I am going to install my Trim Tabs on my V-21 in a few weeks. From what I have read on this forum they create some turbulence on the sonar transducer and will scatter it's brain for a bit


. I has thinking of getting the Thru-Hull type that you epoxy to the bottom of the hull. Does anyone have some experiance with them? how well do they work problems with ect...? It sounds like the way to go to me then it also eliminate that problem and no worries about sticks or trash ripping it off. I run a lowrance sonar/gps combo.
