View Full Version : 2103 X10 - Trim/Surf tab issue

05-29-2014, 12:08 PM
I have an issue with my starboard surf/trim tab. The actuator looks to be retracted or 0% deployed.

The touch screen is showing that the tab is 100% deployed. When I try and put it back to 0% deployed via the touch screen it tries for a second and then displays 100% deployed.

The manual switch is not doing anything either (it will act on the port side).

The attitude plate and the port side work fine, just starboard is not working.

I have rebooted the lcd but it still comes up showing 100% deployed.

Any ideas?

I turned off the power hoping it will drain reset the lcd to clear that.

Does anyone have a wiring diagram for the surf tabs? I could not find any of the underdash circuit breakers labeled for the surf tabs, any dies where the fuses/breakers are for these?

My boat is about 100 mile from the dealer so I'd like to troubleshoot this myself before taking it in.

Thanks, E

Wow - Future Boat - Are you a looper, lol:D

Sounds like a bad actuator to me.

My 2012 x25 just had similar issues. The dealer said it was a bad actuator and replaced it but I'm skeptical. Originally for surfing all tabs would go down. Then after cruise the center would come up and both surf tabs would stay down... Then when I deactivated cruise all tabs would eventually come up but come to find the drivers side tab actually didn't. I'm 100miles from dealer as well but there was no easy solution for this, I'm just hoping they really found the root cause

My dealer checked it out and said it was a bad actuator.

It looks like they did replace it and it all works fine now. I am like you , skeptical... I always wonder if they do what they say they did.

I was kinda of shocked that they said I was out of warranty for 3 weeks. I took possession of my boat on 5/31/2013 and reported the problem on 5/30/2014. Apparently the warranty starts the day day your build starts... ***?

But Mastercraft covered it under warranty so I guess I cannot complain, I just hope the new one (and the others) last longer than one year.

So just like last year after sitting over the winter the starboard trim tab no longer works.

This time the trim read zero % deployed but does not budge when you try and lower it.

I am very skeptical that they actually replaced the actuator last year because I got the boat back in a day or two.

Does anyone have any troubleshooting tips?

Is there a way to check or reset the control unit?

I hate to drag the boat to dealer for them to 'fix' it again, I'd much rather do this myself.

You can remove the tab, pretty simple actually, there is a set of screws on the top of the tab and an O-Ring, just remove and bench test.

I'll try that tomorrow.

So I did some research and found that Lenco does have a 3 year warranty. They have a LOT of good information on their site to help you determine what model you have and what models are used by certain manufacturers.

I contacted Lenco about a warranty claim and their reply was that Mastercraft was the holder of the warranty for my part and I would have to work through the dealer to get in replaced.

With the boat out of warranty and it being a hassle to take the boat in I decided to just order a replacement. I have figure out how this stuff works sometime and it might as well be now.

Using info on their site I ordered the proper part from West Marine and swapped it out today. It is working like it should, plus if it goes out again within 3 years I can get Lenco to actually replace it.

U should be able to find the power end of that actuator and apply 12volt to it and exercise it. I would suspect the goofy MC controls before the actuator being bad.

Before I took it off I plugged the new one it and it worked right off. The old one refused to budge.

I forgot to bring it with me when I came home but I plan to take it apart and see if I can get it working on the bench.

I have a similar problem with my X35 2012. Though the problem is intermittent for me. Some times it works some times it doesn't, and if I unplug the battery to do a complete reset and then replug it, the plate will move. Some times I just can't control the actuator and the plate stays at 100%.

Do you think it might be the same problem?
