View Full Version : Side Image Transducer Rooster Tail
Need a little help here...I bought a new 997 humminbird and the transducer sprays water all over the engine and throws a rooster tail. Not really a problem now but this winter I am worried about the water freezing stuff up. How can I fix this??

A few guys have came up with a sectioned PVC pipe fix that directs the spray downwards. Maybe one of them has a picture they can post of it.
I believe Hummingbird has also mocked up a prototype of a deal designed to solve this ducer spray issue?
Not sure if it is available yet?

Have you tried adjusting it so it doesnt throw a rooster tail? Mine spits some water on the engine cowling, but no rooster tail so speak of, but it did with my initial installation.

Which way did you adjust it?? I have not moved mine as it reads and works awesome....Just spraying the crap out of my motor!

Call HB tech support - they will send you a fix for free. It consists of a rubber piece that fills the gap between the transducer and bracket.
It's included in the new mounting kits - they will send you the entire kit.

Not sure HB is sending the plug for free anymore. Or so I heard. I wrapped the slot with 5-6 rounds of electrical tape. Problem solved and has not come off yet .

That's by far the easiest and cheapest way to address the problem. Watch out in the winter if you run in an area with ice chunks (like the open waters of the Mississippi where I fish). A transducer mounted so low that it throws a big rooster tail is begging to get knocked off by a chunk of ice.

Set it up so its flush with the bottom of the boat and not tipped down at the rear so the water washes across it. They are not supposed to be installed like the high speed skimmer transducers in the past. Too much surface area. It shouldnt affect the readings if its installed like this.

I mounted a shield to redirect the spray back down as I had the same concerns about late fall freeze up. I would have perfered not to drill into the boat again but had to do it on the fly during a trip.

If it is an aluminum boat I would first install a transom saver. This will keep you from drill holes in your boat due to adjustment of the transducer. The transducer needs to be mounted 1/8 to 1/4 of an inch below the hull of the boat and the transducer needs to be very straight. It does not need to be tilted down.

I filled in my hole (where the plug goes) and taped over. Little effect. Moving up I could reduce the spray, but did not want to mess with the great returns I get at all speeds. So I made a spray shield. problem solved. Pics from my gallery:

The boat already has one on it from the factory and its very strait. Thanks for the help though and I am going to try to get it worked out this weekend. Prolly try to fab a shield.
