Trident Marine 250-6004 Exhaust Hose
When your exhaust system calls for a 6-inch inside diameter hose, you are working with a large inboard engine, a generator, or a commercial marine application where exhaust volume and heat demand heavy-duty hose construction. The Trident Marine 250-6004 is a hardwall exhaust hose with a 6" ID and a 12.5-foot length, built to handle the high-temperature wet exhaust conditions found in demanding marine engine installations.
Hardwall construction means this hose maintains its shape under vacuum and compression without collapsing, which is critical in exhaust routing where bends and long runs can create negative pressure conditions. The 6" inside diameter provides the flow capacity needed for high-output engines where undersized exhaust hose creates back pressure and reduces engine performance. Trident's 250 series exhaust hose is constructed with a wire-reinforced wall for structural integrity and a heat- and oil-resistant inner liner rated for continuous wet exhaust service.
At 12.5 feet, this section covers most single-run exhaust routing needs on larger inboard installations. Trident Marine exhaust hose meets ABYC and USCG standards for marine exhaust applications, making it the appropriate choice for both new builds and replacement work where compliance matters.

$192.38
$244.33
Trident Marine 250-1124 Exhaust Hose
The Trident Marine 250-1124 is a hardwall wet exhaust hose designed for inboard and stern drive marine engines. With a 1-1/2" inner diameter and 12.5 feet of hose, it covers most standard exhaust routing runs and gives you enough length to work around bends, risers, and tight bilge layouts without splicing.
Hardwall construction is the key difference here. Unlike corrugated exhaust hose, the rigid inner wall resists collapsing under suction and holds its shape through the heat and pressure cycles that come with regular engine use. It's built to handle the mix of exhaust gases and cooling water that flows through a wet exhaust system, and it does it without breaking down from the inside out.
Trident Marine manufactures this hose in the USA and it meets USCG Type A2 standards for marine exhaust applications. The 1-1/2" ID is a common size for smaller inboard and stern drive setups, so it fits right in with most factory exhaust configurations. If your current hose is soft, cracked, or showing its age, this is a direct replacement that will hold up through many more seasons on the water.

Trident Marine 110-1144 Exhaust Hose
The Trident Marine 110-1144 is a softwall wet exhaust hose built for inboard and stern drive marine engines. It measures 1-1/4" inner diameter and comes in a 12.5-foot length, giving you enough hose to handle most standard exhaust runs with room to navigate bends and tight bilge spaces.
Softwall construction uses a corrugated inner wall that flexes easily, making it a practical choice for installations where the hose needs to bend around obstacles or follow a non-linear path from the exhaust manifold or riser to the transom. The flexibility also helps absorb engine vibration, which reduces stress on fittings and connections over time.
Like all Trident Marine exhaust hose, the 110-1144 is designed to carry the combined flow of exhaust gases and engine cooling water that runs through a wet exhaust system. It holds up against heat, moisture, and the mild acids that can form in exhaust gas, and it's manufactured in the USA to USCG standards. The 1-1/4" ID fits a range of smaller inboard and stern drive applications where a compact exhaust path is needed.

Trident Marine 110-0784 Exhaust Hose
The Trident Marine 110-0784 is a softwall wet exhaust hose designed for smaller inboard and stern drive marine engines. With a 7/8" inner diameter and 12.5 feet of length, it's sized for compact exhaust systems where a larger hose simply won't fit the routing path or the fittings on the engine.
The corrugated softwall design gives this hose the flexibility to bend and route through tight bilge spaces without kinking. That makes installation considerably easier when you're working around frames, stringers, or other components that stand between the exhaust outlet and the transom. It also does a solid job of absorbing engine vibration, which helps extend the life of the connections at both ends.
Built in the USA by Trident Marine, this hose is rated for wet exhaust service and handles the combination of hot exhaust gases and engine cooling water that flows through the system during normal operation. The 7/8" ID is less common than larger sizes, so if this is the spec your engine calls for, it's worth having the right hose on hand rather than trying to make a larger size work.

Trident Marine 100-1184 Exhaust Hose
The Trident Marine 100-1184 is a hardwall wet exhaust hose designed for inboard and stern drive marine engines running a 1-1/8" exhaust outlet. The 12.5-foot length covers most standard exhaust runs from the riser or manifold to the transom, with enough extra to handle routing around the typical obstacles you find in a bilge.
Hardwall construction means the inner wall is smooth and rigid rather than corrugated. That rigid wall resists collapsing under suction, holds its shape through repeated heat and cool cycles, and keeps exhaust flow unrestricted over the life of the hose. It's the right choice for installations where the hose runs in a relatively straight path and maintaining consistent inner diameter matters for exhaust backpressure.
Like all Trident Marine wet exhaust hose, the 100-1184 is built to carry the combined flow of hot exhaust gases and engine cooling water that runs through the system during normal operation. It's manufactured in the USA to USCG standards and is a direct replacement for worn or deteriorating exhaust hose on engines that spec a 1-1/8" ID outlet.

Trident Marine 110-0344 Exhaust Hose
The Trident Marine 110-0344 is a softwall wet exhaust hose built for smaller inboard and stern drive marine engines that run a 3/4" exhaust outlet. At 12.5 feet long, it gives you a full run of hose to work with, whether you're doing a straightforward replacement or routing through a more involved bilge layout.
The corrugated softwall construction is what makes this hose easy to work with. It bends without kinking, which is a real advantage when you're threading hose around frames, fuel tanks, or other components that get in the way of a clean exhaust path. The flexibility also helps the hose absorb engine vibration rather than transferring it directly to the fittings, which keeps connections tight and leak-free over time.
This hose is rated for wet exhaust service, meaning it's designed to carry the mix of hot exhaust gases and engine cooling water that flows through the system while the engine is running. Trident Marine builds it in the USA to USCG standards, and the 3/4" ID makes it a match for smaller outboard-style inboard engines and compact stern drive setups where a larger hose would be overkill.
