If so how hard/easy are they to use? Boat will fit in gargae and I think the G Jacks will help but not sure where to get them and if they even work on tandem trailers.

I think RedRanger uses them in his storage

Mark,

A couple of years back I used to post photos of my ZX250 in a 19x19 garage due to using gojacks. My 120 lb wife could push the boat in circles once I had them installed. They'll make moving a tandem axle trailer as easy as a single once they are installed.

I initially bought 4 of them as they were sold in pairs and I didn't catch that. I sold 2 of them off and only used one pair on the front tires. It was still easy to maneuver. They are easy to get on and off and I felt they were well worth the money. I would probably add that the smoother finished the concrete floor is the easier they'll be to use.

If you're wanting to push the boat sideways you'll need 4. If you only want to twist it 2 will work.

I would use google and find the cheapest online source for them.

best thing there every was. Been using mine for two years, I got two sets, total of four. The are the bomb baby.

let me know if you need any more info.

I have them as well. one handed pushing involved. easy use you only need 2 of them though.

I use the harbor freight version. They are about 75 each. Just put them on the front tires only and then push the front over. I taped off lines on the floor to stop and now it takes about 5 minutes to unhook get it

I bought a Ranger Z21 in January and had to put it in a swing drive garage. I bought 4 of them from harbor freight so I could back in about half way in the garage then unhook it and move it pretty much wherever I wanted to put it. Once I got the boat in place I would lower the jacks back to the ground to keep the boat from moving. If it wasn't for the swing tongue it would have never fit into my garage.
Since then I have moved to a house that has a 30x30 shop so they are now collecting dust...
They were definitely a back saver when I needed them.

If you are interested in selling them let me know. Thanks

Those look alot easier then what I have been doing...I also have a J swing garage and could not get my boat where it needed to be. I bought 4 car dollies(which worked) but it was a pain taking a jack to each tire lifting sliding the dolly into place letting the jack down and repeating 3 more times. Once in place I could push it anywhere I wanted to...these look like they would have made the task much easier...

They are worth every penny. Have had a pair for 5 yrs and can't imagine trying to park the boat in the garage without them.

PM sent.

Okie Poke uses them.

Hey Mark.....they are a breeze to use. I have to swing my boat around once its backed in to the garage. I have a pair but only use 1 on the front tire on one side because it pushes very easily to where I need it to go with only one on. Let me know if you wanna come over and see how mine work, well worth the money for me. 972-571-7513
