Installing the boat washdown pump is not a simple process, and sufficient preparations are required for installation. If you want to install the washdown pump smoothly, you need to handle the water supply and the pump.

If you already have seawater (or raw water) pipelines on your ship, you can use it to supply water to the washdown pump. Therefore, in addition to the pump itself, you also need hoses and clamps to install it.

If your ship does not have sea water pipelines, you need to install a straight-through hull, sea c and filter to provide a flushing system as well as the washdown pump itself.

Before installing the washdown pump, we must first clean the fish intestines, weeds, dirt and other debris taken away from the boat. The easiest way is to install the washdown and be ready.

Step 1. Choose an accessible location to install the pump, keeping the length of plumbing pipes and electrical wires to a minimum. Most pumps need to be installed in areas that stay dry.

Step 2. Mount the pump to a sturdy part of the boat such as a bulkhead, using a rubber insulator between the pump and the boat to reduce vibration and noise passing from the pump to the boat.

Step 3. For a boat with an existing seawater line, add a T-connector or Y-connector into that line to supply the washdown pump without having to install another thru-hull. If there’s no existing seawater line, install a new thru-hull fitting complete with a seacock shut-off valve to supply the washdown pump.

PRO TIP: Don’t use the inboard’s raw-water intake line, as the washdown pump may steal too much of the motor’s cooling water. Only use a marine-grade hose with a higher PSI rating than the washdown pump’s capability.

Step 4. If the washdown pump is below deck, install a washdown outlet plate through the deck, and run the pump’s outlet hose to the underside of the outlet plate.
