Two problems - Fish tail caused by Transducer and Bogging down

[Disturbed]

Issue 1) So, this past weekend, I replaced my old cheap Humminbird that came with the boat and put a new Humminbird 788 GPS/fishfinder on. The transducer was slightly different but I mounted it in the same place as the old one. I noticed that above 35mph, I have a fishtail that sprays straight up the back of the boat and basically onto the engine at high speed.

Issue 2) This may be related to issue 1. I was cruising along doing about 35 when all of a sudden the engine severely bogged down. It sounded as though I was getting water sucked in. It would not go above 2500 RPM and 13mph. After about 20 minutes, I removed the engine cowling and checked everything. I found that the host at the very bottom of the intake had come off. I'm ASSUMING that the water spraying up from the transducer was possibly getting into that hose and sucked into the engine causing it to bog down. As soon as I reconnected the hose, away I went without a problem It then came off about an hour later, and the same scenario. The third time it came off, It had split at the end. I cut the hose to get a good connection (barely enough length left) and will be getting a new one today. Does this sound right? Water getting into that hose through the engine cow? It seemed to fix the problem each time I put the hose back on, and only at high speed when water was spraying high enough to get onto the engine.

Should I mount the tranducer lower down on the boat? Itis picking up fish fine (or appears to be), and I only lose readings at high speed. Normally we cruise at about 23-25mph.

It was an extemely calm dayout on the water (0-1ft) seas in South Florida, right off of Jensen Beach. It was almost like glass. But it was a rough day for us. Did I mention the dead battery at the start? Lmao. That was my fault. We added a 6 speaker stereo, amplifier, and fish finder, and like a dumb@$$, I never charged the battery. I just got a 2nd battery and dual battery switch to alleviate that problem in the future.

Any thoughts would be much appreciated. Sorry for the novel.
