Frequently Asked Questions
What is the primary function of a water shutter?
A water shutter's primary function is to prevent water from entering the engine's cooling intake when the vessel is stationary or moving at very low speeds, thereby preventing engine overheating.
How does this shutter prevent overheating?
It creates a seal over the water intake, stopping water ingress. This forces the engine to rely on internal cooling systems or requires the operator to manually manage water flow.
What is the material construction of this water shutter?
The DOMETIC Merc-R Water Shutter is constructed from robust nylon, ensuring durability and resistance to marine conditions.
What type of engine intake system is this shutter designed for?
This specific model is designed for engines that utilize a single water intake for their cooling system.
When should this water shutter be used?
It should be used when the boat is not actively moving at a speed sufficient to draw in adequate cooling water, such as during trailering, docking, or at idle speeds in shallow water.
