threw hull transducers

2 posts in this topic

two questions for the experts. Will my transducer off a lms350a work on a lcx15mt. It came with a threw hull trancducer. Never have had one. Do they read at full speed going across the lake ect. Is there any magic to mounting them. is there adjuctments as far as angle to put in boat. I have a 2090 fiberglass warrior. what if the boats bottom is angled. I'm lost amy help would be cool. thanks

I don't think the transducer for the 350a will work with the x15, although I'm not positive. Check the plugs on the back of the units to see if they're the same but I think one has gray connectors and the other has black??? If so, they're not compatable.

When you say a through hull transducer, I assume you mean a shoot-through-hull one that you mount in the bottom of the bilge? They work great, no interference or cavitation so they excel at high speed. They may lose a little sensitivity and definition by having to shoot through the hull though.

To mount them, sand down a small area in the bilge to get to the clear fiberglass, and wipe it down with acetone or something like that. Apply your epoxy to the bilge (make a big puddle) then set your transducer in - don't rock the transducer back and forth as this will cause air bubbles and give you problems - set one edge in at a slight angle then slowly press down the other side of the transducer until it's in the epoxy and level. You have to eyeball / guess at the correct angle.

The epoxy route is a permanent solution, ie. the transducer is there forever. Antoher route that I've never tried but have heard good things about is mounting the transducer in silicone. You probably won't get as good of readings in silicone, and the silicone might pop loose after a while, but the advantage is you can remove the transducer from the silicone so it's a great way to test it out and see how it works.

Hope this helps, good luck.

    • Preds make it to the finals.  I thought someone said they were the last team in and technically the 16 seed.   Who ever they face in the finals it will be a battle, hope the Sens make it.  But would be nice to see Cullen get a cup.
    • My hunt in WI this past weekend was tough as well.  I found tons of ramps, they grow everywhere in the area we hunted, but zero morels.  I saw a few pheasant backs, but did not pick them as they did not interest me.  
    • I finally just said screw it, so I picked a couple of guys that I thought would do good (Christie, and Rojas) and some over looked guys that have had a little success this year, and were from the area.  Would never had expected Alton Jones Jr, to go from 80 something place on day 1 to the top 12.  Glad he was on my team though
    • Added these for the fry pan to go with some turkey also.  
    • If you haven't planted your tomatoes yet......plant them laying down on their side. Pick off all the branches up to the top.Lay the plant in a trench and cover the stem up to the top. Put a soil pillow under the top. Just be careful not to break the stem (I have). Tomatoes are the only plant that will send out roots from the buried stem. You will wind up with a large root ball to feed the plant. This also puts the roots closer to the surface where the soil is warmer instead of deep where it is cool.
    • Another disaster. I tried making relatively safe picks, and bombed. I have gone from the top 60 after two events all the way down to just over the 90th percentile. I need to just go with my gut
    • that is what we were thinking too.

    • 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.
