Buying Guide

We’re almost towards the end of all that we’ve gathered for the best saltwater washdown pump. But, we can’t let you go without telling you which factors to look out for when looking for the perfect saltwater washdown device.

You should keep these points in mind to ensure you get the washdown pump you want –

High PSI

The higher the water pressure, the better. Not only does a high water pressure allow you to cover wide areas in a short time, but it also swiftly removes the stubborn grit and grime.

Unless you want to spend hours on deck trying to get rid of pesky dirt, we recommend picking a pump with a PSI rating of at least 60.


Although this may not seem like a big deal, it will save you from a bunch of headaches. A loud water pump can be a pain to work with because of its constant ruckus and the risk of noise complaints from neighbors or passersby.

To avoid a stressful cleaning routine, opt for a pump that makes little to no noise.

Durability and Protection

When you’re working with water, it’s crucial you have a pump that’s resistant against water damage. Thermal and ignition protection are common among all water pumps. What you should give more importance to is its rust resistance, and protection against oil and water damage.

Also keep a look out for pumps that have automated features such as auto-shut-off during overheating or self-priming. These are especially good for beginners and first-time users.


Checking the warranty is almost always overlooked. Since you’re getting a device, you should check the warranty of the product before purchase to ensure you can return it if you encounter a problem. This is especially important with water pumps as faulty ones can cause serious accidents.


Q: What is a saltwater washdown pump, and why do I need one?

A: A saltwater washdown pump is a specialized water pump designed for marine applications. It’s used to draw in saltwater and spray it for cleaning purposes on boats, docks, or other marine equipment. You need one to efficiently remove salt, dirt, and grime from your boat, fishing gear, or other marine equipment, ensuring their longevity and performance.

Q: Are electric or manual saltwater washdown pumps better?

A: The choice between electric and manual saltwater washdown pumps depends on your specific needs. Electric pumps are more convenient and provide consistent water flow, making them suitable for frequent use. Manual pumps are simpler and cost-effective but require physical effort to operate. Choose the one that aligns with your usage and vessel size.

Q: What is the ideal flow rate for a saltwater washdown pump?

A: The ideal flow rate depends on your boat’s size and intended use. For smaller boats, a flow rate of around 3-5 gallons per minute (GPM) may suffice. Larger vessels or those used for heavy-duty cleaning may require pumps with a higher flow rate, typically in the range of 5-10 GPM or more.

Q: How can I maintain and prolong the life of my saltwater washdown pump?

A: To maintain your saltwater washdown pump, regularly rinse it with fresh water after use to remove salt residue. Check for any signs of corrosion or damage and replace worn-out parts promptly. It’s also a good practice to install a strainer or filter to prevent debris from entering the pump, causing damage.

Q: Can I use a freshwater washdown pump for saltwater applications?

A: It’s not advisable to use a freshwater washdown pump for saltwater applications due to the risk of corrosion. Saltwater is highly corrosive, and using a pump not designed for it can lead to premature pump failure and potential damage to your boat’s plumbing system. Always choose a pump explicitly designed for saltwater use.

Q: Can I use a saltwater washdown pump for other purposes, like firefighting or emergency dewatering?

A: Some saltwater washdown pumps may have the capacity for emergency dewatering or firefighting, but it’s essential to check the pump’s specifications and ensure it meets the requirements for those applications. Dedicated firefighting or dewatering pumps are typically designed with specific features and capabilities.


To conclude, the best saltwater washdown pump is the one that’s best suited for your boat’s needs as well as your handling capability. If you’re new to water pumps, we highly suggest going for one with the most protection. As for experienced boaters, a professional, marine-grade pump will do the trick.
