A New Exhaust Temperature Sensor Group Is Used on Certain 3500 Marine Engines {1919, 7498}
- Engine:
- 3512 (S/N: 50Y1-UP)
- 3512B (S/N: S2H1-UP; S2J1-UP; S2L1-UP; S2M1-UP; 7HM1-UP; 8EM1-UP; 4TN1-UP; 2EZ1-UP)
- 3512C (S/N: TTC1-UP; TTF1-UP; TTG1-UP; MKH1-UP; E3W1-UP; E3Y1-UP)
- 3516 (S/N: 3XS1-UP)
- 3516B (S/N: 8CN1-UP; 8KN1-UP; 9AN1-UP; S2R1-UP; S2S1-UP; 4BW1-UP; S2X1-UP; S2Y1-UP)
- 3516C (S/N: TTD1-UP; PAG1-UP; TTH1-UP; TTJ1-UP; JTS1-UP)
Description of Change: The new temperature sensor groups utilize gold plated pins. The gold plating has a higher resistance to wear than the typical nickel plating.
Adaptable To: The new 449-3985 Temperature Sensor Gp replaces the existing 243-5752 Temperature Sensor Gp. The new temperature sensor group is adaptable back to first production on the serial numbers listed above.
Note: When the new 449-3985 Temperature Sensor Gp is installed, also install new 9X-3402 Connector Sockets in the factory wiring harness connectors.This change is effective for the serial numbers listed in Table 1.
