Industrial 805130A2 Tilt Trim Limit Sender Switch Kit

Industrial 805130A2 Tilt Trim Limit Sender Switch Kit is an aftermarket MerCruiser tilt/trim limit sensor kit designed to replace the tilt/trim sender components on MerCruiser R, MR, Alpha One, and Alpha One Gen II stern drives. The kit is commonly listed with part numbers 805130A2 and 805320A03, and some catalog listings also reference 805129A3, indicating a bundle that covers the trim sender switch together with the associated limit/transmitter parts used in MerCruiser Alpha One/Alpha One Gen II systems. The 805130A2 assembly functions as the tilt/trim limit sender in legacy analog trim circuits, providing the signal that monitors the drive’s tilt range and communicates with the trim system to prevent over-travel. This aftermarket kit is intended as a replacement for worn or failed trim sender components and is associated with MerCruiser Alpha One, Alpha One Gen II, MR, and R drives; compatibility details can vary by exact drive configuration and wiring harness, so verify your model year and wiring before ordering. The kit is sold by multiple retailers as an aftermarket MerCruiser replacement, and may be offered together with related components such as 805320A03 and 805129A3 in some listings, reflecting the common MerCruiser trim sender ecosystem for older stern-drive installations.
