My 89 Evinrude 25HP retainer link assembly spins to far with flywheel movement.
I replaced the power pack in May which was under the flywheel..
Ran great, but now the retainer link assembly spins to far so motor wont start...
It snapped the throttle assembly at the back as well.
This retainer link assembly is the one that moves with the throttle and has the wires from
the power pack attached...
Any thoughts on why this assembly is moving out its normal range of motion?

Thx

Re: 89 Evinrude 25HP retainer link assbly spins with flywheel

I assume the assy you are talking about is the stator mounting plate , if this is correct, the only reason for it to spin is that it is somehow making direct contact with the underside of the flywheel, or the coils are making contact with the flywheel magnets (which it should not),, it will however try to move under the influence of the flywheel magnets but not with the force you mention,, I would remove the flywheel and check for scouring , and you may well find that because of loose components the stator is trashed, it should be able to rotate BUT not have any lateral movement, this obviously will be the cause of the non start,, let me know what you find and good luck,

Hi,

I replaced the USL 2unit on my 1992 evinrude due to ignition failure, It took ages to get it all right as the original unit had worked loose and trashed the flywheel, removing the ignition pick up on the ignition unit, It sounds like you have had the same miss hap.

Good luck with finding the fault also I would recommend the replacement of the woodruff key on the flywheel and crank at the same time as these are not that strong and it may well be damaged.

All the best ukmember

Re: 89 Evinrude 25HP retainer link assbly spins with flywheel

finally got around to removing the flywheel.
The flywheel has hit the new power pack and broke it loose
from mounting screws.
The old power pack was touching the flywheel and became defective.
We mounted the new one in closer, away from the flywheel but
it still caught it and is the reason for everything moving together.
There is a little play on the crankshaft...measure about 3 thousands of an inch.
Not sure why it keeps hitting the power pack. Is that enough to do it?
Was think about getting the kit to mount the power pack on side of motor, but
not sure if this motor is toast...
The flywheel is also touching one of the magnets on the left side and in front of the power pack.
Sanded down inside of flywheel when replaced the power pack.
Any thoughts?
thx

Having had the same fault as you Iwould say go for the aftermarket type from engineroom.com

Mine started playing up again today whilst 5m from shore, I always have an aux engine so got back, Again i also have a bit of play on the crank, but not as much as you, In the OEM manual there is a tool to get everything alighned.

The aftermarket unit just has the pickup on the underside of the flywheel, with the cdi on the outer to stop these from geting mashed, seems a common problem after speaking to a Rude dealer in the uk

Try this link and put in your cd2 usl number to cross referance http://www.mareng.co.uk/electronics-power-pack-584489-1134489-p-137.html

CDI Electronics OMC Power Pack CD2 USL 584489 (113-4489)

Edit ........ I also replaced the flywheel mine was damaged and grooved, did think about getting it skimmed but couldnt find anyone to take it on......Hope it helps

thanks for response...

didn't think about the pickup.....do you think
it will be in jeopardy of getting smashed as well since it is sitting where pack would be?

I know there is kit to mount the power pack on the side of the motor...
Does this kit also include a pickup....

thx

Dan,

The great thing about the after market unit is that the pick up is available on it's own, so costly full kit to buy.

It is smaller than the CD2 USL unit going to have to order mine next week as i think mine is u/s as well.

I was lucky to get a 2nd hand motor which had a flywheel etc that was in good condition but the cd had burnt out,the previous owner of mine was a spanner weilding maniac who had hit the flywheel from the underside to remove rather than buy a ?20.00 flywheel puller.

Good luck this is a great site for advice.

Throw the whole UFI powerpack system in the garbage!
Get an 'old' type ignition system from a junk yard.
It was at least one reason the system was finally scrapped and they returned to the old system again:
Exactly what has happened to you!!!

Re: 89 Evinrude 25HP retainer link assbly spins with flywheel

what "old" type of ignition system would work ?
Is their a year and model I can duplicate?

I really think the pickup will get trashed as well...
I still cant believe it snapped the new pack , especially when it was inset a 1/8"
behind the front of the magnets...The screws were still tight holding the broken plastic in the same place.

Close to anything from a 20/30 from 1981 and up to 2000+, just not the UFI!!
Any salvage yard or junk dealer should be able to help.
Best if you get an armature plate complete with power coil, sensor coil and charge coils. Then just add an exterior power pack.

I called a few places with used parts.
I was told that the older models with the pack mounted externally still have the pickup in the same place where the pack
should be on this model...
still concerned it will smash pickup as well.

True, but I have never seen the old system coming loose the way the UFI does!!!
Not to mention that the 'old' parts are a fraction of the UFI price.

When my replacement CD2USL unit arrived it came with the correct mounting screws, with serrated washers and i still used a small tickle of loc tite on the threads.

Yep you guessed it still came loose, when this pack bites the dust im going for the complete kit i listed in an earlier thread.


Good luck, still debaiting weather to but another motor or repair again.

Re: 89 Evinrude 25HP retainer link assbly spins with flywheel

the thing is, my pack didn't come loose.
It broke off plastic around both mounting screws that were still tight and
still in place. (I inset 1/8th of an inch so I could tell still in same spot)
I am buying a new motor, but was wondering if I should bother
to fix this one...
right now, thinking not a good plan...
the price of used parts are too expensive here in Canada
to go back to old method... and a new pack with kit is likely
going to be a waste of money...
probably better to sell off parts and retire this pain in the .... :)
