Removing lower unit wont seperate

Sounds like an impeller and seal kit you will need I think you impeller jammed up and the shaft stripped out the impeller or your motor shaft snapped

I’m happy to help further over the phone at https://www.6ya.com/expert/george_106a9535a98aec8a

yes this is common for the whirlpool duet... if you remove the front cover lower cover that is you will see 2 maybe three screws at very bottom of unit.. once you remove this you will see a round shaped clean out that has a handle on it... prior to removing this make sure unit is unplugged and you have several towel in hand because there will be a gallon or two of water come out...if you have a shop vac they come in great hand for this project. vac all the water you can out of the tub and then have it ready when you open this clean out.. look inside for any foreign materials (ie: coins,bobby pins, i have even seen women metal bra linings get it this area) check the hose while your in there for anything and reach up into pump area and make sure nothing is in impellar..hopefully you find you culprit here ..sometimes trash will go through the pump and made out of plastic will damage plastic impellar and requires a new drain pump assembly. maybe you have caught it before that..... good luck give me a feed back thanks

There is no special tricks.Unbolt the gearshift linkage that has access through the side of the leg.Usually a small plate.Unbolt the lower g/box.4 bolts I think.The box should then drop.If not,use a rubber hammer and be patient.Put the lower skeg of the g/box in a vice to make things easier.NOW.When you lift the housing of the w/pump take a note of which way the impellar pump lobes are curled.DON'T put the new impellar in the wrong way.It's probably worth putting in a new seal whilst it's apart.You spin the housing or imp. as you put it together.Use a small bit of grease for the initiall dry start-up.Put some very good grease on the top splines on the driveshaft.It goes straight into the crankshaft.If it corrodes,nothing comes apart.As you put the g/box back on,spin the prop so the splines go back in.There is no special alignment.Gearchange linkage and you go fishing.(take the prop off and regrease the splines on the shaft of it)Hope this helps

Put the motor in neutral.On the leg of the motor there is a little side cover plate.Remove.Undo the bolts.This is the gear change linkage.At the cavitation plate,there is 4 bolts.Remove.If the lower housing does not drop,give it a soft whack with a soft hammer.When dropped,you will see the prop shaft and the gear linkage.Lower it all the way out.Its easy to work on if you put the lower skeg in a vice.Take the water pump apart BUT!!! have a look at which way the impellar blades are pointed.Grease the new impellar as you put it back in and turn it at the same time to get the nodes in properly.Heaps of grease to protect all the bolts.Makes it easier next time.Hope this helps

Hey I just got the same motor and actually have the same exact concerns. Have you found any answers?

goto local library get book on unit!!! :)

you need to find out if they just replaced the water pump impellar or the whole impellar housing make sure bolts are tight at mating surface what may have happened is the impellar tube may have not been lined up correctly during installation does the motor get hot let me know so i can figure it out theres only so many things it could be but if it stops pumping youll be in trouble comment me back

Dropp the lower unit, should be only 4 bolts holding it on. Impellar housing should be located right on top of the lower unit. four screws it the housing slides off the shaft, insall in reverse order with ne gaskets, make sure you re- align the waterhose/pipe from the lower unit back to the head

Can you verify that the radiator fan is coming on when needed? Your Mystique has an electric radiator fan. A sensor on the engine tells the computer to turn on the fan. If it is overheating in traffic or at speeds lower than 45 mph, you fan is probably not working when it should. Your mechanic should be able to tell with a scan tool if the computer is turning the fan on or not. Most likely culprit is the fan relay, but I've seen these with a bad fan motor also.
