Protect your marine engine and pumps from damage with this compact brass water filter. Installed inline on a 20 mm (3/4") hose, this strainer acts as a first line of defense against debris in your raw water or recirculating systems. The housing is made of brass, a material known for its robustness and resistance to corrosion in both fresh and saltwater environments. Despite its sturdy construction, the filter is small – about 55 mm in height and width – making it easy to fit into tight quarters, such as an engine compartment or behind a pump.
Inside the brass body is a fine mesh filter element that catches particulate matter. If you’re drawing water from a lake, river, or the sea (for cooling, live wells, washdown pumps, etc.), that water can carry sand, mud, vegetation, and other impurities. Without a filter, these can clog pump impellers, foul heat exchangers, or cause wear over time. By installing this filter, you ensure that only clean water reaches your equipment. The mesh is dense enough to trap tiny particles but allows sufficient flow for engine cooling or pumping needs.
Maintenance is straightforward: the filter has a removable cap (or bowl) that allows you to take out the mesh screen for cleaning. It’s advisable to check and rinse the filter regularly – for example, after running in shallow, muddy water or at least every few outings – to keep the water flowing freely. The brass cap seals tightly, often with an O-ring, to prevent leaks while in operation. Given its small size, servicing it is quick and doesn't require special tools beyond basic hand tools to open the cap.
- Engine cooling intake: Install this filter on your inboard or sterndrive engine’s raw water intake line. It will catch sand or shells that could otherwise block cooling passages, thereby preventing overheating.
- Livewell or baitwell pump: A must-have for fishing boats, placed before the livewell pump. It stops bait scales, weeds, or other debris from jamming the pump and keeps water circulated to your live bait clean.
- Deck washdown system: When using an onboard washdown pump drawing seawater, this strainer protects the pump from grit and debris, prolonging its life and ensuring strong water pressure for cleaning decks or gear.
- Compact water systems: On small boats or RIBs with limited space, this filter’s tiny footprint means you can still have filtration even if your installation area is confined. It can tuck away along a hose run without getting in the way.
A compact brass water filter like this is an inexpensive insurance policy for your boat’s vital systems. By filtering the water before it reaches sensitive components, you reduce maintenance costs and avoid downtime caused by clogs or damage. Built from quality brass and designed for ease of use, this filter will be a reliable part of your boat’s plumbing. Pair it with quality hoses and clamps during installation, and you’ll have a robust setup that keeps your engine and pumps running smoothly.
