Description
SIERRA Mercury O-Ring – 18-7961 is a large-diameter replacement O-ring for specified Mercury marine applications. Its 92.7 mm (3.650 in) inside diameter and 3.4 mm (0.135 in) cross-section allow the seal to be positively identified by measurement as well as OEM number.
The O-ring replaces Mercury 25-47254. Because large marine O-rings can be similar in appearance but differ enough to leak when substituted, the removed seal and OEM number should be checked before installation.
