Product Details

The Quicksilver 8M0204700 is an OEM propeller shaft seal designed for Mercury Marine outboard engines and gearcase assemblies. This critical seal prevents water intrusion into the lower unit while retaining gear oil within the gearcase housing, protecting internal components from corrosion and premature wear.

Key Features:

  • Fits 135-300 HP Verado outboards, 150 HP 4-Stroke EFI, 200-250 HP 3.0L DFI, and 175-300 HP V6 3.4L and V8 4.6L engines
  • Seal dimensions: 31.7mm x 42.9mm x 6.5mm
  • Stainless steel internal spring maintains constant sealing pressure
  • High-grade construction resists marine oils, saltwater, and hydraulic fluids
  • Cross-references: 888483, 888906, 896600, Sierra 18-0564, GLM 85019

This genuine Quicksilver seal ensures proper fitment and long-lasting performance in demanding marine environments. Two seals are typically required per lower unit gearcase assembly. Regular inspection and replacement of propeller shaft seals during routine maintenance helps prevent costly lower unit damage and maintains optimal engine performance.

During a regular boating season I usually damage one aluminum prop per year . Once again, I needed to replace my prop on a 50hp outboard that I use during fishing and deer hunting on the Missouri River. In past years I have had to allow time for the new prop to arrive. Not this time! The people at Boatplicity got the prop to me the very next day! And I paid the lowest price I have ever paid for the prop. I now have Boatplicity on my favorites list and will definitely use them for all my boating needs.

All was great. I will recommend to customers looking to purchase good quality parts

perfect store ever i shop
