    After the obvious cut bottom of box to fit deadrise, sand/grind/ prep hull & box.....
    Bead of 5200 to glue down & seal box to hull, glass box to the hull or both ???

    I have installed them with just 5200 and they came out great. Of coarse you need a good scribe and fit to make it right. Nothing worse than Oil leaking in your bilge.

    I also just used 5200 , no leaks and filled with the recommended antifreeze, the transducer element gets extremely HOT, make sure you have no leaks after you 5200 it down. Just an FYI. From experience.....

    I use Mineral spirits that's what Airmar suggested.

    Yes, I was working with support from them as my installation manual was in another state. :)

    Airmar changed their rec away from mineral oil to pink antifreeze years ago. Note, mineral oil will dissolve 5200 over time. Don't mix them.

    Better method is epoxy and pink antifreeze. That is airmar's current rec.

    Thoughts of using six 10 epoxy from the caulking gun cartridge?
    Prep it like you were going to glass it (grind both surfaces, wash with acetone)
    Big bead on bottom surface of plastic tank, set in place, let excess ooze out, rounder cake tool or 1 inch wide brush to shape excess, both inside & out ???
    Thoughts
    Obviously scribing/cutting tank to hull angles and deadrise is key for a good seal.
