Serial Number Fitment Notice

Confirm the complete drive and transom shield model before ordering. Part number 3860365 is specific to XDP/XXP-style transom shields and should not be selected by comparing its appearance with rubber collars used in SX or DPS assemblies. The safest fitment check is the correct XDP transom shield breakdown and item position, not the part name alone.

When This Part Needs Replacement

Replace the rubber collar when it is:

• Cracked, split, or permanently compressed
• Hardened or deteriorated from age
• Swollen or distorted by oil or grease contamination
• Damaged during gimbal bearing removal
• Loose or unable to seat correctly in the transom shield

The collar should also be inspected whenever the gimbal bearing, bearing seal, or U-joint bellows is serviced.

Installation Notes

Installation requires access to the transom shield bearing area. Clean the collar seat and inspect the adjoining components before installing:

• 184860 Gimbal Bearing
• 3862067 Bearing Plate
• 3861006 Retaining Ring

Parts Desk Insight

This collar is often overlooked because its a small rubber component with a generic-sounding name some catalogs call it a rubber collar, others a rubber element. Both refer to the same 3860365. Since its already accessible during gimbal bearing service, replacing a hardened or damaged collar at the same time avoids a repeat transom shield disassembly. Water or corrosion in the gimbal area is a strong signal to also inspect the U-joint bellows, bearing seal, and retaining ring while everything is apart.
