Inboard Exhaust Outlets: Quality and Durability

Inboard exhaust outlets are a critical component of your inboard engine's exhaust system. Their function is to channel exhaust gases away from the hull, ensuring safe and efficient engine operation. A damaged or inefficient exhaust outlet can cause overheating, gas leaks, and even engine damage.

At Nautica Basile, you'll find inboard exhaust outlets, crafted from high-quality materials such as AISI 316 stainless steel and high-temperature resistant rubber. Available in various shapes and sizes (diameters from 40 to 90 mm) to fit any type of boat and engine. We offer straight, 45°, and 90° fittings for easy installation, even in tight spaces.

A common problem is corrosion due to exposure to saltwater. AISI 316 stainless steel offers superior corrosion resistance compared to other materials, ensuring greater durability. Regularly inspect your inboard discharge outlets for any signs of corrosion or damage and replace them promptly to avoid more serious problems. Replacing your inboard exhaust pipe before failure is key to keeping your boat running smoothly.

Frequently Asked Questions

What is the correct exhaust outlet diameter for my engine?

The correct exhaust outlet diameter depends on the engine's horsepower and the diameter of the exhaust manifold. Consult your engine manual or a qualified mechanic to determine the correct diameter. An insufficient diameter can cause back pressure and overheating, while an excessive diameter can reduce engine efficiency.

How can I prevent corrosion of the exhaust outlets?

To prevent corrosion, use only exhaust outlets made of corrosion-resistant materials such as AISI 316 stainless steel. Regularly apply an anti-corrosion protectant and clean the exhaust outlets with fresh water after each use in saltwater. Periodically check the condition of the hose clamps.

Can I use a rubber exhaust outlet for my inboard engine?

Yes, rubber exhaust outlets are suitable for inboard engines, provided they are made of rubber that is resistant to high temperatures and exhaust gases. Verify that the rubber is certified for marine use and that it is compatible with the type of fuel used by your engine (gasoline or diesel).
