Found a rooster-tail cure

[lawman]

Last fall I picked up a Hbird 958 ci Down Imaging combo unit. Had it professionally installed (that means anybody is better than me). Used it and like the unit very much. But..the ducer threw a huge rooster tail. Repositioned the ducer and made things worse. Found out after a bunch of digging there was a rooster tail plug included with the unit. Looked in the box and there it was. The installer and I both missed it. Easy to put on. Problem fixed. Have talked to other DI unit owners with similar situation. The rooster tail isn't even mentioned in the install instructions.

I have that problem, What does the piece look like? I don't recall seeing anything extra with the ducer.

I also had that with original 597 mount, supposedly they came up with an "after" market mount that fixes it within the past year. if your unit is older than that with original mount, you would have to replace mount with current "universal" mount for your locator

I have a little alumninum hood that mounts behind my ducer to knock down the rooster tail. It's not a fancy SI/DI ducer though. The rooster tail on mine would spit all over the side of the outboard.

Similar to this

Yep, i use that with my quadbeam transducer, but don't have a rooster tail problem or high speed problems with my SI transducer.

If you call or go on-line (they have a live chat feature) Hbird they will send you one for free right away. Their customer service is the best.

If your X-Ducer is the typical "skimmer" type and NOT the HDSI type (bar of soap sized) x-ducer, H-Bird DOES have a solution. For the larger, HDSI units... "No Joy" from what H-Bird tells me.

Easy fix...

The rooster tail is caused by water flowing over the top of the 'ducer. Eliminate that and you're golden. I have, I am, and will "spill the beans" as soon as my design is "protected". Works like a charm! ZERO rooster and perfect HDSI readings up to 45+ MPH! With the proper settings at the head unit that is. More to follow...

My Humminbird 798 came with a rubber plug that you put between the transducer and hull of the boat. took care of the problem.

For you guys that run a DI/SI transducer, Humminbird does have a transducer that mounts on the bottom of the boat that does not give any rooster tail. It does require a hole to be drilled in the bottom to mount to as it is not a shoot thru design. I have used these on my last two boats with no problems as all.

It is a free exchange for an unused "soap bar" transducer. This is only for the SI/DI units.

Wrap the bracket with tape?

That's what I did.
