and you have...

    73 Chrysler 85hp won't start

    Check the flywheel key. Might be shared. Set the top cylinder in TDC. The curved line at the distributor pulley should line up with the flywheel rim. If not the timing is off, maybe the flywheel is shared.

    1990 50HP Force Starts but won’t stay running

    First of all check for good spark at both cylinders, then check compression. If you have compression and spark then check the flywheel key. If it is shared, then the timing is off and it would not start even if spark, compression and fuel delivery is okey.

    1990 Force 50 HP Bearing Cage Kit Replacement

    I think that black rubber seal is the rubber boot seal which suppose to seal the drive shaft spline up against the crank. Part number 819293. There are no more seals for the water tube to the impeller housing then the white plastic one with part number FA 485914. The black rubber boot seal is...

    Force 85 1989 flywheel magnet pain

    That ignition system is the one Mercury started to put on the Force engines in I believe 1991-92 (Thunderbolt ignition). It has a more reliable reputation then the Prestolite system which the engines was equipped with before. In my opinion the Prestolite system was as good as the Thunderbolt but...
