SEACHOICE Exhaust Guard Covers for 4 in. OD Pipe — Black Rubber with Stainless Steel Clamps, Pack of 2

When a boat slows or stops, backflow and wave action can force water into exhaust outlets and potentially reach engines or bilges. These Seachoice exhaust guard covers are made from weather-resistant rubber and include adjustable stainless-steel hose clamps to fit 4 inch outer diameter exhaust pipes. Sold as a pair, they provide a straightforward barrier that installs quickly and resists corrosion in marine environments.

How do these exhaust covers reduce water ingress?

The molded rubber flapper creates a flexible seal that closes under backflow pressure, limiting the volume of water that can enter the exhaust through the thru-hull. The clamp secures the cover to the pipe so the flapper stays aligned and effective during light surges and idle conditions.

• Flexible rubber flapper conforms to pipe shape to block incoming water.
• Stainless-steel hose clamp tightens the cover for a consistent seal.
• Designed specifically for 4 inch outer diameter exhaust pipes for proper fit.

Will these fit my boat's exhaust pipe and resist corrosion?

These covers are sized for exhaust pipes with a 4 inch outer diameter, and each unit includes a stainless-steel hose clamp that resists rust common in marine settings. The rubber compound is weather-resistant to handle sun, spray and temperature swings, but periodic inspection is advised for long-term reliability.

• Fits 4 in. OD exhaust pipe—measure your pipe before ordering.
• Stainless steel clamps offer enhanced corrosion resistance compared with plated clamps.
• Weather-resistant rubber reduces degradation from UV and salt spray.

How easy is installation and maintenance?

Installation is a simple one-person task: slip the rubber cover over the exhaust outlet and tighten the included hose clamp to secure its position. Maintenance requires only occasional rinsing and inspection for tears or loose clamps; replace the cover if the rubber shows cracking or the clamp corrodes.

• Quick slip-on installation—no specialized tools required beyond a screwdriver or nut driver.
• Pack of two covers lets you protect twin exhausts or keep a spare on board.
• Inspect periodically and clean with fresh water to extend service life.

Who is this for: These Seachoice exhaust guard covers suit recreational boat owners, anglers, and small-craft operators who want an affordable, easy-to-install way to reduce exhaust backflow when idling or navigating confined waters. Ideal for boats with 4 in. OD exhaust pipes, they provide a practical OEM-style accessory or replacement part for routine maintenance and seasonal preparation.
