Due to the fact of the cost and availability I am contemplating changing over my late 70's early 80's 40hp mariner/yamaha from points style ignition to the stator type ignition. I have located a stator plate with all the necessary electonics on it for a VERY reasonable price. My question is do i have to change the flywheel or anything else to do the swap or is it even possible. I know I would have to also get the primary coils as well. If anyone can please give me a list of all that I need to make this swap over please email me or respond here. My email addy is wareagle50@hotmail.com and once again thanks for all the help folks. The lower unit swap went SO WELL with you guys expert help and it runs great if I can now get the top end right.
