I just got my boat a few months ago. Got it as a family weekender but am going to try and fish out of it a little here and there. I know its not a fishing boat but it puts me out on the water. So I picked up a little fish finder for it and put it on. I think I did an ok job but I’m not real sure if I got the angle on the transducer right. I have taken the boat out since and it seems to be working fine. Any thoughts would be great. Thanks
Well, if it’s reading anything other than 999 or some other unreasonable flashing number, it’s probably close to right. It will either work or not. If you can see land and it reads less than 100’ it’s probably right:smiley:
If you really want to know exactly, stop the boat, see what it says, lower a string with a weight to the bottom. Measure wet spot on string.

Nice to see lowrance still uses metal on transducer mounts. I bought a new Humminbird downscan and the ducer mount is cheap plastic crap. Btw, I would put something better than clear silicone on those screws…4200.
I would take it off & fill the holes. And since it’s below the water line, I would use 3M 5200 marine sealant. West Marine has small tubes of it. It takes about 72 hours for it to fully cure, but it will cure under water.

Remove the screws, pull out all the silicone, clean the area with rubbing alcohol, fill the hole with 5200 (this is below the waterline), add just enough that the 5200 will scqueeze out when you tighten the screws.
You will need to rewax the hull anywhere you use rubbing alcohol.
If you get 5200 on anything, use rubbing alcohol to get it off.
When you’ve seen and replaced as many rotten transoms as I have, you will take great care to seal the holes. You do not want water getting into that transom core! 5200 is good, but I take it a step further. I drill the holes out about twice over size and fill them with thickened epoxy. Once the epoxy cures, then I re-drill the holes on center to the correct size. This way the screws are set in a solid epoxy plug and there is no way water will ever get into the core.
I do this with every hole I put in a cored hull or deck.

quote:Laquer thinner works for me, but don't use it on painted surfaces. Ok for gel coat though.
So does mineral spirits, that’s what I usually use. Won’t hurt paint. WD40 will also clean it right up. Might be the only good thing WD40 does. I’ve heard it cures arthritis too, didn’t work for me:smiley:

I recently had to “glue” two battery boxes in the front bow cavity. I tried epoxy and some silicone… nada! flaked or came loose. 3M 5200 did the trick, used a whole tube. Beat drilling through the hull too. I keep a tube of the “fast cure” for emergencies now in my box. Great stuff. Clean your surfaces with comet, then acetone. Scuff up the surfaces. Apply and wait a day.
