1989 force 125 stator problem

[new outboard guy]

I have a force 125 outboard. the motor was bogged down and would not go above 2000 rpm. pulled the flywheel and found a burnt spot on the stator. I found a new one but am wondering what may have done this or if there is possibly another hidden problem. any help would be appreciated.

I have a 89 125 that also will not go past 2000-2100 rpm. I plan on checking out the ignition system tonight. Let me know if you find anything. Be sure to check the marine doctor forum too.

Re: 1989 force 125 stator problem

One thing that will do it is if you are testing the ignition without the plug wires on and the wires not grounded. This sends a feedback that will damage the cdi module and the stator.

Always ground the plug wires when timing or any other time you should rotate it with the wires or plugs removed.

Re: 1989 force 125 stator problem

I never checked any of the wires before the stator burned up. I was actually on the lake when it happened. Ran fine for a while then started running like crap. just hoping that the stator is the only problem, trigger looks good. any more help is greatly appreciated

my force 120 is having the same problem. whats the process to get to the stator?

New outboard guy.

Other owners before you could have caused the damage or your stator might have had a manufacuring defect. Electronics are funny creatures.

You need to buy a Clymer manual if you are going to work on this engine. To get to the stator, you will have to use a gear puller to remove the flywheel.

John md-
Is that what you think the problem with my 120 is? i cleaned all gas lines and found nothing clogged..but last time i ran the motor at the lake it was smoking really bad? what could have caused that?

 

[john from md]

Re: 1989 force 125 stator problem

Smoking really bad can come from several things. I will list a few of the most common.

1. clogged fuel recirculation system. The older engines with cross flow induction had this system. You will have several small diameter hoses running on the side of the engine. Also on one side there is usually a vertical cover about 11/2 inch wide that contains the cylinder drain valves. If any of part of this system is clogged you get hard starting and more smoke.

2. a torn or perferated fuel pump diaphram.

3. a cylinder not firing. This can be checked by pulling off wires in succession and determining if one does not affect the engine when removed.

Hope this helps,

John

Re: 1989 force 125 stator problem

The process i went through to get to the stator was remove the lock nut, then knock the flywheel off with a dead blow hammer. came off fairly quickly, and no damage to other motor compnents. a gear puller is a better option, but really soak it down in a good oil like wd 40. found that the stator was burned where it goes into the coil where it controls the 1 and 3 cylinders. found a stator brand new for 138.00 online. will update condition when the stator is installed. thanks for all the help guys!!!!! matt

Re: 1989 force 125 stator problem

NEVER USE A HAMMER ON THE FLYWHEEL!

The magnets that are epoxied onto the flywheel will break from the flywheel being struck with a hammer. If they don't fall off immediately, you stand the chance of them falling off while you are on the water.

Use a gear puller and do it the proper way.

Re: 1989 force 125 stator problem

one last question. when i go to put the new stator on how do i do it and not break off anything on the stator. i dont want to damage anything.
thanks for the help. matt

Re: 1989 force 125 stator problem

Just follow the manual and you will be alright. Just don't pry or bang things with a hammer. A little wiggling here and there is ok but don't force anything.

John

BTW, with boats, there are no last questions.

Re: 1989 force 125 stator problem

i only hit the flywheel to get it off because i knew the stator was bad. so i just need to wiggle it back on and test??? hopefully all goes well and thanks for all the great help!!!! much appreciated

Re: 1989 force 125 stator problem

When you reinstall the flywheel, line up the woodruff key in the slot and work the flywheel down over it. When correctly installed the key should be even with the top of t he flywheel. You can tap the top of the flywheel down(with the hammer handle) once the key is showing and about 1/8 inch remains. Then install the hardware and torque to spec.

FYI I found what was causing my 2100 WOT problem. After following the service manual troubleshooting section I eliminated all problems except the carbs. I found a stuck needle in one of them. Took it apart, cleaned off the varnish and reassembled. Runs great now. Get a manual it's worth it!

Re: 1989 force 125 stator problem

well i finally got a manual for my motor, and found out my trigger is bad also. that really sucks. tested at 43 ohms, book said it should be between 48-52 ohms. did the resistance test too, and it was open. just sucks my stator was bad too. hopefully ill get it fixed soon and test it in the garage. thanks for all the help everyone!!!

Re: 1989 force 125 stator problem

There have been several stators and triggers for sale on ebay. People part out engines that need too much work and most of the time the parts go for reasonable prices.

Good luck,

Re: 1989 force 125 stator problem

so will the trigger cause my motor to not rev up over 2000 rpm??? and why is my 2 stroke motor leaking oil on the floor??? checked the lower unit, and no leaks. could it be the trigger causing cylinders not to run properly???

 

[john from md]

Re: 1989 force 125 stator problem

The oil on the floor, if it is dark, is probably unburned oil dripping from the exhaust snout or lower cowl.

The trigger tells each CDI module when to fire its attached coil. Yes it can cause your engine to run at a lower rpm but so can several other things. If you have checked the trigger per the maintenance manual and have different values than the book, chances are it is bad. But, the CDI module can also be bad so it needs to be checked.

Re: 1989 force 125 stator problem

could the cdi module also be called the cdm module??? and could the rectifier be causing the problem also??? or what else can cause those problems???? cause i do know the trigger is bad.
