Description

Volvo Penta 11998 is a genuine OEM gasket used on Volvo Penta engine and drive applications. Current Volvo Penta parts references continue to list 11998 as an active genuine gasket, while current dealer and parts-market references describe it as a small individual sealing gasket used to maintain a reliable seal and help prevent leaks in the related assembly.

Key Features

• Genuine Volvo Penta OEM part number 11998.
• Individual service gasket, sold separately rather than as a kit.
• Current dealer references show it as a very small, lightweight gasket, with one current listing showing approximate weight around 0.003 kg.
• Built for exact-fit sealing in the covered Volvo Penta application.

Engine Compatibility
Current public references confirm the OEM number clearly, but the most specific reviewed application description currently available identifies 11998 as a temperature sender gasket. One reviewed current listing ties it to Volvo Penta diesel applications including D1-13, D1-20, D1-30, D2-40, D2-50, D2-55, D2-60, D2-75, and KAD32. Because public fitment coverage is limited, fitment should still be confirmed by exact engine serial number and by matching the original sender sealing point before ordering.

Serial Number Fitment Notice
Small sender and sensor gaskets can vary by engine family, sender style, and production range. Confirm Volvo Penta 11998 by engine serial number and by matching the original gasket shape and installation location before ordering. Volvo Penta’s current parts shop continues to list 11998 as an active genuine gasket part number.

When This Part Needs Replacement
Replace this gasket whenever the related temperature sender or sealing component is removed for service, or when the original gasket shows seepage, flattening, hardening, cracking, or visible sealing-surface deterioration. Because current reviewed references identify 11998 as a temperature sender gasket, renewing it during sender service is the right service practice for reliable reassembly.

Installation Notes
Install on clean, flat mating surfaces and compare the new gasket directly to the original before final assembly. Since current public references confirm the part number more clearly than they publish a broad official fitment list, serial-number verification and direct comparison to the removed gasket are the best checkpoints before installation.

Alternate/Superseded Part Numbers
Current reviewed interchange references show 11998 connected with older or alternate numbers including 6604943, 15301, 20542740, and 977935 in replacement-market data. Current confirmed Volvo Penta ordering number is 11998.

Parts Desk Insight
For small sealing parts like 11998, the strongest buying checkpoint is the exact installation location rather than appearance alone. Current reviewed references point most clearly to temperature sender use, so matching the original gasket shape and confirming by engine serial number is the cleanest way to avoid ordering the wrong small sealing part.
