Give your Verado the tight seal it was born with by swapping in Mercury’s 27-8M0033641 OEM gasket. Cut from fuel-resistant fiber composite and formed to the exact gear-housing profile of 350 SCi models, this thin ring does the quiet work of keeping gear lube in and saltwater out—mile after mile, trim after trim.

Why this little circle matters

• Exact factory geometry hugs the driveshaft carrier so there’s no trimming, stretching, or RTV guesswork.

• Multi-layer fiber/graphite blend shrugs off 300 °F oil temps and the shearing force of heavy‐weight gear lube.

• Uniform 3 mm crush zone delivers even torque across the flange, stopping seepage that can milkshake your lower unit.

• One-piece design drops in during routine service; no fiddly inserts or alignment tabs to lose in the bilge.

Practical payoff? Cleaner lube checks, steadier oil pressures, and peace of mind when you hammer the throttle out of the hole. Tuck a spare in your toolkit—because a fifteen-minute gasket change today can save a full gearcase rebuild tomorrow.
