⚠️ Important – This is NOT the Trim Switch
Please note:
35340-ZZ5-D21 = TROLLING CONTROL SWITCH
It is different from:
35370-ZZ5-D02 = POWER TRIM / TILT SWITCH
Although the switches are fitted in similar remote-control assemblies, they perform different functions.
Important – Check Before Ordering
Not every Honda engine within the HP range has the trolling control function.
Please check:
Exact engine model
Engine serial number
Remote control box
Original switch part number
Wiring and connector
Trolling control function
Do not order by horsepower or appearance alone.
If unsure, send us your engine model, serial number and a photo of your existing switch/connector and we will check compatibility.
