RINA-Approved Exhaust Hoses: Why They're Essential

Exhaust hoses for marine engines aren't all created equal. A non-specific hose, perhaps one from a car, will melt after just a few hours in the engine room. Our RINA-approved hoses are designed to withstand the high temperatures of exhaust gases and the corrosive saltwater environment. Don't risk a fire or carbon monoxide poisoning. A functioning boat discharge system relies on quality hoses.

Choosing the correct diameter is crucial. A hose that's too narrow causes back pressure and engine overheating. A hose that's too wide reduces the effectiveness of water cooling. Always check your engine specifications and choose the hose with the appropriate mm measurements.

Materials and Durability: What to Check

Even if not specified by the manufacturer, visually inspect the hose condition every year. Look for cracks, bulges, or discolored areas. If the hose is rigid or has fissures, replace it immediately. A good condition exhaust hose ensures the safety and efficiency of your engine. Consider the role of the boat scupper alongside the exhaust system for overall vessel health.

Another aspect not to be underestimated is the mm bending radius. Avoid tight bends that can obstruct the flow of exhaust gases and cause engine problems. Use 45 or 90 degree fittings for more gradual curves.

Can I use this hose for my water-cooled muffler?

It depends on the model of your muffler and the engine specifications. Check the inside diameter of the muffler fitting and compare it to the outside diameter of the hose. If you have any doubts, contact us with the model of the engine and muffler: we will recommend the most suitable hose.

How often should I replace the exhaust hoses?

The lifespan depends on the engine's hours of use and environmental conditions. In general, it is advisable to replace the exhaust hoses every 5-7 years, or sooner if signs of wear are noticed. An annual visual inspection is essential to prevent problems.

Which type of hose is most resistant to temperature?

RINA-approved hoses are made of specific materials to withstand the high temperatures of exhaust gases. Always verify that the hose is certified for marine use and that it is suitable for the maximum operating temperature of your engine.
