Good To Know

Q: Will this oil pressure sender work on my MerCruiser 4.3L? A: This sender is compatible with many MerCruiser models, but we recommend checking your engine serial number to confirm fitment.

Q: What is the difference between a sender and a switch? A: A sender sends a variable signal to a gauge, while a switch triggers a warning light; this unit functions as both.
