Is the BOAT ETNA exhaust system hose suitable for continuous operation at +100Â°C and resistant to marine weather and fire?

Yes. The BOAT ETNA exhaust system hose is specified for operation from -30Â°C to +100Â°C and its inner layer is made of CR synthetic rubber resistant to exhaust gases, while the outer corrugated CR layer is fire- and weather-resistant. It is designed for waterâcooled diesel engine exhausts (mixed exhaust gases and cooling water), has vacuum resistance, a burst pressure â¥2 bar, and carries Lloydâs type certification 99/00169 (E4) and VTT homologation to Nordic Boat Standard MC9. Conclusion: Suitable for continuous operation up to +100Â°C and resistant to marine weather and fire as described, when used in the intended shortâsection installations between pipes.

Can the BOAT ETNA exhaust system hose withstand vacuum conditions and maintain integrity under sea spray and UV exposure?

Yes. The BOAT ETNA exhaust system hose is specifically designed for marine exhaust use and can withstand vacuum conditions, as its specification explicitly states it "has vacuum resistance." Its construction - CR (chloroprene) inner layer resistant to exhaust gases, synthetic cord and steel spiral reinforcement, and a corrugated CR outer layer resistant to fire and weather - ensures integrity under sea spray and UV exposure. Itâs also Lloydâs type certified (99/00169 (E4)) and VTT-homologated to Nordic Boat Standard MC9, with operating temperatures of -30Â°C to +100Â°C and burst pressure â¥2 bar, supporting reliable performance in marine environments.

Does the BOAT ETNA exhaust system hose meet Lloyds and VTT certifications for marine diesel engine use?

Yes. The BOAT ETNA exhaust system hose meets both Lloydâs and VTT certifications for marine diesel engine use. It is compliant with Lloydâs type certificate 99/00169 (E4) and homologated by VTT according to the Nordic Boat Standard MC9. The hose is specifically designed for water-cooled exhaust systems of diesel engines in motorboats and yachts, features an inner CR rubber layer resistant to exhaust gases, an outer fire- and weather-resistant CR layer, vacuum resistance, and suitable operating temperatures (â30Â°C to +100Â°C), making it appropriate for short-section exhaust connections handling mixed exhaust gases and cooling water.
