I have a 1999 Johnson 30hp (model #J30ELEEC) with damage to the flywheel magnets due to a faulty repair and I have been unable to locate a used flywheel for the motor. My question is, are the magnets replaceable or do I need a new flywheel. I know Johnson does sell magnet repair kits but have no idea if that applies to my 99 flywheel. An input greatly appreciated.
