Transducer Fix

A couple of weeks back I posted about transducer problems (water geyser up the transom, sealing old holes, remounting, etc...).
Thanks to lots of good advice, here is my fix:
Beforemounting, two new holes for mounting plate drilled. I used one old hole for a 3 bolt for the mounting plate:

Stainless washers & lock nuts plus nylon washers to use a spacer between aluminum hull and stainless washer.

Mounting Plate attached to hull with stainless hardware and 5200.

Transducer mounted. Tomorrow will the first day on the water, we'll see how it performs. At least now I can move it up & down without putting more holes in my transom.

Since i am used to mounting transducers in fiberglass boats i have to ask why not use a thru-hull transducer? I am wanting to mount a depth finder in my duck boat and that was my plan....
 
Are you using a thru-hull or shoot-thru mount?
Thru-hulls stick out the bottom of the hull, work great as long your are not worriedd about dragging it through the mud.



Trying to use a shoot-thru mount with an aluminum hull is a crap shoot at best. I have heard some giuys have made it work, others not.
Fiberglass is a completely different story as long as you dont have any air pockets in the glass or epoxy you mount it in.
 
Carl, Good to see you took my advise. Looks good. Although I would of liked to see you use tapered heads on the bolts so they are flush on the block. I'm all about fit, finish, and good looks. Good luck with your season.

Carl, see where the gap or hole is between the black bracket attached to the block and the transducer leg that drops down? Wrap some black electrical tape around it just above the through bolt so that the gap is closed up. It does not effect it's ability to kick up if it hits something. It will eliminate a source of the geyser.

Thanks Carl.....i was pretty sure there must be a reason why i haven't seen it done.....
 
Had to make some adjustments but the transducer is working well.
Thanks for the advice!
