jenga Posted May 11, 2011 Posted May 11, 2011 I have had a problem with my humminbird transducer ripping off when I am on plane with my boat. I had a mechanic install it. I am thinking it is in the wrong spot or to low and is catching drag from the water. I have had it rip off 3 times now. I took it to another place and they told me to put it to just to the right of my live well hole. I thought it had to be atleast 15 inches away from the prop. Here are some pictures of where it is at now and the plug hole and live well holes. Will it be okay to put it next to my live well hole. my boat is a 93 skeeter DX. Thanks, Jenga Quote
jenga Posted May 11, 2011 Author Posted May 11, 2011 I forgot to mention that I have the Humminbird 798 ci/si Thanks, Jenga Quote
Super User Fishing Rhino Posted May 11, 2011 Super User Posted May 11, 2011 Ripping off? Does it pull the screws out, or is it tripping up? The pictures are too dark to see the mounting bracket. If it's tripping up, my first guess would be that it is too low. Quote
Super User J Francho Posted May 11, 2011 Super User Posted May 11, 2011 Probably need to use a shoot thru TD. Quote
jenga Posted May 11, 2011 Author Posted May 11, 2011 If you click on the pictures you can see them better. No it is ripping off. My transducer is now at the bottom of Lake St. Clair. Thanks, Jenga Quote
jenga Posted May 11, 2011 Author Posted May 11, 2011 If I use the shoot through then will I be able to use the side imaging. thanks, Jenga Quote
Super User J Francho Posted May 11, 2011 Super User Posted May 11, 2011 Yes to down, no to side, unless you go with a TM mount. Quote
Super User Fishing Rhino Posted May 11, 2011 Super User Posted May 11, 2011 I did click on the pictures. These old eyes can make out what appears to be the base of the mount against the step, with the cable hanging down, with the transducer torn away. I have an 898. Its transducer mounted in the same place that yours was, to the right of the intakes and drains. I had mine too low at first, and all it did was to trip up, but nothing tore from the boat as yours did. What part broke? There is the steel mount, which is adjustable up and down, the plastic piece which attaches to the mount, that can trip should the transducer hit an obstruction, and the transducer, which attaches to the plastic trip piece. Only a small portion of the bottom of the transducer should be lower than the bottom of the hull. About half of mine is slightly below and about half is higher than the bottom of the boat. Set that way, it will read the depth at speeds of about forty mph. Faster than that, air gets forced under the hull, which disrupts the transmission and receiving of bottom echoes. Reading the bottom at high speeds is not important to me. Boats with jack plates often have the transducers mounted on the transom. As soon as a boat with a stepped hull gets on plane, the transducer is out of the water, rendering it useless. Quote
Super User Wayne P. Posted May 11, 2011 Super User Posted May 11, 2011 Rhino, the transom mount Compact SI transducer for the 798 is all plastic. Yes it is fragile as compared to the HDSI transducer mount. Jenga, the best application for that mount and any other SI tranducer for console use on thin hull fiberglass bass boats capable of 40 mph+ is to mount the SI transducer above the hull bottom for off-plane use and add a shoot-thru 83/200 kHz transducer (XP 9 20) inside the hull for on-plane depth reading. Connect the two transducers to the display with a AS SIDB Y cable. What that does is disconnect the 82/200 kHz from the SI tranducer and connect the shoot-thru in its place. Many bass boat owners that have jackplates mount the SI transducer to the jackplate. For slower craft, a transom mount setup works fine for SI/DI/2D. I'm not familiar with your particular hull design, but if it has sponsons like the newer ones, you have to mount it lower than just the standard mount allows. Quote
jenga Posted May 11, 2011 Author Posted May 11, 2011 Thanks for all the info guys. I don't think I should have to pay more money for a thru hull transducer after I just spent 1k for it. But if I have to I guess I will. I was wondering though if I put it right next to those live well holes and make sure that the transducer is above the bottom of the boat will it be okay. Or do you think that the prop will cause to much turbulence for it to work properly. Thanks, Jenga Quote

Thanks, Jenga If the transducer is not below the hull bottom, then it won't interfere with the water flow off the hull to the prop and water intake for the motor. The outboard prop won't affect the transducer at all unless you have the engine in reverse--water has already passed over it before it gets to the prop when going forward. The best location is a little higher (at the step if your hull has that type is transom). A reminder: there is no one-size-fits-all for any brand of sonar transducer. The one that comes standard with all units is the one that fits the most applications world wide (that is why it is the standard). Don't get the thru-hull transducer, get the shoot-thru hull transducer. There is a difference. If you send me a picture of your transom at the hull bottom level and on the starboard side of the motor, I will mark the best location for the SI transducer and return it to you along with mounting suggestions. purdum43@aol.com Quote
humminproblem Posted July 10, 2011 Posted July 10, 2011 i have had the same issue and have lost 4 transducers, 2 installed by me and 2 by 2 separate boat dealers on 2 diiferent boats. there has to be an issue with the bracket on the 797 and 798, have these interlinked. I have contacted humminbird and I have never been more dissatisfied with a company. Cannot even get a recomendation or suggestion on how to fix this issue. anyone?? ponsnwm Quote

As I mentioned before there is no one-size-fits-all for transducers and mounting. The standared transducer is just that "standard". Some applications take different solutions. A mis-applied transducer is just as likely to fail no matter who installs it or how many times it is mis-applied. Quote
