Mercury Extreme Grease – 92-8M0190470 (14 oz cartridge)

Give every hard-working joint on your rig the protection it deserves. This calcium-sulfonate, NLGI 2 grease clings tenaciously to metal, resists wash-out in a following sea, and stays put at engine-room temperatures that make lesser lubes slump. Slide the 14 oz cartridge into any standard gun and feed steering cables, gimbal bearings, U-joints, drive-shaft splines—even trailer wheel hubs—then forget about salt-water pitting or metal-to-metal squeal.

Why boat owners reach for Extreme Grease:

• Tackles heavy shock loads and disc-brake heat while meeting tough GC-LB specs

• Rust-blocking additives guard splines and races during long lay-ups

• Fully compatible with lithium greases—no messy purge required

• Clean blue-green tint makes it easy to spot fresh push-out on zerks

One tube is usually enough for a full annual service on a single-engine rig, with a dab left for the trailer. Pump until that blue bead appears and head back to the water, confident every moving part is primed for another season of wide-open runs and sharp turns.
