My Garmin 74sd came with a transom mount transducer. I mounted it in the lazarette by squeezing out a bed of 3M clear silicone just after of the cockpit bulkhead on the centerline. Just left the stainless hinge bracket on it. Worked fine for 6 years and counting. Saved alot of money not having to buy the internal mount X-ducer.Joe DempseyFormer Rhodes 22Trojan 42 MYDeltaville, VASent via the Samsung Galaxy S23 5G, an AT&T 5G smartphone
