Looking for a complete tune up kit for a 1990 Mercruiser 7.4L Blue Water Inboard. What is a good after market brand or would the group suggest ticking with OEM? By complete kit, meaning Cap, rotor, plugs and wires.

I wouldn't try to find a kit, just go to your local auto parts store for everything except the cap and rotor (Just my opinion)
Plugs AC Delco MR43T or NGK BR6FS
Wires any quality wire set (7 or 8mm silicone jacketed) for a 1990 7.4 or Merc 84-816608Q61
Cap and rotor I would stick with OEM Cap 805759T1 Rotor 13524T1
