View Full Version : Installing a boat lift

I picked up a used boat lift this winter and am getting ready to install it next to my dock. I've got what I think is a good plan to assemble it on the shore with and arrangement of 4 55 gallon plastic drums, rope and 4 come-alongs to allow me to float it in place and lower it to the bottom. My question is if anyone knows of a website or source that gives any best practices or suggested ways of doing this so I can give myself a sanity check.

Any advice or experience in this would be greatly appreciated. The lift is an older aluminum cable/cantilever type with a 110v motor.

Thanks!

Sounds like a lot of work, I pay my pier guy $50 to put mine in and take it out each year with his pontoon fork truck rig...no worry's or sanity checks needed.....

how far out are you going? how's the lake bottom? How deep? you would be surprised at what a couple cheap air tubes can do! You just let the air out when its in place and it sinks to the bottom.

Sounds nice!!! No such animal on my lake, I wish there was.

I'm just going from my shore, out about 30' to get around my dock and am setting it in about 5' of water. The bottom is fairly rocky. I'm guessing I'll need to get a friend that dives to go down and shore up the feet and pile rocks on top of them to make it all sturdy.

As someone mentioned above, a couple of well inflated inner tubes work great. One thing to keep in mind is that the the corner with the 110V motor and gearbox will be considerably heavier than any other, so be sure to place extra bouyancy around this corner to avoid tipping (been there, done that and it's not fun.)
Also, if you can get your hands on 4 pieces of heavy pipe, about 4 feet in length, you can usually slide these into each corner section and use them to lit the rig...much easier than finding a place on the aluminum to lift.

I have a Shore Station boat lift and just tie ropes to the outer two legs down by the base and use the ole Mastercraft to drag it into place. Just a little above idle moves mine with no problem. Once you have it in generally the right place you might need to jump in the water with some buddies and fine tune it's position. Not that big of a deal to move.

When ever boat hoist comes up I have copied and pasted web sites and I am not sure if that subject ever comes up in them but feel free to check!!!

But then you can always fill a couple of coolers full of beer and invite a bunch of buddys to the lake for a hoist launching party and muscle it in!!!

I've taken out and put in shore stations forever (30 years), and have tried all kinds of different methods. In my "expert" opinion have found one guy on each corner, with the guy who claims to be the strongest or drunkest on the corner with the wheel. Once in place, haul some serious ***, and don't stop until in position. This is important because the aluminum lift -the wheel is relatively light with the weight disbursed. They get extremely heavy when they fill full with water.

On our small lake we have a group of friends with four boat lifts. Each site is a little different so we need to employ different techniques. One site we lower it into the water on planks secured with a winch. Another we float with a floating dock under the cradle using hand winch or ratchet strap to pull up lift frame. When we need to move them a long distance on land we put long forks on a skid steer and pick them up. We find 5 strong people is the minimum to move a 4k capacity lift without canopy. I use a HiLift when adjusting the legs on my lift.

When I bought my current lift I had to transport it a long way to a suitable site for removal, so we put an aluminum boat under the cradle cracked up the frame and drove away. http://jamiecarroll.com/waterski/lift_move_04/Boat_lift.pdf The seller was amazed so he took the pics.

heck get the wheel kit and a hi lift jack, lift it up put the wheels in. push it out, hilift pull wheels.

Bring hilift on shore, spray down with air comp. mist w/ WD and put it in the crawl space till fall.

What i ment to say, is this the kind of lift you are looking for or a hand crank lift?

Ummm, probably not. Guess again.

The lift is an older aluminum cable/cantilever type with a 110v motor.

Also, what part of your boat did you design?

2000 Mastercraft Prostar that I designed

Thanks everyone for all the great input and pictures!

randyb,

I'm just reinforcing the use of tubes instead of messing with barrels and straps. Two old tractor tire tubes is all you need. I have a very steep and rocky bank, so getting it to the water is the hard part, but since I started using tubes it's down to a two man operation using various means of mechanical advantage and old highway guard rails. I do have a friend that lives on a gently sloped sandy bank and he does it by himself.

I've also done the long distance transport on top of a flatbottom boat and hauling on a snowmobile trailer for on the road transports.

Wheel kit.

In spring, you roll it in and take the wheels off.

In fall, put the wheels back on, have a couple of people sand on the back of it as counterbalance as you use a truck or four-wheeler with a tow-strap to pull it out.

All good advice this, but it's still a lot of hard work from between 4-6 individuals. One tip, make sure that any moving parts are 'locked' so that innocent hands don't get trapped in heavy moving parts! Best of British!

How do you normally attach the tractor tubes to the lift?

sethro

No attaching involved. When the lift is in the water, simply set the deflated tube in/under the framework somewhere and inflate with air. Then when the lift starts to float, move it where you want it, and then deflate the tube enough to get it out from underneath the frame.

On my cantilever lift, I'm putting the tube right under a cross brace below the main frame. My water depth is uniform, meaning when I get it in the water along shore it is the depth at which it will be sitting in the place I want it. No gradual shore slope and varying water depths for me.

If your shore has a gradual slope, simply drag it the approximate depth it will be sitting in and find a spot to insert and inflate the tubes to raise it slightly off the bottom and move it around your dock and into place.

Got it! Sounds much simpler that what I was thinking of! Thank you.

Here is another one. We used a forklift once we got it put togeter to sit in in the water and then took a jon boat and pushed it around into my slip.

Nice lift. HydroHoists like that one don't squeak.

That looks like a pretty narrow slip.

easy there.

We've used an aluminum fishing boat to transport them from their locations on the lake to a flatbed trailer at the landing.....roll the lift all the way up and use rachet straps to pull it back down while you let it down from the wheel so the cross-bars are on top of the boat. Then drive it across the lake on the fishing boat.
