Product Function
The Throttle Position Sensor (TPS) monitors the position of the throttle and sends this information to the ECU / engine management system.
A faulty TPS may contribute to:
-
Poor throttle response
-
Hesitation during acceleration
-
Rough or unstable running
-
Incorrect idle
-
Engine warning / fault indication
-
Reduced engine performance
These symptoms can also be caused by other fuel, air, ignition, wiring or sensor faults, so correct diagnosis is recommended before replacing the sensor.

⚠️ Important Compatibility Warning
Please do not order this sensor by appearance or horsepower alone.
This listing is for selected Mercury / Mariner 115 HP EFI 4-stroke engines using 880884T.
Before ordering, please check:
-
Engine horsepower
-
Complete serial number
-
Original sensor part number
-
Electrical connector
The safest compatibility check is that your engine specifies:
Mercury 880884T
or the corresponding Yamaha 68V-85885-00 sensor family.
If the part looks the same as yours, this does not always mean it is the correct part for your outboard.
If unsure, send SSI Marine your engine horsepower + complete serial number and we will help check compatibility.
Buyer Responsibility
It is the buyer's responsibility to confirm compatibility before purchasing.
OEM part numbers are used for identification and reference purposes only.
Correct diagnosis is recommended before replacing a throttle position sensor, as similar symptoms can be caused by throttle-body adjustment, wiring, ECU, fuel-system or other sensor faults.
