Parts Desk Insights
The 22734346 is the upper transmission section of the IPS10-A drive — it is not a conventional sterndrive upper unit and should not be compared to or substituted with upper gear assemblies from other IPS drive sizes. The most reliable identification point is the IPS10-A drive designation, where this part pairs with lower gear 22734347 inside the complete 22734345 assembly. Customers occasionally inquire about this part when the complete drive unit (22734345) is the more practical solution for a full drive replacement — if you’re unsure whether you need the upper gear alone or the complete assembly, contact us before ordering.
