Parts Desk Insights
Best use case: Ideal for technicians and DIY boaters performing lower-unit or vertical shaft service on a DP-SM Duo-Prop drive. This is a precision needle roller bushing — sourcing it as a genuine OEM part ensures correct fit in the shaft and housing bore.
Common questions: Customers sometimes order by part type rather than by serial number and diagram position. Needle roller bushings can appear nearly identical while differing in bore diameter, width, or cage design. Match the part number directly from the Volvo Penta parts diagram for your serial-numbered drive, and physically compare the replacement to the removed bushing before installation.
