Engine Compatibility
This plug is intended for Mercury or Quicksilver propellers with PVS vent holes rather than for one specific engine family. The clearest fitment wording ties it to Mercury and Quicksilver propellers using the PVS system, with one source specifically noting an exception for large tube Trophy applications.
Serial Number Fitment Notice
Please confirm fitment by propeller model, engine model, and serial number before ordering. Matching the current propeller’s vent-hole setup is the safest approach, especially when tuning PVS plugs by hole size.
When This Part Needs Replacement
Replace the vent plug when the original plug is missing, damaged, loose, cracked, or no longer holding proper fit in the propeller vent port. It is also commonly replaced when changing vent-hole size as part of propeller performance tuning. This guidance follows the part’s role as a removable PVS tuning plug.
Installation Notes
Install only in compatible PVS-equipped propellers and confirm the hole size needed for the application. Medium-hole plugs like 889725T35 are commonly used when dialing in holeshot and load response, and they should be matched to the propeller and boat setup rather than chosen by engine alone.

Parts Desk Insight
This is the medium PVS plug, which makes it a tuning part as much as a replacement part. It is a good choice when the propeller already uses the Mercury/Quicksilver PVS system and the goal is to match or fine-tune venting with the medium .350 in / 9 mm plug size.
