Frequently Asked Questions
- Is this vent made of real 316 stainless steel or just a 304 alloy with a polish?
- This vent is strictly engineered from AISI 316 marine-grade stainless steel. Unlike 304, 316 contains molybdenum which provides critical resistance to chlorides (salt), making it the only choice for long-term exposure to saltwater without pitting or surface rust.
- Does the adjustable knob stay in place under high engine vibration?
- Yes. The center butterfly mechanism uses a tension-riveted pivot points that provide enough friction to hold your desired setting securely, even during rough water transit or high-RPM engine operation.
- What is the exact cutout diameter needed for the 5-inch model?
- The 5-inch model (125mm overall diameter) requires a standard 4-inch (101mm) cutout. This allows for the flange to sit flush against the mounting surface while providing a secure seal.
