Lowrance LCX-27c

26 posts in this topic

Do anyone of you have this unit? I just bought mine today at the bargin cave at Cabela's. I havn't even had it in the water yet. I noticed it has a radar page but I couldn't make it work. You guys know anything about it. I-[PoorWordUsage]-u-me the map page is just like my h20? and the sonar is just like my old one (it better be better though). The 220 page manual doesn't say much about radar though. So please fill me in if you have any knowledge.

Thanks again guys I'd be lost without this forum!!!!

That is a additional electronic to add on to the network if you would like it to work. I looked at the cost and it is pretty expensive but it sure would be nice to have. If you go to there HSOforum you can see all models that are compatible with your unit.

You cannot have radar reception unless you have a radar dome/antenna. The are between $ 1500 and $ 2500.

Unit works pretty good except in shallow waters.

Valv do these units use the water for some type of reflection of the signal or just reception of it ? The only reason I ask is because of them not working properly in shallow water.

I have the 28cHD which is essentially the same as the 27 except it has a hard drive and it works fine in shallow water. All you should have to do is turn the sensitivity down to help with the shallow water issues some have, but I run mine in manual mode all the time so it's no big deal to me. I like to tweak and adjust the gain up and down depending on where I'm at.

Probably wouldn't hurt to check to see if it has the most recent updates from Lowrance, although I know I'm running firmware that is a few revisions behind what is currently available and it works so why change it.

Enjoy your new graph!

I'm also wondering how much you got it for? Just curious because I picked up the same unit at the same Cabelas (Rogers I'm assuming) in the bargin cave. I got mine for $450 and the unit was brand spanking new, never out the box.

Hope you got just as good a deal and you'll love the unit.

Let me clarify I bought my LCX-27 in February when most people were still thinking about ice fishing. I actually was looking at a 522C unit for $450 that was right next to the LCX-27 that was $470. I had to do a double take thinking I misread the price on the LCX, but it was correct. And if the $470 wasn't low enough I bargained an extra $20 off of the price.

I've never seen the LCX-27 that low since, but I guess sometimes it pays to be in the right spot at the right time. Anyways I hope you are enjoying your unit.

Did that also include transducer and external GPS puck?

If so, good thing you didnt buy it last summer like I did...paid over twice as much. This was right before they came out with the HDS units.

I had to work some bugs out of my 27 but it is now working great and I like it.

yes it came with a trancducer and the gps "puck". So far I love it. It marks fish really well and the gps finds satelites almost instantly when I turn it on.

Just wondering some of the "bugs" you had to work out and how you went about it. The only real problem I am having with the unit is doesn't get a great bottom reading at high speeds, but that is not much a problem and most likely that is a motor/prop and transducer placement problem.

when I hooked mine up I found an empty spot on the fuse block and powered it right there. when I start the boat sometimes the unit will turn off other times it wont. any ideas what is going on?

Tuds75,

What is your ping speed set at. If it's not set high enough you will lose readings at high speed.

Tuds75,

What is your ping speed set at. If it's not set high enough you will lose readings at high speed.

I'm pretty sure my ping speed is set at 90-100, but I can't be sure since I am not near my boat. But I'll make sure to double check the ping when I'm on my boat next. Should it be maxed out at 100 or is there a better setting for the reading at high speeds.

Badfish, I noticed that problem with my LCX-27. Just the last few times on the water, the unit has turned off when I start up the boat. I am able to turn it back on right away, I just associated that problem with my battery running low, but since you are having a similar problem, maybe there is something to it. I am curious to see what other know about this problem.

Tuds75,

I checked with a friend of mine that is a marine mechanic and you are probably right. He said if you are losing bottom contact at high speeds its usually cavitation or air bubble interference with the transducer. It could also be main motor interference. I have a through the hull transducer on my Triton and I seem to lose bottom sometimes at high speed on my HDS5 as well. Could be an upgrade problem but I think I'm having the same problem with the transducer as you might be having.

I installed my 27 this spring and had problems right off the bat that I've been able to correct.

I had issues with finding bottom at high speed. I moved the transducer a little further from the outboard and it solved the problem. I have my ping speed set at 75% most of the time.

The unit would also turn off when I turned the key for the outboard. I started simple and cleaned the terminals on my battery and applied a heavy dose of dielectric grease. This has not been an issue since I cleaned the terminals in April.

One other thing to note for 27 users is that Lowrance posted a new software update for the 27 on July 29. It is version 2.5.0.

Just wondering some of the "bugs" you had to work out and how you went about it. The only real problem I am having with the unit is doesn't get a great bottom reading at high speeds, but that is not much a problem and most likely that is a motor/prop and transducer placement problem.

Here is what I had to work through with my LCX-27c since buying it last summer.

PROBLEMS:

1. Graph shuts off when I start the main motor.

2. GPS module not responding..intermittent problem.

3. Loose bottom signal at high speed/planed out. Anything over 20+MPH.

4. Loose bottom in shallow weedy water.

5. No bottom resolution in 35'+ with soft bottom.

I think that's all the main ones..

Solutions:

1. At first I thought it was a bad starting battery, or should I say too low MCA's (marine cranking amps), CCA (Cold cranking amps)and other battery capacity (because the batt was new). The battery that was in the boat when I bought it was a 600 mca. So I spent the $$ and got a new 1000 mca-didnt fix the problem. I have a 115hp 2-stoke on a lund fisherman where I had the graph power hooked into one of the dash accessory switches. Apparently there was enough of a voltage drop to kill the graph when I would turn over the big motor. I also wanted to put some interior lights and other new stuff in the boat..and had no more acc switches to use because others were being used for radio's and such. I then got a separate 4-switch block from the big-C and installed it and hooked the graph power to that. By doing this I essentially hooked the power directly to the battery and got it on a separate power source as the ignition. Since then my graph has not shut off when I start my big motor.

2. Went to a heavier gage wire to power the graph and antenna and re-did the connection. I originally had 16 ga and bumped it up to 14 ga. I may not have had a great connection to begin with but I have had no problems since the fix.

3. First off make sure its not directly behind a row of rivets as this will cause air bubbles and a little cavitations. I think I have mine in the center between two rows and I have a good stream of water while on plane. Since I was ok there, I Lowered the transducer straight down. Start with lowering it about 1/8" and test it to see what the graph shows. Lower again if the first adjustment didnt work. I almost always run my ping speed at 100 also. Now I have a great signal at 30-40mph where before I had almost nothing.

4. Updated the software from version 1.8.0 to version 2.4.0. Lowrance added a shallow water mode that helped take care of this problem. I think there is a 2.5.0 version out here as of recently. Playing with sensitivity can help with this also.

5. After storing the boat in cold storage(head unit stayed inside and out of the cold) my unit lost overall resolution this spring. I would have the sensitivity @100 and have a hard time seeing bottom in 35'+ and would never see fish arches. At first I thought it could be a software thing with shallow water mode or another graph setting, but lowrance sent me a replacement and it ended up being a bad transducer. I now rarely have the sens over 65, and thats in 50-60'. From now on when I store my boat, I am going to take off the transducer and GPS antenna just to be safe.

Sorry for the lengthy post but hopefully some can find it helpful. Im no mechanic, and my solutions may not work for all, but now my 27 just sings! Its nice to finally have everything working on it like it should..because they can work great!

Amazing how spending a couple hundred dollars to get a good unit requires so much more time compared to the ol fashioned flasher.

One other thing to note for 27 users is that Lowrance posted a new software update for the 27 on July 29. It is version 2.5.0.

Is the best way to get this update on my LCX-27, is the download it from Lowrance.com to my computer and then put it from my computer to a memory card and then install it from the memory card to the LCX?

Or is there another/simpler way to get the software update?

Thanks in Advance.

    • BEFORE BEGINNING

      Before you begin, make sure you have a good strong battery and make sure it's charged up. If you have a bad or weak battery, you may want to replace it because if it doesn't crank good and strong, you are likely to get a low, inaccurate reading. Make sure your engine is warmed up to operating temperature(if possible). About 10 minutes of riding should do.

      First, take out the spark plug and thread in the adapter for the compression tester. Make sure you have the correct size adapter for your particular ATV. Slide your kill switch to the "off" position. Some ATVs won't crank over with the kill switch in the "off" position, so if yours is like this, then you will need to either unhook your ignition coil or ground the end of the spark plug wire to a good ground. You can use a jumper wire with alligator clips on each end to ground it. Next, make sure the throttle is in the wide open position. You can either hold the throttle lever with your thumb or you may be able to tape it or use a zip tie to fasten it to your handlebars to hold it in the wide open position. If you don't have the throttle in the wide open position, you will probably get too low of a reading. Also, if you are testing a newly rebuilt engine, the engine needs to have been run for, at least, 30 or 40 minutes or you will probably get too low of a reading.

      NOTE: Before you begin with the actual test, make sure the threaded adapter is screwed in good and isn't leaking any air out around it.

      ACTUAL TESTING

      With the throttle in the wide open position, push the start button and crank the engine over until the hand on the gauge stops moving. Each time the engine turns over the hand should raise a little more until it reaches the maximum compression of the engine. When it stops, that is your compression reading. This usually takes no more than 10 seconds. Try to avoid cranking an engine for more than 10 seconds at a time as this is hard on the starter and the battery. Now, push the relief valve on your compression gauge and that will reset the hand back to zero. It's a good ideal to repeat the test a couple or three times to make sure you get an accurate reading. On kick start models, it will be the same procedure, but obviously you will be kicking it over instead of using a start button. Worn piston rings and cylinder walls will increase the number of strokes it takes to reach the maximum reading. If you're kicking, it could possibly take as many as 10-20 kicks to get the highest reading.

      THE READING

      You will need to check your repair manual for your particular model for the correct compression specifications. See note below. Usually, an engine will run OK if it has at least 100 PSI of compression. Most engines will have somewhere between 100-250 and some as high as 300 PSI, depending on the engine. Sometimes they will run with under 100 PSI, but usually not very well. If you get a low reading, you can do a "wet test" to try to help determine the problem.

      If your reading is too high, then you probably have carbon built up on your piston and combustion chamber.

      NOTE: You may get a low reading on some engines because some engines have a decompressor assembly built into the camshaft. Check the service manual for your quad to see whether or not your quad has a decompressor assembly built into the cam.

      WET TEST

      If you got a low reading, pour about 1-2 teaspoons of clean motor oil down into the cylinder through the spark plug hole and do the compression test again. If your reading increases, then your rings or cylinder walls are probably worn. If your reading doesn't increase, then it's probably your valves. You could have a bent valve, you may have leaky valve seats, or your valve clearance may not be adjusted properly. Also, low compression can be caused by a blown head gasket.

      CAUSES OF LOW COMPRESSION

      *Worn piston rings or worn or damaged cylinder walls
      *Leaking valves
      *Valve clearance not properly set
      *Blown head gasket

      CAUSE OF HIGH COMPRESSION (stock engines)

      *Carbon buildup in combustion chamber and on piston

      NOTE: Compression testing is a good way to keep track or "gauge" the wear in your engine. When you first get your ATV or when you rebuild the engine in your ATV, you can do a compression test and then later on, you can do them periodically. This will help you determine the wear in your engine each time you do a compression test and will guide you in knowing when your engine needs rebuilding.

      This is about all I can think of. I hope I didn't leave anything out and I hope this helps everyone with their compression tests.
    • As dumb as this sounds how is this done?
    • Try a compression check. And make sure the choke is opening all the way.
    • They are not the best out their but for the price and your average person not too bad I guess, Its going to send lead to where its pointed. This is probably what is going to happen he is going to buy a package shoot it for awhile then start upgrading everything to how he wants it and it is going to end up costing way more than if he just built one himself how he wants it.  
    • Hello, well I convinced my brother in-law to pick up my buddies old 1980 185 although pretty sure he said it was bored out to a 200? Here is the deal it's been sitting for a solid 8 years. I know it ran fine before. Not the delema-----   It starts right up (he bought a new carb odd amazon) although it sounds like a jet with high rpms. Looked at the throttle cable that's fine. Floats are fine. So he plugged this hole in the air filter and got it to idle down although when he hit the gas wouldn't get any power. Read a few things online and they tell you to just bypass the filter box and all that so back to amazon we went to get one of those filters that mount right up to the carb and it's still the same issue..   I just haven't seen anything like this? Do you guys have any thoughts or tricks that we/he could try?! Thanks in advance
    • Hi Everyone,  I'm looking into buying my first true fish finder and I'm a little perplex with the mapping card situation.  I'm looking at Humminbird Helix 5's and 7's.  I'm drawn to the autochart feature.  From my understanding, you can record 8 hours of charting onto the internal storage, but, is there any native mapping included on the unit or do I absolutely have to get some sort of mapping chip, zerolines or lake master, or navionics?  Can I store data on a blank SD card?  I've been researching this a lot and haven't found any conclusive answers. Thanks everyone!
