Location: Duluth, MN | Hey guys,
I just picked up a side imaging humminbird. I need to mount the transducer on the boat and was wondering if anybody had any input as to the best location to get the best performance?
Also i have heard of guys running a seperate ducer for high speed readings. Is it really necessary ffor me to purchase another one or.can i properly place mine to perform at high and low speeds?
Any info much appreciated. Pics would be awesome. Feel free to email me. Bowtech162@yahoo. Com.
Headed to vermilion for a week on Friday and would love to have this unit up and running.
Thanks,
Bob |

| Hi Bob,
Were a V now and the weather is beautiful. Going out tonight for the big ones????????
Anyways check this website out that I found before I mad my HB purchase. It is loaded with information and just ask Doug or Wayne questions regarding your HB.
http://www.bbcboards.net/humminbird-sonar-gps/
My HB is installed at the transom and works great. You will probably need the thru hull if you want it for speed though. I believe the side imaging and down imaging only works at low speeds but I could be wrong.
Good luck next week.
Dan

Location: Duluth, MN | Thanks dan Good luck, stick a pig!
I only need side imaging at low speed. Im just hoping I can get by with one ducer and have normal 2dbabe readings at high speed. |

Location: Duluth, MN | Ok, new question. How tough is it to bobd in the thru hull ducer? |

| You will need 2 transducers to get the most out of your unit. The big transducer (for yhe side finder) needs to be somewhat centrally mounted to get the best readings on both sides, it is recommended that you stay at least 15" away from the prop. I'm mounted about 12" away and would loose readings above about 25mph. So I mounted a second transducer outgoard on the hull ( about 24") away from the prop and have no high speed issues.baptismrneopi |

| You might do a search on here to see how Lambeau did his on a tuffy x-190 a few years ago. I have posted the pictures here. As said elsewhere, as far as I know, (I have been wrong before.) you can only use the side-imaging and down-imaging at low speed, so there isn't any need to subject that transducer to the dangers of being mounted below the transom. The conventional high speed transducer was mounted inside the boat, glued down.

Location: Mauston, Wisconsin | On my Skeeter w/stepped transom, I mounted the SI transducer on the lower center of the transom above the keel exactly as shown in Dave F' s photo's, but centered on the main motor (I have a jack-plate) so there's enough clearance, the motor & jack-plate actually protects the SI transducer if you back into an object or the wind pushes you into a dead fall, rocks, etc (its not a cheap part). If you don't have that much clearance between the motor & transom, you need to make sure that the motor doesn't obstruct it when trimmed all the way down. If the motor obstructs the transducer, you need to mount it far enough down to have 180 degree unobstructed horizontal view of each side of the boat. The motor, trolling motor, kicker, other transducer's, etc cannot obstruct the SI, if so, you will have poor performance in SI mode.
Its easy just imagine you have a very large upside down protractor large enough to stretch across the transom w/ the transducer installed at the top of the protractor center - nothing in the area of the imaginary upside down protractor should protrude more than ~ 1 1/2 inch.
I also installed a thru-hull transducer & transducer switch, easy to follow instructions from HB w/ the switch & thru-hull transducer.
Have fun!

Location: Duluth, MN | Thanks for all the info guys. Im gonna go with the 2 ducer option. A high speed thru hull and y cable are under a $100. Anyone see any reason not to mount the si ducer on the lower step next to the livewell/baitwell intake? Anyone have theres nounted there on a 620? I saw some guys pics on the net mounted this way.
Al you mentioned a switch?? I was told by the dealeras well as other guys that the unit will automatically switch after it starts losing signal with the si ducer.
Thanks again,
Bob |

Location: Mauston, Wisconsin | Mine is a older HB 997SI only has one transducer input. I would avoid the lower step- to easy to damage the SI transducer via rocks or submerged timber etc. If the wind or current drifts you into rocks or submerged timber, do you think the transducer can take the weight of the boat?
Have fun!

Location: Duluth, MN | Mine is also a 997. Dang now i have to determine whether or not i need this switch... |

Location: Mauston, Wisconsin | If you have a 997SI - Look at page 11 of the manual. I think you need the switch, my manual shows a single 7 pin transducer input.
Call HB & register your unit, then ask for tech support, they can set you up with right stuff -They have outstanding tech support.
Good luck!

Location: Mauston, Wisconsin | bdog- This might help. I don't see how Y-cable would work maybe I'm wrong, let me know what you find out. I'm just curious, and don't want to waste their time w/a phone call from someone who already has it installed & working with the transducer switch.
Good luck!

Location: Duluth, MN | I was looking at the stuff last night, and it will hook up. Whether the unit switches automatically remains to be seen.
How it works is the single end of the y cable plugs into the head unit and on the y end there is a plug for the si ducer and the high speed ducer. So neither of the ducers plug directly into the back of the unit, just the y cable single end does.
Confused yet? I am lol!
Im rigging it up tomorrow and will let ya know what i come up with. Looks like running all these cables and wires is gonna be a huge pain in the nice try on a ranger boat.

| Good luck getting this to work. I have a thru hull in the sump area as well as the SI transducer on the back of my 620 connected with the Y cable to my 1197 and I lose my depth reading at speed. I have been on the phone with HB who claims this should work but...no luck so far.
Please be sure to post how it goes for you.
Thanks! |

Location: Duluth, MN | Guest,
Is your si ducer mounted so that its out of the water when yoyr up on plane? I was told this makes a difference. |

Location: Mauston, Wisconsin | bdog - I checked all the wye cable options/accessories on the HB website for an HB 997SI. There is no way a single wye cable can combine two different transducers, i.e., other than two SI transducers- the SI wye cable is for if you have interference from your motor or something else - then you need two SI transducers, one SI transducer is mounted to the right and the other is to the left. The wye cable feeds each left & right transducer signal to the 997SI -> left+right= complete picture.
A SI transducer and thru-hull transducer requires a switch. I'm outa here!
I think the problem is how the question is posed. I thought of Shep & JLong when I saw this!
"Two engineering students were walking across campus when one said, "Where did you get such a great bike?"
The second engineer replied, "Well, I was walking along yesterday minding my own business when a beautiful woman rode up on this bike. She threw the bike to the ground, took off all her clothes and said, "Take what you want."
The second engineer nodded approvingly, "Good choice. The clothes probably wouldn't have fit."
Have fun!

Location: davis,IL | Mine required no switch, just contact Humminbird. They told me which "y" cable and which transducer for my unit (981 csi updated with 2010 software). I assume the new transducer ( a 200 hz unit) runs the basic depthfinder, while the sidefinder transducer runs all of the higher frequencies. I now have good high speed readings (40+ mph) as well as my low speed down imaging and sideviews. |

Location: Duluth, MN | Took it out last night and everything worked great! Even put a 41 and a 42 in the boat. Thanks for all the advice. |

Location: Mauston, Wisconsin | Well, I guess I learned the HB website is little incomplete on this topic and that I as given bad advice in 2009. Glad it all worked out for you. Did the Bird help you put them in the boat?
Have fun!

Location: Duluth, MN | As a matter of fact the lakemaster chip/mapping capabilities did help me find a weedy hump i never knew existed. Moved 2 off the spot and bagged one.
