Default Transducer Placement

I've had my transducer banging around loose in the bilge for too long. I can't decide whether to epoxy it down and shoot thru the hull or drill and mount it right on the keel. I know I'll lose some power shooting thru. Anyone mount a thru hull right on the centerline? I had the same unit (FCV667) on my Hydrasports and had the ducer right on the keel. Thanks

I've often wondered how it would work to mount the transducer at the keel, but always had good result by placing it shooting straight down behind the port step closest to the keel...and I mount them as far down into the water as they'll go...I used to try to put 'em just below flush w/the bottom, but couldn't get the readings at speed that puttin' them down deep gets...been there for years now and never had a problem...

I put a thru hull 20dg on mine and it always reads. I can measure it off keel to the stbd side and from the stern if you want me too.

I posted pics if you search under my name when I changed out my motor and took pics of the job.

ps I have a Furuno.

If you check under my posting when I changed out the motor in my boat it shows the thru hull installation also.

Curious...why not center it over the keel in a shoot-thru install?...what did you bed it in?...

I didn't want to take the chance on having a air bubble in the glass and so I installed this thru-hull, this ducer is a 20degree offset. I have had it in there now going on 2 years and it hasn't failed to read yet.
