    I have a 1984 Mariner 15 hp and I want to replace the coil which is located under the flywheel i was told. I have the top plate off and the middle nut loose. I just can seem to get the flywheel off. Is there something I'm missing to remove,screws etc? I don't have any kind of puller so I have to do it another way. Someone told me to pound it off but dont want to bend or ruin it. I was told you are the Guru to ask.
    Also, i have never done this before but learning as i do it. Thank you in advance for your time.

    Personally I made myself a make shift prybar to get mine off. Fairly heavy piece of steel ground thin enough to fit under edge of fly wheel.Leave the nut on top of the shaft so you don't mess up the threads then take a fairly good size ballpin hammer and hit nut fairly hard. Shouldn't hurt the flywheel and hoefully it will pop lose.Least mine did. Make sure you hit nut square and solid. But if Bubba ahas a better way better listen to the master.Good luck and be careful.Why its hard to get off is there is a flywheel key on the side of the shaft holding wheel on.Don't lose the KEY!!

    If it was me I reckon I would hit the local "chain" auto parts store and see if I could "rent/borrow" a puller that would work.

    Quite a few auto stores have little "value" bins that have small pullers in it. Those three holes on top of the flywheel are for the puller, and frankly, your just gambling when you try to remove it in other ways. Sometimes you can take the part to an auto zone parts store and they will remove the flywheel.

    you can get a crows foot puller or a harmonic balancer puller which is the same thing for about 10 bucks i wouldnt go prying on it or hitting it with a hammer

    proper tools usually cost less than the damages caused by using the wrong ones. Not every time but its safer and cheaper in the long run to use the right equipment.

    I just had a time pulling a flywheel off a riding lawnmower. Most auto parts stores have tools that you can use free...just ask. You pay for it when you get it, and they refund the fee when you return it. After I got it off, I got advice from a guy at work who does a lot of motor work. He said get someone else to lift up hard on the flywheel at the side with the keyway with a large screwdriver. Then hit the shaft with a hard bouncing blow. When you put it back on, you don't need to torque the nut down all that tight...snug plus an 1/8 turn.

    DON'T pound on it...get the right puller. if you hit it with a hammer, remember you are pounding on the crankshaft...it is held in place by bearings....every blow is harsh punishment on block, crank, and bearings.....don't waste a good motor 'cause you won't buy the right tool.

    Go buy or borrow you a harmonic balancer puller and get the right size bolts that go in the fly wheel and take the big nut off and set the puller up ans squirt some PB blaster on top where the big nut was and let soak for a few minutes. If you will wait a few hours on it I will upload a picture of the pulling set with the proper torque to reset it and you will have to clean the the tapered part of the crank with some fine sandpaper before reinstalling the flywheel
