Humminbird transducer causes roostertail

[steelie21]

Just installed a Humminbird Helix SI transducer and at plane it creates a rooster tail that wets my outboard. I installed it as per the instructions. I have read several articles on line about this and see some homemade "guards" to prevent this. If I raise it above the bottom of the boat I'm afraid I will lose readings at speed. Anyone have any experience with this?

Same problem, and i was losing readings on plane. Raised it up, fixed all issues.

Had that on my 788 , they sent me a insert fixed the problem

I know on the other models besides the helix there's a plastic insert for the transducer. In the packaging it always looks like a cap or some extra piece that's garbage lol. I've had to order one a couple times till I learned my lesson lol.
