Hey Bones, My first thought was to try heat also. When installing the transducer is my boat I had some trouble finding a good location. In the end I decided to epoxy it to the hull and if the location was wrong I planned to heat it to remove it. 5200 is tough, but I think heat gun heat, as opposed to a flame would be helpful. Knowing you, I guess you've already thought through this logic. Let me know what works. Rick M15 #337 Bluebird

Hello Listers,

I have purchased new instruments for my M23 and after hauling out this fall I intend to mount the new mushroom transducer housings in the same spots as the present ones. The question: does anyone have any experience removing the old mounts? I have no idea what adhesive was used to glue them into the hull, it could be something as strong as 3M 5200. I was thinking of removing the clamping nut, then applying some heat to see if the mounts may loosen. Then do some gentle prying. Any input would be appreciated. I purchased new Navman speed and depth electronics to replace the old Signet Marine.

Thanks,

Bones in Mpls
