Volvo Penta 181620 is a genuine OEM sealing ring used in Volvo Penta sterndrive and marine engine service. Volvo Penta’s official parts shop continues to list 181620 as an active genuine sealing ring, and current reviewed public references describe it as an oil seal used in outdrive and engine sealing applications. Current reviewed dimensional references are mixed: some current market listings show 32 x 42 x 4 mm, while others show 35 x 42 x 4 mm, so the safest approach is to verify the original installed seal and serial-number-based application before ordering.
Key Features
- Genuine Volvo Penta OEM part number 181620.
- Identified in current reviewed sources as a sealing ring / oil seal.
- Current reviewed public dimensions are reported as 32 x 42 x 4 mm in one source and 35 x 42 x 4 mm in another, so direct application confirmation is important.
- Current reviewed aftermarket interchange references associate this seal with Sierra 18-2057 and GLM 87070.
Engine Compatibility
Current public references point more clearly to drive compatibility than to one narrow engine-only list. The strongest reviewed fitment references associate Volvo Penta 181620 with older sterndrive families including SX, DP, and DPX, with one current listing describing coverage for 1983–1998 SX, DP, and DPX drives across 4-cylinder, 6-cylinder, and V8 applications. Another reviewed schematic reference places 181620 in DP-A2 / marine propulsion and notes it as included in repair kit 876265 for astern lever. Fitment should still be confirmed by exact drive model and serial number before ordering.
Serial Number Fitment Notice
Sealing rings can vary by shaft size, housing bore, lip design, and production range. Confirm Volvo Penta 181620 by engine or drive serial number and by matching the original seal location and dimensions before ordering. Because current reviewed public dimension listings conflict, serial-number verification and direct comparison to the removed seal are the safest checkpoints.
When This Part Needs Replacement
Replace this sealing ring when the original shows oil leakage, hardening, cracking, wear on the sealing lip, or damage found during engine or outdrive service. Current reviewed public sources describe 181620 as an oil seal used to help keep lubricant in place while protecting shafts and bearings from dirt and contamination, which makes replacement appropriate whenever sealing performance is compromised.
Installation Notes
Match the replacement directly to the original before installation and inspect the shaft and housing surfaces during service. Since current public references confirm the part number and general seal function more clearly than they publish a single reliable dimensional standard, direct comparison to the removed part and serial-number confirmation are the safest checkpoints before final assembly.
Alternate/Superseded Part Numbers
Current reviewed aftermarket-equivalent references associate Volvo Penta 181620 with Sierra 18-2057, GLM 87070, and EMP 26-01462 in the same seal family. Some current market listings also use the alternate Volvo format 181620-6. Current confirmed OEM ordering number remains 181620.
Parts Desk Insight
For a part like 181620, the strongest buying checkpoint is the exact seal location and drive family, not the word “sealing ring” alone. Current reviewed sources point to older Volvo Penta sterndrive use, especially SX / DP / DPX applications, but the mixed public dimension data means the cleanest way to avoid ordering the wrong seal is to match the original part and confirm by serial number.
