Just wanted to know if this was good enough stuff.  I went to my local Hope Depot, and this was the only thing I could find that was even close to what I have seen described.  It's called LOCTITE.  It's a marine epoxy (two party) and it sets in 50 mins.  I know people say 24 hour, but there was none of that.  Is that key?  If so, I'll just have to order some from off the internet I guess.

Thanks!!

Look up 3M 5200 also sold at HD

If you want accuracy with your sonar unit, do not use any flexible adhesive to mount the transducer (3M 5200 included). You want a slow cure epoxy (24 hour). The faster curing epoxy types get lots of bubbles in them when mixed and those bubbles will absorb the sonar pulses and keep your hull from vibrating at the same frequency as the transducer.

Wayne is correct. I recommend you order epoxy from Lowrance or Hummingbird and do the job correctly with an epoxy you know is right for the job.

The transducer should be there for years, why not take the time to install it correctly.............Al

You may find some epoxy at a local bass boat dealer for a few dollars.........
