*****Missing one of the piston rings, but it might be wise to just contact Silv-o-lite and just get new rings for all of them.*****

Part Number(s) Included

  • Silv-O-Lite Cast Dish Pistons 1491H-060 (0.060" Oversize) Piston & Pin Assembly (Set of 4 As Pictured) - THESE ARE 0.060" OVERSIZE PISTONS
    • You can get all of the information in Silv-O-Lite's catalog (Page 87)
  • Connecting Rods (also included as pictured) and I'd imagine they are still the OEM GM ones from the 1972-1989 time period

General Application / Compatibility

  • These were from a mid MerCruiser 3.0L 140hp 181CID
    • These would apply to the 1972-1989 time period as GM switched to a flat top piston in 1990

      • 733-3819 / GM 3963663 / OMC 980503 (Standard)
