MerCruiser 140hp 3.0L .060" Oversize Pistons 4cyl 1491H-060 Silv-O-Lite 1972-89
*****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
