Marco DP3 Deck Wash Pump Kit: A Compact Marine Wash Down Pump That's Always Ready
If you're looking for a reliable marine deck wash pump for washing down your deck, hull, or onboard gear, the Marco DP3 12V/24V deck washing pump kit (3 bar) deserves your attention — a self-priming electric wash down pump engineered specifically for boat and marine wash down applications.
What This Pump Is
The DP3 belongs to Marco's Electronic Deck Washing Pumps line and comes as a complete 12V/24V boat wash down kit with a 15 m (50 ft) lay-flat hose. Key specifications:
Voltage: 12V or 24V DC (part numbers 164 800 12 / 164 800 13)
Flow rate: 14 l/min (3.7 gpm)
Maximum pressure: 3 bar (43.5 psi) — a true high pressure deck wash pump
Current draw: 10 A, 15 A fuse, 150 W motor
Weight: 4.6 kg complete with reel and hose — a genuinely compact deck wash pump
Ports: 3/8" BSPP, hose inner diameter 13 mm
Protection class: IP44
Gun jet range: up to 7.5 m at 3 bar outlet pressure
The pump is self-priming: its working elements are PTFE gears capable of running dry for short periods without damage — critical for marine pumps, where a momentary lack of water in the system is not uncommon.
The DP3's Competitive Edge
Simplicity and compactness. The DP3 is the lightest and most accessible model in the lineup. Where extreme pressure isn't required and compactness, low power consumption, and reliability matter most, the DP3 is the optimal deck wash pump for small boats and yachts.
Universal 12V/24V power. One pump suits both standard and 24-volt onboard electrical systems — no need to pick a separate model for your vessel's marine electrical system.
A complete out-of-the-box kit. The package includes a 15 m lay-flat hose with a DQC quick-release coupling, a wash down gun with Aqua-stop function (shutting off the flow right at the gun), and an air bleed valve for easy priming on first start-up.
Proven, durable design. The PTFE gears tolerate brief dry running, the kit includes rubber anti-vibration mounts (reducing noise and vibration), and a built-in 0.5 mm strainer on the suction side protects the pump from clogging.
Low-cost maintenance. The motor's average brush life is around 2,500 hours under normal operation, and the warranty is 2 years from the date of purchase.
Electrical safety. The pump comes with an EMI filter and a mandatory fuse (warranty is void without one) — solid protection against overloads and short circuits.
Bottom line: the DP3 balances price, weight, and functionality for anyone who wants a boat deck washing system that works straight out of the box without excessive power.
What If You Need More Pressure?
Marco's Electronic Deck Washing Pumps 12V/24V-DC line offers three more marine wash down pump kit options that logically build on the DP3 as pressure requirements grow:
Model | Flow | Pressure | Motor | Weight | Highlight |
DP3/E | 14 l/min | 3 bar (43.5 psi) | 150 W | 4.6 kg | Entry model, a great start |
DP9/E | 12 l/min | 4.5 bar (65.3 psi) | 180 W | 4.6 kg | High Pressure |
DP10/E-MS | 18 l/min | 8 bar (116 psi) | 320 W | 5.5 kg | NEW, mechanical seal, High Pressure |
DP12/E | 15 l/min | 6 bar (87 psi) | 360 W | 5.5 kg | High Pressure |
All models come in the same format — a pump kit with hose and gun and DQC coupling — so upgrading to a more powerful model doesn't change your onboard installation layout.
DP9/E — a step up in pressure (4.5 bar) at the same weight as the DP3 — when you need a stronger jet without a serious size increase.
DP10/E-MS — the new flagship with the highest pressure (8 bar) and a mechanical seal instead of the standard one — for the most demanding washing tasks on larger vessels.
DP12/E — the middle option at 6 bar for those who find the DP9 insufficient but the DP10 overkill.
Conclusion
The Marco DP3 deck wash pump kit is a dependable entry point into the deck wash pump lineup: lightweight, simple, supplied with a ready hose-and-gun kit, dual 12/24V voltage, and Marco's proven self-priming PTFE gear technology. And as your needs grow, the full Marco range (DP9, DP10/E-MS, DP12/E) lets you move up to higher pressure without changing your system concept.
