Default Boat Lift US motors problem

I've been having problems with my boat lift electric motor. It's a Boat Lift US 4-Piling Cradle lift as described on their website http://www.boatliftus.com/cradle.php but I can't get it to work properly. The boat lift electric motors won't pick up the load. I called Boat Lift US and they told me to check my voltage and my amperage. My electrician spent almost an hour with them on the phone and he couldn't get it to work either. I purchased new motors thinking that something was wrong with them, but the new motors don't work either. These are brand new East Bay stainless steel motors and they don't work either. I live in Florida so there's a lot of salt in the air, but as I stated before, these are stainless steel boat lift motors, and they've never been used. No matter what I do or my electrician does, the motors won't pick up the boat and Boat Lift US refuses to honor their warranty. I'm paying a lot in labor for my electrician and I can't get it fixed. Is anyone else having this problem? Does anyone know how to fix it.? Is there another motor besides the East Bay motor that I could use? Has anyone else had more success getting Boat Lift US to warranty this problem?

I had a similar problem and it was a faulty plug. The plug is actually a Ground Fault Circuit Interrupter; My lift is on it's own separate breaker and I unplug it at the control when not in use so I just cut off the crappy GFCI and replaced it with a heavy duty connector. I know this seems pretty simple, but I replace the motor before I figured it out. Hey, now I have a spare motor. Good luck.

Mine is a completely new install all the way to the breaker box. Electrician has double checked everything, lift manufacturer has looked and said to go pound sand. They claim my 32 Carolina is over 27k lbs. CC says maybe 26k loaded but not over. BoatLift USA has been NO HELP. I am probably going to have a crane come and certify the weight. Then follow up for all related expenses, time, and everything else I can.

Yes. I have a Boat Lift US 15K and had a set of motors replaced. Now it works but very slowly and noisy. Kept adding grease but did not stop squealing. Electrician and Dock Installer tried to resolve problem but never could. Boat Lift US had a store in Norfolk VA but closed up shop. Another unhappy customer

Why should "I" have to do this??? Then I become the manufacturer and assume liability.........

I'm sure this isn't the issue but when I had my Hi Tide lift installed, it was wired for 115V before I had the electrician install the 230v line/breaker. It wouldn't even lift the boat half way out of the water at 115v. No problem at 230v.

Good luck.

When my Davit Master Lift was installed I had a similar issue. The carrier bearings were out of alignment and binding up when under load. Went around & around with mfg., electrician and installer until my neighbor came over and noticed the bearing issue. Works fine now.

Sorry, this may not help you, but others may find it useful. One of my lift motors took a dump on me, it would hum but not turn, or sometimes turn very slowly. Dang thing wasn't that old. Took the end cover off, (power disconnected) noticed it had a set of points inside, look like ignition points on an older car. Cleaned those, works like new again.

boatliftjack:
Is yours the 27,000 # lift? Is it wired 120 or 240 volts? Does it raise and lower with no boat on the lift?
Note Martino's post. That's the contact fpr the start winding or capacitor on the motor. If that contact is dirty, burned or corroded the motor won't develop the torque to get started.

Call Mike Konjonowski(sp?) at DECO boat lifts (800) 204-4178 and explain your problem. He may be able to help or at least steer you in the right direction. I've never seen a lift that wont lift at least what its rated for (most will probably lift a lot more). One thing you could check is to see if your lift is somehow binding. If the pilings aren't aligned well and there is tension on the beams maybe this could cause a problem.

Default Re: Boat Lift US motors problem

boatliftjack has not been back or called me on the number I gave him.....so we may never know what model he has.

On my lift, yes it works fine empty, will lift the boat from the water most of the time. The problem happens when the boat if fully out of the water and you try to get it up higher. Hitting the up switch results in the "humming" of one motor and no turning. It is wired 220. It seems like the 1.5hp dual cap East Bay crap motors do not have the balls to start up. They will just humm. They will run down every time. The motors have been changed more than once each side....once at the expense of m electrician as he thought he had done something.....worked a few times after that and then would just humm again.

Then BoatliftUS replaced them once, I had to pay labor. Same thing. NO BALLS. They checked weight distribution and it was fine and within 5%. They checked beams for deflection and had my lift installer level them. They were out 1/4" over 14' (BS) We have greased the living crap out of it and even swapped one whole motor and plate assy with the last motor. Since then Boatlift US has just said too bad go buy a bigger lift. They have not been helpfull at all. They have missed apointments to view problems and have caused me a ton of expenses. I paid thier recommended electrician to check it and he says it is fine electrically. I even have an email from them saying I am trying to lift too much beer and too many girls. Talk about crap service.

I even offered to pay to upgrade and they will not even help....they say sell my lift and buy another. Period.

My feeling is a 27k lift should lift my boat no problem, They went as far as to take Carolina Classics wet weight of 25k (includes fuel/water) then they added fuel/water/beer/girls and came up with 27005 lbs and said go away.

I had my 28 Carolina on a 16k IMM lift for 6 years with out a single problem, I wish I had used their lift again.

Seems my only recourse is to weigh the boat and sue. I have a crane company that will certify the weight. When I saw the original post from boatliftjack I was hoping to see if he was experiencing the same thing. From his post it is exactly the same thing....but no, he has not been back.

Carbo,

I don't think you need to pay a crane company to certify the weight. Once the boat is on the lift, tension can be measured at the cables and weight can be determined. That's how I knew where to center my boat on the lift to distribute the weight evenly.

They did that, that can compare cable tension front to rear for centering but not accurate enough to calculate weight. They said my centering was ok and within 5%. Attorney said get a certified weight and he will take it from there as long as it is below 27k. He said we can re-coup all costs including weighing to prove our point.

Do a voltage check at the motor with the up switch engaged. You might have 220 at the CB box but less at the motor. Less voltage means less amps and power. Less power equals less lift.

If I remember correctly the last electrician had 238 at the motors when running with the boat on it. 2 electricians have reviewed the install and they both checked that. I have felt from the beginning that these 1.5hp dual cap motors look real pretty in SST and all but are China junk underneath the skin.

If you voltage is OK--then this does not apply, but I have had the problem with moisture in the conduit and "leakage", so that there was a voltage drop. We put in new conduit (well sealed) and went to much larger copper wire from the main pannel to the lift pannel.

Measure the voltage at the motor when it fails to lift the boat--the start up load is where the problem is--not the running load.
