Parts Desk Insights
This is the correct choice for late-model Volvo Penta SX stern drives where both the trim motor and reservoir have failed or are leaking — replacing the complete assembly saves time and ensures both components are fresh. The coarse-thread designation is critical: confirm your SX drive uses coarse-thread hydraulic fittings before ordering, as fine-thread SX models require a different unit. If only the motor needs replacement and the reservoir is still serviceable, see the ARCO 57-6233 Tilt/Trim Motor for Volvo Penta SX (without reservoir). For trim system electrical components, see the ARCO Trim Relay Assembly for Volvo Penta (57-R767), the ARCO Relay for Volvo Penta (57-R809), or the Volvo Penta Power Trim Relay 854357. If the hydraulic pump itself has failed, see the Volvo Penta Trim Pump 21945915.
