    Identifying Chrysler 45 hp Outboard year and Model Number

    If the hood is the right one the engine is from 1971-73. It is a Chrysler engine, after Chrysler sold out the OB manufacturing and US Marine took over they named it Force. But all models were basically Chrysler engines with another name.

    Identifying Chrysler 45 hp Outboard year and Model Number

    Your engine is a 45Hp with battery ignition and alternator. The magneto model did not have alternator because the ignition coils are mounted under the flywheel. Looks like the year is about 1970 until 1973 but a pic of the hood with the decals would be great. It also has the old style fuel pump...

    When shuts down check if you have a spark issue or fuel issue. Put an inline fuel filter after the pump and before the carbs. This will help you to see if it is a electrical issue or fuel issue.

    1989 ish Mercury Force 120 ignition issues

    When I rebuild or do anything with an OB that has to seal or reseal something I use Permatex Aviation no 3 form a gasket. My experience is that it is useful at the engine block or at the LU. It is easy to use and apply cause there is a brush built in the cap.

    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...

    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...

    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...
