Freestanding hydraulic lift height adjustment

[Molarroller]

Anybody ever adjust one of these while its still in the water....and is it possible?  I have never messed with one before but have been having trouble getting someone to come out and adjust it for me.  Our lake is way down and I will most likely not be able to get my boat on it next summer.  Was wondering if it is something that I can just adjust one leg at a time and lower it down.  It sits in about 4 feet of water.

Floe lifts can be adjusted with a cordless drill.  Most others have bolts or pins for leg height and need some way to take force off to adjust.  Really depends on water depth and lift type to how you do it.

If it’s a standard lift with legs with various pin holes to adjust height. Get some floats of some sort to attach to the bunks to lift the lift off the bottom. Then pull the pins on the legs and insert where needed.

Thanks for the tips.  I have an old lily pad that would fit rolled up under the bunks.  That might lighten the load enough to take the pins out.  Otherwise maybe I will get a Farm Jack and lift one side at a time

If the water is shallow enough, a hilift Jack can be used for adjusting.  They used to use jon boats and come alongs to move lifts.  You can probably do the same to adjust it.  Make sure you lift the frame and not the bed as the bed moves freely and won’t help with adjusting.  
 

shore stations have pins for leg adjustments and unfortunately they are underwater in most applications.  Follow the frame down and you will find the pins.  The old steel ones are a pain as the legs often rust and no longer move.  Other lifts may have bolts to hold the lower legs.  Again underwater.
