🔌 Function

The trim sender reports sterndrive trim position to the dashboard gauge, while the trim limit switch controls normal upward trim travel. Replacing the kit helps restore accurate gauge indication, correct trim limit operation and reliable trim system feedback.

Common signs of failure:

• Trim gauge stuck fully up or fully down

• Trim gauge reading incorrectly or intermittently

• Trim limit not stopping upward trim travel

• Trim sender wiring damaged at the gimbal ring

• Water-damaged or corroded sender housings

• Trim reading changes while steering

• Sender kit damaged during bellows or transom service
