Transducer Spraying Engine Solution

[Baxter]

Update:

v.1.0: Ditched the metal design for various reasons mentioned here.

v.2.0: My plastic design, copying an aftermarket solution, actually made the spray worse!!! With it, it blasted the motor, and somehow shot spray into the boat onto me!

v.3.0: Version 3 appears to work! Tested yesterday and all spray was redirected straight back. Nothing was hitting the motor. Version 3 is made from an inside corner for vinyl gutters. I then cut it up to make a sort of three sided box using a Dremmel. the top edge, and around the part where the wire comes through was siliconed as well (not shown in pic as I did it after). Cut a couple slots for the transducer mounting screws to pop through and pinch it in place.

Still a bit of a tail, but all out the back, not hitting things it shouldn't hit. My Transducer needs some adjusting still also, so going to raise it up a bit more, but at least this stops my motor from getting a bath!

Second photo is while on plane at about 50km/h. You can see the extra spray in the photo (sorta).

my transducer got torn off by a deadhead , so I sika flexed it into the hull as a short term measure and it has worked and performed well for the past 2.5 years. Glass boat though,,,,

I cut a notch in a 4" PVC cap and sika flexed to the hull to surround the transducer.
haven't tried it yet, hopefully it works.
(cost about 4 bucks)

Do you find that your pump loses prime with that water pick-up system on the left? I have something similar but my pump keeps loosing prime when we are moving with the mains

Hmm, I have never had issues with the pump. It always just works.

I had a very bad problem with spray from my Lowrance 3n1 transducer. I searched and found a company based in Australia called TIG Integrity, https://www.youtube.com/@tigintegrity . They custom make stainless steel splash guards, it was a bit expensive but worth every penny. Sorry but no after installation picture of NO splash.
