Operating Your Boat Lift
What size boat lift do I have? How can I tell what size the boat lift is?
We can help you determine what size of lift you have, but we will need to know the diameter or width/height and length of your tanks and how many tanks you have (you can also email us a photo).
My boat lift will not go down. How do I get my boat lift to lower?
Verify that there are no obstructions keeping the boat lift from submerging. Also, check to make sure the hose is not kinked and trapping the air in the hose. Lastly, if this is the first time you are using it after a long period of time, the unit may be air-locked. For manual controls, place your valve handle(s) in the lift/launch position and turn on your blower to purge the hose and tanks. For push-button controls, press the raise button. You may also need to raise the hose up out of the water to get any water that may be trapped not allowing the air to release (it’s good to cycle the lift a couple of times if this is the case to get the hose cleared).
I have a wide boat slip, is there any way for the boat to be lifted to one side?
Yes, we can customize the installation to offset the boat to one side of the boat slip.
Can my boat lift sit on the ground with the boat on it?
In most cases, if the lift has to sit on the ground because of lack of water, your boat will be fine for the short term. If the bottom is extremely unlevel or rocky you should remove the boat before this condition occurs.
How much air pressure is in the boat lift tanks when the lift is fully raised?
1-3 psi is in each tank when full of air.
Is there an assembly manual for my lift?
Under the “Resources” tab for this website click on “Installation Manuals” in the Resource Info column to locate your particular lift.
What is the average time for my boat lift to raise/lower?
Our exclusive 1 ¼” hose allows for HydroHoist Boat Lifts to raise and lower faster than any other hydro-pneumatic boat lift on the market. For lifts 8800# and under, generally, this is less than 4 minutes. If your lift is fully raised without the boat on it, the lowering time will be substantially increased.
What size of generator is required to power the lift?
Lifts 9000 lb. capacity or less have a single blower control and are operated with a 2000-watt generator. Boat lifts with greater capacity have two blowers and will require a minimum of a 3000-watt generator.
An 1800-watt generator is recommended for elevations below 1000 ft. relative to sea level for a standard one motor control. The motor requires 1427 Watts @ 12.5 amps for standard controls with a max open wattage of 1659 watts. For high-performance controls, the values are 1555 Watts @ 13.9 Amps with a max open wattage of 1795. Contact your generator supplier for information concerning rating specifications for environmental considerations such as high elevation, temperature considerations, etc. The controls are designed for 110 A/C residential circuits. Alternative power sources are possible, however, the owner assumes all responsibility for the additional cost of equipment and ensuring that the alternative power source is sufficient to power the unit.
My lift is leaking down a few inches over a span of a couple of weeks. Is there anything I can do?
Yes, check your hose connections and tighten if needed. We recommend checking your hose connections twice a year. Test the valve to make sure you are still getting an airtight seal (use soap and water on any connections or even the tank if needed to look for possible leaks).
After I lower my boat lift, it pops up as I remove the boat. What is wrong?
Your lift is most likely air-locking due to a “stern-up” condition. Contact your nearest HydroHoist dealer for assistance.
Do you have a retrofit kit to make my control a remote?
No; however, we can recommend after-market remote control manufacturers. Please contact HydroHoist Customer Service.
My control box is tripping the power when in use. What is wrong?
Your control box motor(s) may need to be replaced. This problem could also be related to the GFCI’s on the box and/or outlet. Contact an authorized HydroHoist dealer for more information.
Do I need to unplug my control box when the lift is not being used?
While it is not necessary to do so, unplugging your lift when not being used for extended periods of time, could prevent a “lightening-strike” power surge that could damage the control box GFCI or Control Board.
Do the control box valves need to be closed when the lift is down?
Yes, this will keep water from backing up into the manifold and eliminate water from getting to the motor or spilling onto the dock. To close your valves on manual controls turn the valve handle to the dry dock position. On push-button controls, press stop.
My control box has a “Rapid Launch” feature; what is that? (Controls made before 2006)
This feature was available on most multi-valve HydroHoist lifts (Before 2006). It allows for a larger volume of air to be displaced from the tanks at a higher rate of speed. Periodically, with the lift in the “up” position, pull up on the “Rapid Launch” handle and turn the motor(s) on for 5-10 seconds with the valves closed. This will remove any moisture trapped in the manifold that could shorten the life of the motor(s). If your control unit is equipped with a “Rapid Launch” you should use this feature each time that the lift is lowered. Note: The Rapid Launch Handle must be down when raising the boat lift.
The motor(s) in my control box are louder than normal; do they need to be replaced?
If the motor(s) make a metallic sound while in operation, it more than likely needs to be replaced. Contact an authorized HydroHoist Dealer for more information and to schedule a service call.
Is there a proper sequence to operate the valves on a three-valve control box?
When operating a three-valve control, the left valve handle and the right valve handle should always be turned simultaneously. The center valve handle is then opened/closed. This should be done when both raising and lowering. Doing so should help reduce the need to “feather” the outside valves to overcome an un-level condition.

How can I tell what replacement motor I need?

How can I tell what tank band I need on any lift?
The standard tank bands for the older style lifts with fiberglass tanks were either 24″, 30″ or 32″ in diameter. You should be able to measure your tank diameter and confirm what size tank bands you need. If you have a side-tie/B-Model Lift, we advise sending photos to HydroHoist Customer Service to determine your needs. Most tank bands can be purchased on TotalMarina.com!
Used Boat Lifts / Rental Boat Lifts / Trade-In Boat Lifts
Is there anything I need to know before buying a used HydroHoist?
You will need to verify that the lift model will work for your dock application. Also, verify that the capacity of the lift is adequate for your boat.
Does HydroHoist rent boat lifts?
No, however some of our Dealers offer financing options (please contact your dealer for more information). Some Marinas have leasing opportunities as well.
What is my boat lift worth? How much is a lift worth I found on Facebook/Craigslist?
Pricing will vary depending on the age and overall condition of the lift; however, typically a used HydroHoist lift will be about 75% of the cost of a new lift on a comparable model and capacity. Pricing will vary depending on the age, condition, market, and season.
I need a bigger lift, do you take trade-ins?
Yes, many of our HydroHoist dealers take trade-ins. Call your local HydroHoist dealer to inspect your lift and discuss trade-in options.
