I need to replace the original...

I need to replace the original transducer on my 2001 380DA. I have new MFD's (Garmin) with sonar capability and would like to choose a transducer with temp, depth and sonar capability. Am looking for a thru-hull, flush mount transducer. The boats original spec sheet indicates the boat has a 19.5 degree deadrise. Does that 19.5 degrees deadrise apply to where the existing transducer is located - just off the centerline to starboard in the forward ER bilge? Any recommendations on a suitable transducer?  Thanks.

Go to Bam Marine. Located in Florida. They have the transducer.

That deadrise spec is at the transom. The GT51TH or GT51THP seems to be the best that Garmin has to offer. If there is a B275LHW option that is compatible with your displays, that is a good transducer that will read down to ~1500 ft reliably.
