The Genuine Tohatsu 3B7-60217-1 Trim Tab Anode is designed for selected 60HP–140HP 2-stroke and TLDI outboard motors. Manufactured from sacrificial anode metal, it helps protect underwater engine components against galvanic corrosion while allowing trim tab adjustment to reduce propeller steering torque. Ideal for replacing worn, corroded or damaged trim tabs, this genuine replacement component supports reliable steering performance and long-term outboard maintenance.

Signs the Trim Tab Anode Needs Replacing

  • - Excessive Corrosion: Anode has deteriorated significantly through normal sacrificial action.
  • - Material Loss: Approximately half or more of the original anode material has been consumed.
  • - Broken or Damaged Fin: Trim tab is cracked, bent or missing.
  • - Poor Steering Balance: Increased steering effort or pulling to one side that cannot be corrected through normal adjustment.
  • - Loose Mounting: Trim tab no longer remains securely attached.
  • - Uneven Deterioration: Deep pitting or severe corrosion affects the anode's structural integrity.
  • - Physical Damage: Impact with debris or underwater obstacles has damaged the trim tab.
  • - Scheduled Maintenance: Inspection identifies insufficient remaining material for continued corrosion protection.

Important Fitment Information

  • - Confirm the engine model, serial number and original trim tab part number before ordering.
  • - This part suits selected conventional 2-stroke and TLDI outboards; it is not a universal 60HP–140HP trim tab.
  • - The correct trim tab depends on the gearcase configuration.
  • - Check the mounting hole, anode profile and clearance around the propeller.
  • - Inspect the 3B7-60219-0 trim tab packing during replacement.
  • - Record the original trim tab angle before removal to preserve the initial steering adjustment.
  • - Adjust the trim tab according to the manufacturer's instructions after installation.
  • - Do not paint the sacrificial anode, as coating it can interfere with corrosion protection.
  • - Ensure the mounting surface provides the required electrical contact.
