I am looking to put my Searay 175 on a lift in a covered slip on Mississippi. My boat weighs approx. 2300 lbs. I know nothing about lifts. What can go wrong with them ?? What to look for when buying used ?? Price range on decent used lift for small boat ?? Any info is good since I know nothing. thanks. ken

Re: Boat Lift Questions

I bought my 5 year old 4000lb Hydro Hoist for $2500 three years ago. I had to replace the built in GFI and it was ~$40.

The older design of Hydro Hoists have metal straps under the floats. The straps rust/rot and the float will pop off sinking the hoist.

There are three common styles. Side mount for a U shaped dock, Side mount for one dock finer mounting, Front mount. attaches to the front of the dock only.

Re: Boat Lift Questions

"what can go wrong" is usually operator error if they are properly installed.

Most have a "stop" to keep you from going up too high or down too low, but they don't always work.
If you hit bottom you have a problem, so it has to be installed correctly, the stops work or you stop on time, and the bottom has to stay the same depth.
Of course, any mechanical electrical device exposed to weather can have problems.
I have seen boats pushed off the front of the lift in a storm, which is ugly.
Sometimes they raise up catawumpus (sorry to use technical terms)
Price range should be regional. Didn't know there was much market for used ones; I'd think they'd stay put once they are in.

Since you admit having little knowledge maybe you should buy new and rely on the experts on site.

don't try to work on them yourself; they are dangerous.

I guess you referring to a cable lift? A air type lift is nothing more than a shop vac and metal frame and tubes.

Re: Boat Lift Questions

Tahorover stated it correct - I am looking for the air type with floats. I have seen them with round tubes holding air and also square boxes that seem to just trap air like an upside down bucket. NOT looking at those cable type with a large wheel that raises and lowers.

Re: Boat Lift Questions

I've had an Econolift for 20 years and the only thing I've ever done to it was to grease the pivot points once. My buddy has had one for better than 30 years. He replaced the hoses once. The original hose material had some UV problems, but they changed to a different style by the time I got mine.

Econolift uses the rectangular float made out of Rotomolded Polyethylene now. When I got mine they used fiberglass. Not sure about prices.

Re: Boat Lift Questions

I've never seen these types of lifts in person.
How do they work in storms?
What keeps them from getting loose or wrecking stuff around them?

Re: Boat Lift Questions

I have seen a few ads for them ... always wondered about storms and unusualy high tides....the boat is not really off of the water.

Re: Boat Lift Questions

They float and anchor to the dock. The only high tide issue would be if your dock floated off of it's pilings. High to low tide on my body of water is 3.5', heavy storms can add 3-4'. My pilings are set up so the canal would spill over the levee before my dock would float off.

So it is not off the water when it is not touching water!?!?!?!

Re: Boat Lift Questions

The boat show season is in swing right now. Maybe you can find what you're looking for there.

If you were in the market for a candeliver style lift, I know a dealer that has a number of them at great prices--new and used.

Re: Boat Lift Questions

I've had floating lift's since my first boat developed blisters in the early 80's (fresh water lake, North Georgia). I've had a Hydrohoist, Econolift and Float Air. They were all pretty much the same. Do not buy the older hydrohoist that is not a level lift. These early lifts were held to dock with a pole and slide arrangement. When the lift comes up, the bow comes up first, then the stern. If these lifts get hung up for any reason they can dump the boat. Most lifts are "level" lift, they have a 4-bar mechanism that attaches to the dock so they come up level. The only drawback of these lifts is the amount of depth required. Usually 3' to 4'. They do make shallow lifts, that I think use as little as 30". Older lifts for a 2000 lb boat usually run around $1k to $2k in north ga. But you have to move them. Do not try and do this yourself. These lifts are very heavy and really need someone who knows what they are doing to stay out of trouble when installing. Our local companies usually charge around $500 to remove, move and install. On most lifts, the metal frame on the lift that is in the water rusts over time. Some lifts have some stainless, but most of the metal is galvanized steel. Older lifts need to be checked pretty closely. Newer lifts, like Polylift, are designed so that no metal is in the water when lifted. Most companies offer rough water versions if you get a lot of waves. If you are in an area with rough water, you'll find the lift really stabilizes the dock alot. The tanks have evolved over time. From filament wound fiberglass and some galvanized to almost exclusively thermoplastics. The newer pastic ones overcome the obvious problems with the glass and metal ones, but on occasion a muskrat or beaver can decide they are chewy and chew a hole in the tank.. This happened to me a couple of years ago. I currently have a 10,000 lb Float Air lift with 4 tanks. Replacing the tank cost $500.

Re: Boat Lift Questions

I have never seen this type of lift, but I would not trust one for my area.

East side of the Chesapeake Bay. Normal tides, and storms from the west that make it look like ocean waves breaking on the beach. There is no way the lift would survive here.

Tides can be a problem. Waves are usually not. These lifts float, with the dock (if it's a floating dock), so they don't see as severe a load from waves as you might think. Most of the people who use them around me (Lake Lanier) do so to keep their boat from being slammed repeatedly by rough waves caused by skiers, wake boarders and large cruisers plowing a few hundred feet from the dock. It's like parking your boat on a floating dock.

Re: Boat Lift Questions

Floating docks don't work around here either.

You may have to see it to believe it, during a storm with tidal surges. It's nothing like wake waves, and lasts for hours. And I'm only in the mid-part of the Chesapeake. At the mouth of the Chesapeake, big US Navy ships go out to sea to ride it out. A floating lift is just not feasible here, at all.

I wish it were not so. My pier and lifts cost way more than the boats they protect.

I understand, I actually wish we could have fixed docks on piers (Corp lake, so we can't). Newer Aluminum welded floating docks go for $40k to $50K. My friends on "open water" (not a protected cove) can not sit or walk on their docks during the summer at peak times, it really is that rough. The worse threat to us is tornados, I've seen some 32'x32' floating docks with full sundecks upside down in the trees with the boats still in the slip (that is another negative of floating lifts).

Re: Boat Lift Questions

The floating lifts are primarily used on lakes and are attached to a floating dock which is anchored to the shore by the ramp, and steel cables. Mine has 4 steel plates bolted to the dock and the arms that allow the lift to raise and lower have a single bolt attached to the plates for the lift to pivot on. I don't think a floating dock would work well in a tidal area, especially if there was storm surge.

The lake of the Ozarks level is normally kept between 659 and 660 feet above sea level, although I have seen it as low as 654 and as high as 663, so they can take a fair change in water level. Here's mine after some high water.

Re: Boat Lift Questions

update
Went to marina yesterday and picked out a 20' slip. There are two lifts for sale there by other boat owners. - 4000 lb lift and 6000 lb lift - both with fiberglass pontoon style air tanks. Have not called owners yet to see what asking price is. Also, marina has a 3000 lb lift (same style) for sale and a 4000 lb lift.
My 175 searay with the 4.3 V-6 is supposed to weigh 2300 lbs. It has 20 gallon gas tank. I am figuring the boat can't be more than 2450 at most. Would the 3000 lb lift be adequate or is it too light for my boat ??? What is a fair used price on a 4000 lb lift (as is) for mid-west mississippi river area ???

Re: Boat Lift Questions

FYI - I got a used 6000 lb lift with the fiberglass pontoon tanks- Hydro Hoist. Great Shape. I have a whole lot of boat upgrade potential now.
