I own a 96 253 convincer. I am having trouble with my engine hatch lift, I am getting 12 volts to the unit, but it still won't open and close reliably, can this be rebuilt or do I have to get a new one? It is a acculift MQ347. I can't seem to find the co. on the net. I hope Kip or Mike can help me out.

Try C P Performance online.I think IMCO makes a nice one.Mine is going too.
I have figured a way to open the hatch if it won't open. Take out the vent on the outside of the hull, stick a broom handle or something strong in the hole and knock the clip off and then push the pin out of the ram at the hatch. I HAVEN'T HAD TO DO THIS YET! I hope I can fix it before it comes to that.
Up date on hatch trouble.
I have discovered that the ram is o.k. I had my son operate it, and I used a volt meter at the motor, when it stopped working I had no voltage, when it started working again I showed voltage. Sometimes it would work real slow, when this happens I was only showing 7 or 8 volts, what does everyone think?
I pulled the switch and breaker to look at it, but wow! it must have 10 wires hooked to it, so I think I will try to get a new switch and breaker before I pull all the wires off this one.
The switch is a toggle type, it has the number of 9448 on it, Hope Kip or Mike can help.

I can vouch for this, I had to do it on my old persuader. Works like a charm, just hope you don't have to do it on the water.

The ground wire on my hatch motor broke off once. I had a hell of time getting it opened without destroying anything. Now I took an old Morse cable and attached it to the pin on the hatch. I hung on the cable on the underside of the hatch running to the edge. All I have to do is lift the hatch enough by hand to get a finger or 2 on the cable and give it a yank. The pin comes right out real easy.
up date on my last post.
problem not solved. I was winterizing the boat yesterday, and when I went to close the hatch It wouldn't close. I had the wife operate the switch and I was only getting 5.5 volts, I dont know whats going on. I took the old switch to the electricion at work, he took the old switch apart and all the contacts were (carbond up.) You could scrape it off with your finger. He also took the motor apart and said all the brushes looked great. He tested the motor and said it worked fine, so I am at a lose.
Now this morning I tried it and it is working fine. I need help, if I can't get this fixed this fall it will drive me nutts by next spring!

How about a pic of your pin removel set up?

My Velocity has (2) relays located on the engine bulkhead. Possible that you Checkmate owners are suffering from weak relays? Changed mine after I pulled the ram apart, inspected, cleaned and lubed it and haven't had a problem for more than a year now. Would explain the voltage drop you guys describe. Hope this helps.

I recently bypassed all of the inline fuses near the battery box. (I ran new wires rather than try to seal the original ones up) They were always causing problems, (blown fuses or corrosion) and were located in a bad spot for water to get at them. I installed inline fuses at the devices that needed them in better locations and it worked out great.
After this year, I don't give anyone a hard time over a boat that runs, I've been towed back twice aready. (2 blown outdrives)

First of all all electro hydraulic hatch lifts are made by after market companies. and all can fail sooner or later, wiring that is exposed to elements can corrode. just because a few guys are having some problems with thier lifts any boat made can experiance this problem. So far I havn't had a problem with mine yet. So I wouldn't say us checkmate owner are suffering from anything. I could have bought any boat I wanted I bought a checkmate and I proud to own it.
