Deine Fragen / Unsere Antworte

What is the typical mounting diameter for most fan cowls and how do I measure it correctly?
Common diameters range from 60 to 150 mm, with 75 mm and 100 mm being the most frequently installed. Measure the inner diameter of the existing deck opening – not the outer diameter of the old cowl – and compare this with the product specifications.
Does a fan in the engine compartment really need to be explosion-proof?
Yes, if gasoline, diesel, or LPG fumes can occur in the engine compartment, a spark-free, explosion-proof fan is mandatory – this is not a matter of preference, but of onboard safety. Corresponding products are marked as such in the product data.
Can I seal a passive fan cowl watertight when it's stormy?
Many fan cowls can be rotated so that the opening faces leeward, reducing spray entry. Some models also have a plug or flap for complete sealing – check the product details to see if this feature is available.
Which material is the most durable for saltwater use?
UV-stabilized ABS plastic and stainless steel (V4A) are the most reliable materials for saltwater use. Chrome-plated brass looks good initially but corrodes under the layer as soon as it has minor damage.
