Did some checking today and I believe I have a Mallory distributor on my 1989 OMC 2.3 I/O. Can y'all tell me if the standard replacement ignition tune up set shown in the OMC catalog will fit? Or are they only for Prestolite distributors? If they won't fit, does anybody know where I can find a replacement set for my boat? Unfortunately I forgot to get the numbers off my dist, but from some research I think it's a YL series single point.
