The Diesel Pro Difference

Since we opened our doors over fifteen years ago, we have had the pleasure of serving many satisfied customers. Most of these customers had a focus on ocean-going vessels, from sailboats and yachts, to fishing boats and barges. Regardless of the whether it was used for pleasure or for business, our customers knew the necessity of having parts that not only performed their job flawlessly, but also kept working after many hours of use.

Our pumps are built to work long-term. We build them to exacting standards, ensuring that what you receive is a high quality sea water pump that will last, even under the toughest of circumstances. As an added bonus, our distributor direct pricing means that you get a brand-new pump for the price of a refurbished one.

Raw Water Pumps vs. Sea Water Pumps

What we refer to as the sea water pump is also commonly known as a raw water pump, and there is no difference between how they function. These pumps perform a vital role on the craft, keeping the engine cool by taking in the raw water from the surrounding environment through the seacock. This water is drawn into the engine room and usually through a strainer to keep foreign materials out.

Marine Water Pumps and Fresh Water Pumps

Many engines make use of a fresh water pump in addition to a marine water pump. If there is any doubt as to whether you need a fresh water pump versus a sea water pump, check the connections leading to the pump. The fresh water pump is completely contained within the engine system, where a sea water pump will have to have to have access to the outside of the boats hull through the seacock.

If you are unsure which pump type you need, give us a call and our friendly staff will help you get the right part for your project, and get your boat back on the water quickly.
