Buying Guide for choosing the best marine, freshwater pump:

Well, so far, I have described our best water pump reviews. Yet, when it comes the purchase time, you need to consider some facts for choosing the best boat freshwater pump.

So, considering all the important facts, here, I have provided you with a buying guide that assists you in selecting the best one according to your need and budget.


The first thing you have to consider is the voltage of the water pump. You may face a fresh water pump problem if you don’t select the pump with the right voltage.

Usually, you will find two water pump models with 12-voltage and 24-voltage. And, this voltage choice entirely depends on your water requirement to be pumped out. However, the pumps I have mentioned above all have 12-voltage.

But, if you have a larger-sized boat, you should select a 24-volt fresh water pump that fulfills your heavy-duty applications.

Water flow rate

Another fact that you need to think about before purchase is the water flow rate of the pump. The water pump you will select should have at least 1 GPM water flow rate.

However, the more water flow rates, the more the amount of water demand. So, if you have high demand, you should purchase the water pump having 2-3 GPM or more.

In this case, our SEAFLO Marine and Everflo EF5500-BOX Fresh Water Pumps are an ideal choice for you as both of them provide 5.5 GPM.

You can also choose Jabsco ParMax HD4-12V fresh water pump that provides a 4 GPM water flow rate.

Pressure rating

You also need to look for the pressure rating of the water pump. You will also face boat freshwater pump troubleshooting issues if the pressure rate of the pump is too low. Usually, the pressure rate of the pump ranges from 20 PSI to 60 PSI that depends on the variety of pump models.

However, if you need to operate a small-sized RV or houseboat, you can have a narrow boat fresh water pump with low pressure. And, for heavy-duty applications, you will need high-pressure rates of about 60 PSI like the Jabsco ParMax HD4 fresh water pump.

Is it self-priming or not?

Before buying the water pump, you should also think about its self-priming feature. This feature permits your water pump to lift a sufficient amount of water. It doesn’t matter if your water supply is running low.

And also, the combination of run-drying technology and a self-priming motor prevents damage while the pump is running dry.

Noise and vibration level

You should also look for a water pump that minimizes both noise and also vibrations. Yet, if you have a hurricane deck boat freshwater pump, you may experience a different cracking sound. It is because this fresh water pump easily gets defected on a hurricane boat.

So, you should choose a quiet boat fresh water pump that operates quietly and provides you a disturbance-free performance like Flojet 03526-144A, SHURFLO 4008-101-E65, and Lippert Components fresh water pumps.

Frequently Asked Questions

  • What is a boat motor impeller?

A boat motor impeller is the most significant part of a marine engine. It helps to pump the raw water through engine plumbing from far beyond the boat.

Yet, you should always check your pump impeller if it’s getting worse or not. And also, it should have a quality motor impeller; otherwise, you will experience no water coming out due to having a bad motor impeller.

  • Where is the water pump on an outboard motor?

The water pump on an outboard motor is usually located above the lower gear case assembly. Therefore, this location makes it easier to access as well as offers more convenient services.

  • What are the worst boat brands?

Some of the worst boat brands you should avoid as your watercraft’s plan include Luhr, Kingfisher, Renkin, Bayliner, etc.

The reason for avoiding these brands is they don’t provide you technical service when you need it, and most importantly, they are not durable enough and come of poor quality.

  • How often should you change the water pump on an outboard motor?

Generally, the water pump on an outboard motor lasts well for at least 5-6 years with proper care. However, I recommend you replace the boat freshwater pump impeller with this like every 3 years. Otherwise, you may experience that your pump impeller may wear out.


So, we have reached our final part. In our review list, the Fimco 5151087 Flo High-Performance fresh water pump is the best pick overall. The reason is it offers you incredible power efficiency, super durability, and high reliability with upgraded new features.

You can also choose SEAFLO Marine and SHURFLO 4008-101-E65 fresh water pumps as they are budget-and user-friendly water pumps and deliver energy-efficient and superior performances.
