Function
The sender kit mounts on the transom assembly and monitors the trim position of the sterndrive. It sends this information to the boat’s trim gauge and limits trim travel to protect the drive when operating at speed.
This helps provide:
-
Accurate trim gauge readings
-
Proper drive trim control
-
Protection from over-trimming at high speeds
The kit includes the trim position sender, trim limit switch, and wiring leads for a complete replacement.
Symptoms of a Faulty Trim Sender
A failing trim sender may cause:
-
Trim gauge stuck or inaccurate
-
Erratic trim readings
-
Trim limit function not working properly
Replacing the sender kit restores proper trim position feedback and trim control.
⚠️ Fitment Tip:
Always verify compatibility using the sterndrive model and serial number. This kit is designed for analog trim gauge systems and is not compatible with SmartCraft digital systems
