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.
