Thread: first trip with 797si pics

Crip47,
Nice bracket - though I would be worried about causing a cavitation bubble in front of the propeller with the transducer mounted there which could cause the propeller to blowout. Hey if it works for you than that’s great. I assume you do get high-speed readings than and if so at what speed is "high-speed"? Most fishermen don’t ever say anything when something works (transducer mounting or other) but they sure do when something doesn’t work! It would help if the Yahoo Si Group folks, or anyone else for that matter, would also post how there Si units worked after they have mounted the transducers. This could than be used by anyone else who may have the same or similar boat and would let tham know that the transducer was mounted for low speed operation only.

Since that Si transducer costs about $200 to replace it, many mount it up higher on the transom so that it will be more protected and also install one of the High-Speed Side Imaging Kits (Si-HSK). This consists of an inside-the-hull DualBeam Plus transducer and a transducer switch. They switch to the inside-the-hull transducer for sonar readings at high-speeds since the Si cannot update fast enough to show good detail at high speeds and than flip the switch back when they want to chart an area.

Welcome to the site Greg. We appreciate anything you can bring to the table. This is the best unit I’ve seen and I’m around this stuff every day. And yes, there is still room for improvement. You’ll hear the good the bad and the ugly. Hopefully you’ll take our thoughts back to HB. The unit works good up to 44mph. that as fast as I can go. I looked into the second transducer and switch but didn’t you say in one post that you need to go into the units setting and change it when you switch? If not I’ll give that a try. I’m also working on building a shim for the transom so it can set square. I don’t think it would take an engineer long to design an adjustable transducer bracket for the transom. That would be one nice feature. Once again welcome

Crip47, welcome back is more like it. Work at the job and home has kept me from helping out here and other places. I should always be available by e-mail though.

Here’s the deal with the additional transducer, switch and menu: you can leave the unit in the Side Imaging transducer selection setting (“Hi-Def Sidescan”) and simply flip the switch for high-speed readings but you must be aware that anything you see on the Si sonar will be junk. If you don’t want to see this than change the Transducer select menu setting to “Dual Beam” menu setting and you will not have any of the Si sonar Views available, so you won’t see the junk Si readings.

There is always room for improvement and I take all suggestions as such. The design folks, Engineering and Marketing all get e-mail messages from me with suggestions for new features, functions and even accessories. The problem with accessory suggestions is that if the powers-that-be don’t see a return on investment – they won’t happen. One day I will retire and start producing a line of aftermarket sonar accessories!

Humm. Greg, i would say it would be wise to have a rep. at Reelfoot @ classic and have them bring at least 20, 997 si transducers because they gonna need em.
