A cracked or sun-warped cowl cap robs your mid-range punch by letting spray and hot air churn around the intake. Swap it for Mercury’s Air Dam Cap 8M0159887 and give your 30-60 HP EFI outboard the smooth, cool airflow it was built for.
Exact OEM fit for 30, 35 Jet, 40, 50, 60 EFI—including the punchy 60R. Replaces 8M0118170 and 879147T12 with zero fuss.
One-piece ABS composite shrugs off UV and dock bumps while weighing just over two pounds—no rattles at idle.
Integrated “M” icon & MERCURY decals arrive factory-installed, so your cowling looks showroom fresh the minute you bolt it down.
Internal vane design channels air across the intake plenum and sheds water before it can reach the filter, keeping temps steady on long river runs.
Installation is a Saturday-morning breeze: four screws off, four screws on, done. You’ll notice quicker hole shots, a quieter growl, and the satisfaction that every wave of cool air is hitting the flame arrestor—not swirling aimlessly under the hood. Small swap, big payoff for your trusty Mercury.
