PCM / Crusader R020044 is an OEM crankshaft position sensor for select 6.0L LQ4 marine engines. This sensor provides crankshaft position information to the engine control system so timing and fuel-delivery calculations can be managed correctly. Current marine parts references identify R020044 as a genuine PleasureCraft / Crusader crankshaft sensor for the 6.0L LQ4 application.
Key Features
- OEM-style crankshaft position sensor for select PCM / Crusader 6.0L engines
- Designed for the LQ4 6.0L engine family
- Helps provide crankshaft position data to the ECM
- Commonly cataloged as Sensor, Crankshaft (6.0L)
- Part number: R020044
- Related OEM reference: Crusader R020044
- Replaces Indmar 55-1360 in supported applications
Engine Compatibility
This sensor is listed for PCM / Crusader 6.0L LQ4 engines. Nautique and PCM-focused references note that R020044 applies to the LQ4 6.0L, where the engine model number typically contains 600 — for example, xx-600xx-xx. For later 6.0L LY6 / L96 applications, references distinguish a different sensor, R020054, commonly associated with model numbers containing 601 or 602.
Serial Number Fitment Notice
Fitment should be confirmed by the full engine model and serial number before ordering. This part is best matched by the PCM / Crusader engine model code, especially because R020044 and R020054 are both 6.0L crankshaft sensor references but apply to different GM-based marine engine families.
When This Part Needs Replacement
Replace the crankshaft position sensor if the engine has crank/no-start symptoms, intermittent stalling, poor running caused by loss of crank signal, diagnostic faults related to crankshaft position, or damaged wiring/connector issues at the sensor. The crank sensor is a critical EFI input and should be diagnosed before replacement.
Installation Notes
Confirm the engine is the correct 6.0L LQ4 / 600-series application before installation. Inspect the connector, harness condition, sensor mounting area, and related wiring before replacing the sensor. Clear any stored diagnostic faults after repair and verify proper engine operation.
