Garmin GT51M Transducer

Description

I removed this from a catamaran boat I purchased because it was causing the motor on the hull on which it was mounted to cavitate.  It was working at the time I removed it but I did not use it much prior to its removal.  The sale is therefore refundable for full refund with buyer paying for the return shipping or personal delivery back to Orlando, FL.  I have no reason to believe it is not working.
It is a through hull mount model and as you can see from the pictures does not include the faring block.  I assume this could be purchased separately but I would call Garmin.  They have great customer service.  It includes what is in the pictures which is the transducer, extension cable (missing tightening coupler on one end) and stainless mounting nut.
If the Buyer wants to return the item for a refund I must have it in my possession within 30 days after they receive it.
Free shipping by Seller to anywhere in United States that USPS Priority Mail ships.
Thanks for looking.
