Excellent Corrosion Resistance

The simple truth is that salt can be highly corrosive to metal when exposure lasts for an extended period of time. So, the more you tow around it, the more you need to protect your trailer from it. The Z-Max zinc finish on this jack offers great corrosion protection, even with occasional use around saltwater.


Rust-resistant coatings are graded according to a salt spray rating. Basically, this rating shows the amount of time it takes for a material to show signs of corrosion when exposed to pure, continuous salt spray. Traditional zinc plating typically begins to deteriorate after about 100 hours. Dacromet usually lasts for around 300 to 400 hours. Fulton's Z-Max finish lasts for 600 hours in the salt spray test - 30% longer than a standard powder coat finish.


The environment this test creates is much harsher than anything you'll ever experience in your journeys, but it provides a testament to how well this jack resists rust and corrosion.


How to Determine the Lift Capacity You Need in a Jack

A trailer jack lifts your trailer high enough at the tongue to allow you to couple it with your vehicle. Usually, your tongue weight is about 10-15% of your gross trailer weight (GTW). For example, a 10,000-lb trailer has a tongue weight of 1,000 lbs to 1,500 lbs. To raise the tongue of a trailer this size, you'd need a jack that can handle a static load of no less than 1,500 lbs. And, yes, it's okay to have a jack with a weight rating that is higher than your trailer's tongue weight. In fact, a jack with a higher capacity should operate more efficiently, allowing you to spend less time cranking and more time fishing.

This product has proven durable and easy to use. Installation with simple and straight forward. If you're looking for a robustly built, long lasting Jack for your boat this would be THE product you're looking for. We previously purchased other jacks that did not last, became hard to crank, and ultimately failed. I'm glad I purchased this.

This Jack Still functions smoothly and is easy to use.



by:

VERY WELL MADE, WORTH THE EXTRA $. GREASE FITTING IS GOOD WAY TO SERVICE AND EXTEND JACK LIFE. REPLACED A 27 YEAR OLD BASIC FULTON THAT FAILED.



by:

Very heavy duty jack!!! Replaced a topwind a-frame jack with this one so I wouldn’t have to worry about any dents in my tailgate. I mounted in-wards so you can still raise/lower the Jack from the drivers side. etrailer got this to me in 2 days, great company!!!



by:

Had a Fulton marine jack on my trailer but the yard where I keep it moved trailers without properly raising the jack. Destroyed the crank mechanism and bracket. Purchased this heavier duty jack (boat is 4,500 lbs) and it installed easily and works smoothly. Quick shipment from etrailer.

The product is exactly what I needed for my trailer. Also, the service/communication with etrailer was excellent. I emailed about the shipping state and got numerous emails back with that information plus much more.

I currently have the Fulton 3500 lb capacity Magnum Series trailer jack. Would the 5,000 cap jack replace my jack? The trailer is 3 x 4 where the current jack is mounted.Also, are there any additional items I need to purchase to mount the new jack?Thanks for any info!Billy

The Fulton Marine Jack, part HD50000101, comes with three sets of U-bolts to fit different trailer frame sizes. Obviously it is not an exact replacement, the difference in weight capacity, but it will fit a 3x4 inch trailer frame. The U-bolts are designed to fit, 4, 5 and 6 inch tall frames, so you will need the smallest set.

Excellent product. I pull a trailer every day. This jack is absolutely great.

I bought new tires and galvanized rims for my snow mobile trailer and boat trailer.
After one year I am still happy with my purchase. I also bought the Fulton 5K marine jack
And love it. I haven't had any trouble at all with tires, rims, or Jack.
Service was great too!

by:

this jack is heavy duty and has a good outside coating that should last for years. I have it mounted on a trailer with the top of the draw bar around 19" off the ground . If the trailer has a low draw bar you may need to mount this higher for ground clearance. Great product ,very strong , easy to crank up loaded and the quick drop foot is much faster then cranking .



by:

I bought this jack last year to supplement my jack with the wheel on it. To get my boat in the garage I have to use a 3 inch drop and since the driveway slopes downward I only have about 8 inches of clearance to the ground. This jack lets me get the boat all the way in the garage AND can still get the trailer on and off the hitch.



by:

I received the package this afternoon and installed it on my boat trailer. I have a heavy aluminum river boat with some t-1 plate on the bottom. I needed a jack stand that was stable when the boat is on the trailer. This product works well and I will be recommending it to my fellow guides here on the Salmon River here in Idaho.



by:

There is nothing wrong with the jack itself. Very easy to lift the trailer tong and really smooth compare to old jack. I would give it 5 stars. However I could not mount it because U-bolts provided are about 1/2" short. And it is OK too, things happen. The problem is there is no any information whatsoever about mounting dimensions or bolt sizes and specifications. For that matter installation instructions enclosed are for the different type of jack.See attached photos. Now I have to play guessing games is it 7/16" diameter or else? Is it 4" or 4 1/16" wide, what kind of thread? In other words instead of what would be a simple procedure for tightening 4 nuts I need to spend time and more money to finish installation. In fact back in April I asked these questions and never got any clear and Intelligence answer from etrailer "experts". Why is it difficult to provide this information?



by:

This jack is heavy duty and was easy to install. I have a saltwater boat that we trailer to and from the bay each time we go fishing and the salt is tough on gear. So far the unit has lasted a full year without significant rust accumulation or malfunction. 2 years seems to be the typical life of most components, however, so next year will be the test.



by:

Product as advertised, very sturdy and easy to mount to trailer with all the different U-bolts supplied with the jack. You Just have to pick the best U-bolt out of the box, when mounting to your trailer. I would purchase this product again.



by:

Quality product. Built extremely solid, excellent welds, smooth crank, mounting plate holes are deberred, in fact I could not find a burr anywhere. I purchased 2 of these for a project and found they have great adjustability. The mounting "U" bolts supplied are for 3 different size trailer tongues and are 1/2" dia. These lifts certainly appear to be able to handle their 5000# rating.
Etrailer shipped the order the next day. The product was well protected, Three layers of cardboard. The order arrived in excellent condition.



by:

This is the second time I have bought this.
The
first time was for my 20’ snow mobile trailer.
It has performed flawlessly for the last 4 years.

So it was time to buy a new jack for my boat trailer.
20’ Mako center console. It’s an over kill, but it is rock solid and know problem lifting the hitch
Up to get on a lifted Ram 1500

Highly recommend

great communication, arrived on time. Most other vendors out of stock

I call etrailer At 800-298-8924 & got my order taken by a real Person that was Customer Friendly. I received My order in a timely manner also.

It also was a excellent Price.

  • Is 5,000 lb Fulton Marine Jack Easier to Use Than 2,500 lb Fulton Marine Jack
    That's a really good question, and the answer is yes, the 5,000 lb capacity Fulton Marine Jack # HD50000101 will be easier to jack up than the 2,500 lb etrailer Marine Jack # MJSQ-2500B. The gears are in fact different, with the smaller 2,500 capacity jack having gears that are both smaller in diameter and less teeth. So while both of these jacks are high-quality with good salt spray rating, and fit trailer frames up to 3" wide x 5" tall, if you are looking for the jack that is going to...

    While your frustration is understandable and we have a solution for you, I wouldn't be able to tell you with absolute certainty that using the Stromberg Carlson Electric Trailer Jack # JET-3755 will stop your tailgate from hitting the jack.

  • Trailer Jack Recommendations for a 10,000 Pound A-Frame Trailer
    A trailer jack only lifts part of the weight of the trailer and not the whole 10,000 pounds of your trailer. A 10K trailer would have a tongue weight of around 1,000 to 1,500 pounds. But the higher the capacity of the jack the easier it is for the jack to lift the weight and the longer it will last. A jack rated for 5,000 pounds such as # TJA-5000S-B is an option. You could add foot # JF-99 as well. I have linked a video review of the jack for you. If you'd prefer an electric jack then...

  • Bolt-On Side-Wind Frame-Mount Trailer Jack With Handle Facing Driver-Side of Trailer
    On A-frame side-wind tongue jacks like the 5K-rated etrailer # TJA-5000S-B the mounting hole pattern is not symmetrical so the jack has to mount in just one orientation. This means the handle facing forward. You might consider a side-of-frame-mounted jack like those shown on the linked page. Most of these are weld-on installs but we do have a bolt-on model, part # HD50000101 from Fulton. This 5K jack includes a foot plate, a drop-leg feature and provides 14-inches of lift.
