Description

Mercury MerCruiser Quicksilver 822777Q1 is a genuine OEM aluminum trim tab anode kit designed for corrosion protection and steering trim function on compatible Mercury, Mariner, and MerCruiser applications. Mercury describes this part as an aluminum trim tab anode for setups requiring extra clearance for high-rake propellers. It helps protect the gearcase from galvanic corrosion while also providing hydrodynamic trim force to aid steering control.

Key Features

• Genuine Mercury MerCruiser Quicksilver OEM part number 822777Q1.
• Aluminum trim tab anode kit for corrosion protection.
• Designed for applications needing extra clearance for high-rake propellers.
• Fits most Mercury/Mariner outboards 35 HP and above, Force 90/120 HP from 1995 and newer, and all Mercury MerCruiser drives per current product references.
• Mercury states the anode should be inspected annually and is easy to replace with hardware included.

Engine Compatibility
Current Mercury and dealer references identify 822777Q1 for most Mercury/Mariner outboards 35 HP and above, 1995-up Force 90 HP and 120 HP outboards, and all Mercury MerCruiser sterndrives/drives. This is best treated as a gearcase/drive-specific trim tab anode, especially where propeller clearance is important for high-rake prop setups.

Serial Number Fitment Notice
Trim tab anodes can vary by gearcase style, drive family, and propeller-clearance requirements. Always confirm 822777Q1 against the exact Mercury or MerCruiser application before ordering, especially if the unit is using a high-rake propeller or an offset/extra-clearance trim tab style.

When This Part Needs Replacement
Replace this anode when it is significantly consumed, pitted, loose, damaged, or no longer providing reliable corrosion protection. Mercury’s product guidance recommends periodic inspection, and current dealer references note visible corrosion and pitting as signs it is time for replacement.

Installation Notes
Install only on the correct matched Mercury or MerCruiser application. This trim tab style is intended for setups needing added propeller clearance, so matching the correct anode shape matters. Make sure the mounting surface is clean and the hardware is properly secured so the anode can make good contact and protect the gearcase as intended. The included-hardware detail and high-rake-propeller clearance purpose are confirmed by current product references; the clean-contact point is standard service practice for anodes.

Alternate/Superseded Part Numbers
Current parts references associate 822777Q1 with earlier or related numbers including 822777A4, 822777A1, 8227772, and 822777, and one current seller reference shows it superseded to 97-822777T1. Cross-reference use should always be verified to the exact application before ordering.

Parts Desk Insight
This style of trim tab anode is a good choice when propeller clearance matters. On boats running higher-rake props, the correct extra-clearance trim tab helps avoid interference while still giving you the corrosion protection and steering-aid function the original setup was designed around.
