Please help with huge plume of transducer spray
« on: August 22, 2017, 09:01:39 AM »
Judging from that ugly spray of water and foam on the port side, near the motor, would you say my transducer is too high or too low?  Its's a Helix 9 mega Transducer.  This probably seems obvious to everyone, but I've never got this before.
Thanks!!

Does your Helix read depth when you are on plane?  At WOT? 
How fast can you go before you lose the DI or SI image?

I haven't hooked it up yet.  I'm assuming that the placement is way, way off, judging from that spray.  Any thoughts on whether I should start by raising or lowering the ducer?  I'd like to keep the launching and retrieving of the boat to the minimum times necessary, as I'm moored at a marina for the next few days.

It appears to me that the transducer is too low in the water. 

Adjusting transducers can be a pita.  I start by using a straight edge on the bottom of my boat to insure that the bottom of the transducer is riding just slightly below the bottom of the hull.  Potentially as important is the angle of the transducer relative to the angle of the boat at fast idle.  Here is a link to an excellent YouTube video on leveling transducers.  I had no idea how critical this was until I followed the instructions.  https://www.youtube.com/watch?v=JuYsmJRc_fE&t=10s

I have no rooster tail or water plume and my Helix SI/DI transducer reads perfectly at all speeds up to and including WOT at 50+mph.

That's awesome advice and great place to start!  Thanks for that link. Unfortunately, I didn't use the straight edge because I was in a hurry. I'll take it out and do it with more patience this time. Thanks so much for your help!
