Transducer Help!

So I kicked down for a Humminbird Pirahna Max 220 for my Mainstream Kingfish.  I go to install the transducer and peak in the hull, only to realize that the bottom is angled to the middle like a boat is.  I tried mounting the transducer at the point with the shallowest angle, but it is still somewhat drastic (at least 20*).  Will this work?  Am I going to get crappy bottom/fish readings?  Short of mounting the transducer externally (which for me at least is essentially NOT an option) what can I do?   Also, since I have already gooped it, what can I do to remove and reposition it once the goop has dried?

I have already gooped it, what can I do to remove and reposition it once the goop has dried?

Put a hair dryer on the Goop for a while and slowly start to work it off. Go slowly and methodically so there's no damage to anything.

As far as repositioning goes I think you may have to bite the bullet and try to mount it in the bottom of V of your hull. You could make a foam puck from a pool noodle or kayak floatation foam and carve it to fit your hull exactly. Then put you transducer in that as close as possible to the bottom of the yak while keeping it horizontal. Then it's your call whether or not to Goop or do the water trick. I think the transducer can shoot through Goop and water equally but sure the OG's will have more insight than me on this.

I'd try it like it is first.  If you're off by 20 degrees it'll only read 6% deeper than it really is.  That's really not a big deal.  Just keep in mind that the structure or fish you see are to the right (or left) rather than straight down.

I am a huge fan of the foam puck from a pool noodle. That is the way I would go.
If you don't do it right at some time or another you will regret it.
It might be a pain in the @ss to correct it, but in the long run you will be glad you did.
Shape the bottom of the pool noodle to match your hull. When you cut the hole for your t/d
make sure it is SMALLER than your t\d. When you stick the t/d into the hole the foam will give way for the size of the t/d and this will in turn hold it in place. You will be able to angle it exactly the way you want to.

So do I just fill the foam puck with goop or what?

I assume you would goop the bottom of the puck to the yak hull, taking care to not get goop under where the transducer sits, because air bubbles in goop throw off the reading.

Got this idea from someone here:

I cut the bottom out of a small lock & lock container (from target), and goop that to the hull by its bottom edges only, all the way around, so no water will leak out from the bottom.  Then I cut a transducer-shaped cutout in a sponge that fits snugly inside the lock & lock.  I gooped the outside edges of the transducer (nowhere near the underside of the transducer), angled the transducer accounting for (offsetting) the angle of the hull, and set it in the sponge cutout as such and let it dry.  The 'ducer is gooped to the sponge now, by its edges.  Notched the lock & lock lid for the 'ducer cable access coming out of the lock & lock.

Then when i fish, i just set in the transducer/sponge, fill the lock & lock with water, clamp down the lid, and even if i flip the yak, I still have plenty of water inside the transducer container to get an accurate reading through, and the transducer never loses position, even if i get tossed launching in surf.

Plus this way I can change the transducer anytime I want - it's not glued to the hull, just the container for it is.  I'll only need a new sponge.

The Lock&Lock's are GREAT!!!they seal very well.....www.heritagemint.com.....makes a nice battery box also....Alan

I just set my transducer using the pool noodle method.  Works great.

Cut out the shape of your transducer.  Make it a snug fit.  Using a moderate amount of goop on the noodle, glue down the noodle.  It is okay if goop gets in the hole.  Place something heavy to press down the noodle assuring a good connection (water tight).  Once dry, fill with water then place your transducer as level as possible.  assuming no leaks, your good to go.

if you go the lock&lock route, here's what mine looks like...  I just fill the lock&lock with water and clamp on the top, which is notched for the 'ducer wire.  Nothing below the transducer except water and hull, with the bottom of the lock&lock cut out.   I take out the battery box after fishing by unhitching the connectors at left.  It's velcro-ed down.
