    89 Force 50 HP Flush Muffs?

    Jerry's pics is the only kind of muffs I use for my 125HP. I've tried the other muffs even the expensive one but they do not work. The simple solid thick wire with only one water connection is the only one that works perfectly for my 125HP that has the inlet holes on the "bullet" gear case. A...

    89 Force 50 HP Presolite T/T valve body leak

    Always remember this rule of thumb when reconnecting these lines, ALWAYS MAKE SURE OPPOSITE END IS THREADED IN LOOSELY TO GIVE YOU A LITTLE WIGGLE TO PROPERLY ALIGN THE THREADS ON THE OTHER END. These are stiff lines that has very little to no wiggle at all when tightened on either end. As...

    89 Force 50 HP T/T not working properly

    So what was wrong with the DB motor and pump? Like mentioned before, if the motor does not reverse you need to check the wiring especially on the relays. Reversing of the motor is accomplished through the relays and not necessarily on the motor itself.

    89 Force 50 HP Presolite T/T valve body leak

    Just a reminder, it is not the thread on the coupling that is providing the seal to these hyd lines. Instead, it is the flared copper tubing that is pulled against the valve body that provides the seal. I could be wrong but as far as I can see the hyd lines are flared and are supposed to go...

    89 Force 50 HP T/T not working properly

    Check the wiring on the T&T motor to make sure it reverses rotation when pushing the, "Down" button. To confirm this, you can also try this: while in full down position (or at mid up/down position), push the "Down" button and see if the T&T goes up. If it does, then T&T drive motor is not...

    1986 force 125hp outboard

    Here's a wiring diagram for 125HP supposed to be good up to 1989 models. Ignition SW wiring is on the upper right side of the image.

    Bet up by a 1998 120hp force

    This could be fuel related . . . i.e. the bogging down on fast throttle. But it could just be an adjustment of the idle air mixture screw. First and foremost if you haven't done it yet, install a clear fuel filter between the fuel pump and the carbs intake. It is more for troubleshooting than...

    1990 Force 90 Won't Crank -Binding

    As mentioned, drop the LU first. And then try again. If it is still binding then remove the head and do an inspection of the cylinders and pistons.

    Force 85 not firing on cylinder 3

    That is correct.

    Force 85 not firing on cylinder 3

    Interesting. So in this case the OP should switch to the spare CD Mod circuit and see if the spark will return. If not, then as suggested by Jerry switch over the CD modules and see if the problem follows. If it does, i.e. no spark on 1 & 2 cylinders, then the problem is the CD module. This is...

    Force 85 not firing on cylinder 3

    I've always been intrigued by this wiring diagram. All along I suspect there's a jumper between the blue terminals, hence the two blue wires were just crimped together and connected to one of the terminals. But then I also checked the 90 HP and it has basically the same wiring, two blue wires in...

    87 Force 85hp Flywheel removal

    And the use of a balancer puller with 1/4"X20 grade 5 or 8 bolts should always be your first attempt. And the 2nd attempt should be with enlarged 5/16 X 18 grade 8 and lastly should be the two or three claw bearing puller. Glad you made it through the first attempt.

    87 Force 85hp Flywheel removal

    If you are referring to the three holes on the flywheel used for pulling, it is 1/4" X 20 TPI. You might want to get one 1/4" X 20 TPI bolt first just to make sure.

    Piston tool for Chrysler 75 hp 757HB

    +1 and the fact that Wiseco piston rings are readily available. Not so much with the original Chrysler rings.

    Piston tool for Chrysler 75 hp 757HB

    Not familiar with Chrysler but I believe they are identical (though different sizing) with the Force pistons. I also just finished changing all my pistons on 89-125HP Force. But didn't have to use that T2990 tool. Not sure if you are replacing the pistons with original Chrysler pistons but in my...

    89 Force Tilt/Trim Pump

    Might want to open and inspect if there is anything missing gasket or o ring or could have just been improperly torque (cross torquing) before you end up with a broken bolt. If there's anything I dread is a broken bolt especially, tiny ones.

    carb adj 1997 50 hp

    Glad to hear you're OK. Based on reports, the destruction left by the hurricane is unimaginable leaving millions without power. Hopefully, recovery will be expeditious and smooth.

    Tachometer on 87 force 85

    Not sure about this but as far as I can remember the tach on the 85HP is a 12-pole signal from the stator. So you can do your conversion base on this info.

    carb adj 1997 50 hp

    Well, let's make sure we are talking the same screw, i.e. the idle air adjustment screw. Technically, according to the manual the lowest setting should never be less than 1 turn out from lightly seated. Normally, for most people that is, the setting is between 1 turn out to 1 1/4 turn out...
