Important – UP / DOWN Relay

Some Tohatsu power trim systems use separate UP and DOWN relays.

Please check the relay being replaced and compare:

Original Tohatsu part number
Wire configuration
Electrical terminals
Connector arrangement
Mounting arrangement

before ordering.

Important – Check Before Ordering

Do NOT order this relay by horsepower or appearance alone.

Tohatsu used different trim relay arrangements depending on the engine model and production period.

Before purchasing, please check:

Engine horsepower
Full Tohatsu model
2-Stroke / TLDI
Model year
Engine serial number
Original relay part number
Electrical connections
Wiring configuration

If the relay looks the same as yours, this does not always mean it is the correct relay for your outboard.

Common Symptoms of a Faulty Trim Relay

A faulty power trim relay may cause:

Trim motor not operating
Trim working UP but not DOWN
Trim working DOWN but not UP
Intermittent trim operation
Relay clicking but trim motor not operating
Trim motor operating only occasionally

These symptoms can also be caused by other electrical or hydraulic faults.

Before replacing the relay, we recommend checking:

Battery condition
Battery voltage
Battery terminals
Earth / ground connections
Trim motor
Trim switches
Wiring
Electrical connectors

Important – Electrical Part

Electrical components should be correctly diagnosed before ordering.

Electrical parts that have been fitted or installed cannot be returned unless faulty.

If you are unsure whether the relay is causing the fault, we recommend testing the power trim & tilt electrical system before replacing components.

Buyer Responsibility

It is the buyer's responsibility to confirm compatibility with the engine model and serial number before purchase.

If you are unsure, contact SSI Marine with your:

Engine model
Serial number
Existing relay part number

and our technical team will be happy to help confirm compatibility.
