Distributor tune up kit for 1986 and older Indmar (ford) marine engine - includes new distributor cap, rotor and advance tuning kit. I purchased the kit for my 1987 mastercraft prostar with Indmar 351 but fit is not correct and I missed the window for returning the parts to bakes marine online (the distributor on my boat currently is not stock and was trying to match parts from photos, as it seems that someone had replaced the distibutor at some point). Parts are unused
