I just noticed on Amazon that they have the Mercury Marine Vortec caps and rotors under the Quicksilver label. My Delphi cap and rotor did not last long, these are pricey but perhaps last longer?
Link or part number?
I've always used AC Delco on my truck, and have had no problems. I would assume production would have been by Delphi, but given Delphi has changed so much over the years that may not mean much now.
