We recently acquired the inventory of a large marine parts distributor that went out of business. This is a new old stock item in excellent condition with the factory original packaging.

We were able to determine this is a Sierra 18-4391 Gasket Set based on the part number located on the factory original packaging.

This Gasket Set is a direct replacement for Mercruiser 27-64763A2.

Interchangeable with:

•  GLM
  • 39680

Includes 18-3883 Head Gasket

This Gasket Set is designed for Ford (S/N 4173000-4500860) 351 CID 233 HP 5.8L Inboard Motors. Also Fits Mercruiser, OMC, and Volvo Penta 351 CID/5.8L Inboard Motors.

Please see photos for more regarding the condition and please verify compatibility before purchasing. This item is guaranteed non-DOA, however, because it is a new old stock item it does not carry any manufacturer’s warranty. Sierra 18-4391 Gasket Set.
