WEN PW31 3100 Pressure Washer

WEN PW31 3100 PSI: My Favorite Pressure Washer for Boats

If you own a boat, then you know one of the most tedious tasks that you have to perform after every boating adventure, and that is to give the hull a good cleaning.  That is why I strongly recommend the WEN PW31 3100 PSI Gas Pressure Washer, 208 cc. It’s one of those tools that every boater needs to thoroughly give their boat that deep clean it needs, quickly and painlessly.

This little unit packs a whopping 3100 PSI, so you know it means business. Most pressure washers designed for residential use typically have a PSI range from 2000 to 2900, making this 3100 PSI stand out in a league of its own. And let me be honest, it’s also a lot of fun to use while making sure every knock and cranny gets washed.

The WEN PW31 3100 PSI is powered by a 208 CC OHV 4-stroke engine with a single-cylinder design with forced air cooling.

In this review I am going to go over everything in-depth about why I love the WEN PW31 3100 PSI, and why you will too when you are done reading this.

Product Features:

First, we should take a look at the most notable features and specs the WEN PW31 3100 PSI has to offer. I’ll also touch more on these features and specs later throughout this review.

  • Packing a very powerful 208 cc 4-stroke OHV engine
  • Blasts 2.5 gallons of water per minute
  • It comes with five quick-connect nozzles to conquer light, medium or heavy-duty cleaning, with onboard storage making it quick easy to switch the nozzles as needed

What Can it Wash?

The better question, should be, what can’t this bad boy wash? As mentioned, the WEN PW31 3100 PSI comes with five different quick-connect spray nozzles to tackle all sorts of various projects. This power washer is the ideal choice for all types of vehicles, such as cars, SUV’s, ATV’s, Boats, RV’s, as well as Home siding and brickwork, Driveways, Decks and so on.

Each quick-connect nozzle is designed to conquer specific tasks with a blast radius ranging from (0º, 15º, 25º, 40º and soap).

  • 0º – is used to get at high and hard to reach areas; cleans crevices in sidewalks or on driveways
  • 15º – is used to tackle stubborn stains on hard surfaces such as concrete, and brick
  • 25º – This tip is used on painted surfaces, fences, wooden siding, boat hulls, lawn mowers, and boat propellers
  • 40º – Use this tip on windows and screens
  • Soap – Used when you want to spray soaps and detergents

Size, Weight, and Portability

WEN PW31 3100 PSI Gas Pressure WasherFor a pressure washer, that’s this well build, the WEN PW31 3100 PSI  comes in weighing 67 pounds. The size of the product itself is only 21 x 21 x 40 inches, making it easy to store or transport in the back of a truck or the trunk of a car.

If you’ve ever owned a pressure washer before, then you know how frustrating it can be when your hose gets kinked due to improper storage. With onboard storage space for your pressurized hose, you can store and protect the 30-foot high-pressure hose.

Because the WEN PW31 3100 PSI is a gas pressured washer, you don’t have the restrictions of a corded pressure washer, allowing you the freedom to move around with ease.

12 inch wheelsThe nice big 12 inch wheels on the back of the unit make it simple to move from point A to point B. The wheels don’t get caught up easily on small rocks or pebbles, a problem I’ve had with other pressure washers I’ve owned in the past. In fact, I was using this pressure washer at my brother-in-law’s house, and he has a gravel driveway. While dragging the unit behind me, it seemed to roll over the rocks with ease.

Pros and Cons

Let’s a closer look at the WEN PW31 3100 PSI pros and cons:

 Pros

  • It’s a mighty little unit and very easy to use
  • No power cord to worry about
  • 30-foot high-pressure hose (not the average 25-feet they usually come with)
  • Comes with five nozzles and has onboard storage slots for each one
  • It’s not as noisy as some other gas-powered pressure washers I’ve seen
  • The handle collapses for easy storage
  • The unit stands solid and doesn’t shake around while in use
  • Big solid 12-inch tires to move through all kinds of different terrains
  • Great price, with a decent warranty

Cons

  • There is no way to adjust the PSI
  • When the unit is running the nozzle heads, tend to bounce around and sometimes bunch out of their holder
  • There is no automatic choke
  • Strict maintenance schedule and tedious cleanup after each use

Why is it important to clean the bottom of your boat?

Keeping the bottom of your boat clean is important because a dirty hull can cause many different maintenance problems as well as allow the boat to glide much more smoothly in the water. Washing after each use will help prevent rust and salt corrosion on any metal surfaces. Having a clean boat will also improve fuel efficiency.
