Adjustable Transducer Mounting / Thru Hull

 HI All, 

I have a 4.8m ali that is used predominantly for beach launching. Dry retrieve onto the trailer (i.e. skull drag up the beach away from wave surge, then wich up) and depending on swell conditions at times its a dry launch. Im currently using a 587, P66 transom mount. Given the launching / retrive i have snapped a few trannies of the transom so im chasing some info on how to stop it from happening. 

 

Firstly, thinking of going to a thru hull, however given the boat is dragged along the sand to retrive im concerned the face of the tranny will become scuffed, is this likley to affect the reading to the point where its not worth pursuing? 

 

Or, im chasing ad adjustable bracket so i can slide the tranny up while preparing to come into shore and drop it down once ive launched. The current setup where P66 'kicks up' with pressure from the undersigned works most of the time, however as i said, have also brocken a few and the $$ of replacement is adding up. Chasing a bracket Simialr to the attached image, cant for the life of me source one from anywhere. 

I do have a 200B tranny in the shed and the 50kh equivalent, designed for 'in-hull' install, is anyone aware of a bracket for those models to be converted to a transom munt?

 

Few questions i know, curious to hear any similar setups or solutions. 

 

thanks.

pretty easy to knock something up, we made one that can be pretty easily moved up and down and the pole extends above the top of the transom so your not dicking around hanging over the side.. we dont use it for beach lauching or anything but only to get a clearer sounder reading
