Today we'll going to be taking a look at a round swivel marine jack with an included wheel. This marine jack is going to let you raise and lower your boat, or recreational trailer. It's going to have a lift capacity of 1200 pounds and its going to feature a swivel design. That way you can swing the jack up a long your trailer frame for storage, or you can bring it back down when you're ready to use it. It's going to feature a 4-bolt mounting option. That's going to provide extra side load support, your mounting hardware, and the brackets to get this bolted onto the frame of your trailer, as well as the mounting plate. That's all included.
Now, real quick, I just want to show that swivel design. It's a really neat feature and it's really easy to use. So the way that it works, is you're going to have this 1/2 inch convenient spring-loaded pull pin. This is going to be disengaged in order to rotate the jack either up or down. this plate is going to mount on one side of your trailer frame. The brackets are going to mount on the other side of your trailer frame.
So your frame is going to be in between and those 2 components are going to be held together with the included bolts and lock nuts. If this is fixed or mounted to your trailer frame, you can pull the pin and you can see how the mounting plate and the jack move independently from one another. There's going to be 4 holes that that pin can be engaged in. So you can really have the jack situated how you want along your trailer frame. It's a really nice design and again just that option to be able to move that up to a stowed position when it's not being used or when you're in travel, is a really great benefit. The jack also comes with the plastic wheel.
This is included and this is going to be welded to the bottom of the inner tube. Now, the wheel itself is actually bolted to the wheel mount, and then the wheel mount is welded to the bottom of the inner tube. I do want to mention that this wheel, it does spin around, but since it is attached to the bottom of the inner tube that inner tube is going to spin along with it. But it's still a nice design. It's going to give you the maneuverability that you need, especially when trying to get your trailer into some of those tough areas.
This is going to allow you to really change the angle and get it to where you need it. It's a really nice design. Right here you're going to have a really nice fluid, side-wind handle. It's got a nice comfortable grip. It's got a textured grip, so you can easily get a good grip on it when you're raising and lowering the jack. That's going to give us a handle radius measuring from the center of where it mounts to the outer edge of the hand grip of 6 5/8 of an inch. Now, the components of the jack, the main components, the outer tube, inner tube, mount right here for the wheel, and for the trailer, that's going to be steel construction. As well as the pull pin. There's a lot of steel on here. Now to make sure that it doesn't rust and corrode what they've done is they've put a really nice corrosion resistant clear zinc finish on it. This is going to be ideal for marine applications. Another measurement I want to mention is going to be our bracket height. With the jack as low as it'll go, fully retracted, I took a measurement from the bottom of the wheel to the center of the bracket and that measured 12 1/2 inches. I did that same measurement with the jack fully extended and that increased it to 23 1/2 inches. This jack is going to give us a travel or a lift of 11 inches. The outer tube is going to give us a diameter of 2 inches. The inner tube is going to give us a diameter of 1 3/4 of an inch. The wheel, that's going to give us a diameter of 5 3/4 of an inch. It's going to give us a width measurement, outside edge to outside edge of right at 2 inches wide. Now, that's a really nice thick plastic construction. It's going to last a long time. You can see that it's not a spoke design, so that's solid all the way through. Really a lot of support, and it's got the support braces in there as well. The wheel is going to be a strong, and durable design. hen it comes to the mounting bracket, this is going to give us an overall length measurement of 6 7/8 of an inch. Overall height measurement, that's going to give us a measurement of 5 3/4 of an inch. The distance between the mount holes going across looks to be pretty close to 5 1/2 inches, and then going up and down, from the center of this hole to the center of this hole, we're looking at 2 7/16 of an inch. Center of this hole to the center of that middle hole, that's going to be 3 7/16 of an inch. Center of this hole to the center of that outer hole is going to be 4 7/16 of an inch. And again your brackets and your hardware is included for and easier bolt on installation of this round swivel marine jack. That's going to complete today's look at the round swivel marine jack with a lift capacity of 1200 pounds.

Great product, i would by another one. Thanks 506561
Work great for me, you should advertise that it may fit your Old jack mounting plate, (welded on) just remove your bracket, and fits Mine with a, c clamp. 575753
Bought and installed on my 4’x8’ trailer. Basically bought do I didn’t have to pick up my trailer and pull it around to move it because of my bad back. Trailer jack is larger than I thought it would be but it was ok, worked out great. I like the large wheel, now I can push it around and unhook if the trailer is still loaded. Great purchase. Recommended product 578552
These are working so much better than the support legs that came with my pop-up. I mounted two on the back bumper and have one on the tongue, I can level my trailor upon set-up in minutes, or can jack the trailor and change a tire in minutes..... Great Product Wonderful Price.... 571968
I bought this swivel jack for a utility trailer. It appears very well made and works well. Excellent value. 370342
Have used it for a year. Still like new!
Dave L - 04/21/2018Had a hard time finding a trailer jack for my boat. It was unique and did not what to place jack in a different place on the trailer frame. I sent in photos of what I had. Within in a day I had a response with the correct jack and they shipped it that day. Got it 2 days later installed at the lake today, it works perfect. These guys and gals know there stuff. Excellent customer service!!! 441796
Jack is working great. Make about 30 trips to the lake this year. Great product!!
Craig B - 10/11/2018I purchased my Mj-1200B trailer jack last year for my DJ equipment trailer. The quality is great and more heavy duty than I probably need for a small 4x6' trailer but I couldn't be without it. No issues what so ever and so I'm very happy with the purchase! 370515
Prompt delivery as expected. Product seems a cut above the previous one from them (that I trashed jack-knifing while reversing) even though the price was the same. 287543
Several positive items come to mind. First, I was impressed with the extensive alternative items available - it almost made the choice difficult - too much variety in what was available. But a lot of information and reviews helped with selection. In the end price and ratings were most helpful.There was a wide range of prices and I choose the least expensive but it seems to be well constructed and plenty adequate for the job. Second, I wasn't expecting but enjoyed that after ordering my shipping was upgraded. I had ordered Sunday and the item was delivered Wednesday. And in a box that had handles so it was easy to move around. And packed in recyclable materials. Attaching the swivel trailer jack was simple and easy and required no instructions. Only took 15 minutes and most of that time was finding my tools. I haven't used it yet but it should work fine. And now I'll be able to move my trailer and kayaks much more easily. 579206
Very nice! Very easy to install. I never thought it would be so easy to reposition my boat in the garage. Moves so smoothly raising/lowering my trailer on/off my hitch. My only wish is that I would have replaced my old jack sooner! I highly recommend this wheel jack... 548415
Product didn't fit but that's on me. Nothing wrong with the product or etrailer's description just me not paying attention enough. 648040
I've been very happy with this purchase. It's much sturdier than the unit I replaced it with which was appreciated. It has held up well over the year I've had it and expect many more years of effortless service. 647606
The trailer jack arrived quickly and as expected from previous experience was of great quality It was easy to install and works great 644347
Good service and fast delivery 640424
This is the second time I've purchased this product and it rusts before the boating season is over. It is the only part of my trailer that rusts so it must be the part. 634143
This Jack is the perfect fit for any trailer and makes it so much easier to move around on smooth surfaces. 617951
Excellent serves from E-Trailer! and the product was just as described. 605460
The jack works great, a year later still works like the day I put it on. I installed it on my snowmobile trailer, gets exposed to salt and road crap, no problems at all. Etrailer is a great place to deal with, always amazed by how fast they ship!! 5 Stars!! 595832

Great jack, working pretty well. It's nice to be able to swing it out of the way. Broke a wheel, but Etrailer had a replacement. 582839
Have not used product yet. I'm sure it will meet my expectations 582645

Quality product and works great. 571278
Perfect for my canoe trailer 564497
Works great, the crank is very smooth Plus George upgraded the shipping!! 553852
All items look great, everything came on time, I have not installed any thing yet, and very good pricing! Thanks again! 550905
Took a bit of wrangling to get the jack on the trailer tongue, but only b/c I didn't have another set of hands to help. It took me ~20 min to put it on. I realize now that my trailer is back heavy, I need to attach a scissors jack to help it remain stable. Even so the wheel allows me to maneuver it around and already a great addition. 549840
Extremely satisfied with this product and the delivery service that was provided. I highly recommend etrailer Corporation. 514511
Product was received proptly and works as advertised 499174
Package somehow got routed wrong by UPS, but got here anyway. All product in great shape. I woulld suggest new bolts with the hitch couplers when shipping. Having to go looking for bolts on a Sunday or late at night is a pain in the butt. But great products nonetheless! 494135
Everything looks good so far just opened the boxes. 481613
Installation information was not great, but the Mj-1200B is a sturdy jack. 477530

Very well made and easy to install. Great price! Fully recommend the product and etrailer.com. 465447
Great price and works perfect! 451091
My boat trailer jack arrived promptly, well packaged, and complete. It is a heavy duty jack with a rotating bottom wheel assembly at a cost less than other stores which is lighter weight and does not rotate.. Excellent attaching hardware. 449529
Excellent quality products for a very reasonable price and extremely fast shipping and delivery!!! 442731

Replaces a worn out jack on my near antique boat and trailer. Very happy with the quality and ease of operation. 440371
Easy to install. Works as advertised. 424001
Very well made, easy to install. I really love the product videos. They are a big help in choosing the right product. I stopped even looking anyplace else. I've learned etrailer.com alway has the best product at the best price. And the service is great. 417281
I'm impressed - it's a very sturdy piece of equipment, and feels much higher quality than the price suggests. Much easier to use than the one it replaced, and the fold-up function is very handy. 407255
I've had this tongue jack for about a year now. There's VERY little sign of rust after being exposed to the salt air and the jack still works as new. What killed the last one was the lock pin for the swivel action was not holding properly. The swivel plates, lock pin and lock pin spring are still in excellent shape on this unit. 405721
Fast delivery time! Will order from here again. 401056
A year later and I still love it. Makes it very easy to move my trailer around.
Eric B - 07/02/2018I attached this to my Casita Trailer and removed the factory installed one so that I could use my tailgate without hitting it on the hitch. Worked like a dream and was able to install with ease in 5 minutes. 399516
Still very happy. I wish the wheel was detachable and a foot could be installed. Sometimes the wheel is a bit too tall for unhooking from my Tacoma.
