new fishfinder xducer question?

1978 23 SF CC

I currently run a transom mount and dont like it (grass build up, high speed loss, etc). Does anyone know where I could do a thru hull and be safe from the trailer?

Also how is a shoot thru the hull and where can it be mounted? Drawback is that I wont have speed and temp w/ this set up.

Am I stuck w/ a transom mount again? I guess they are cheaper so Ill live w/ it.

I mounted a thru-hull Airmar on my 23' CC. You'll never go back! Search this site, there are pics, etc. mail me if you have specifics.

Eagle,

I have a thru hull on my 23 footer. Currently, it is in the water up in Raritan Bay. In the October/November timeframe I will be pulling it out and bringing it down to LBI. When it is at LBI you are more than welcome to come up and check out the thru hull setup.

Regarding the trailer question, I simply had to spread out the rollers a little so that they would not hit the through hull. Knock on wood (my head), I have not come close to hitting it yet.

I mounted my transom mount in a bed of clear boatlife right next to the keel stringer and the resolution is excellent. Granted I only fish in H2O up to about 80-100 feet, but the fish marks and bait detail on my digital raymarine have been spot on when I've been diamond jigging. I rely on the finder for a lot of my fishing. It was an experiment, but I'm happy with it and it saved me a lot of cash on the ducer and another hole in the hull.
I'm sure I'm not quite at the level of the thru-hull guys, but you might be pleasantly surprised if you shoot one through the hull of a seacraft.

You're using a regular transom mount transducer as a shoot thru hull and its working ?

Yeah-I got a great deal on my f-finder from BOE about a year and a half ago, but it came with a transom mount-I didn't feel like running it out the back so I messed around with it in the bilge-it is mounted about 5-6 feet from the stern right next to the centerline-I just got back from fishing and was marking bluefish and bait like crazy-the screen looks almost identical to the way the screen looks in simulator mode, so I think it must be getting a pretty good signal through that solid seacraft glass

Amazing- I've never heard of anyone doing that.

That is very interesting. I have a new furuno 582L and need to buy a xducer so I guess Ill buy a shoot thru the hull.

Worth a try-
I can't compare it to a thru-hull, which I'm sure would give me more res. on structure, because I haven't seen the same finder with one. If I get a chance to see one I will report back.

In mid-late 70/s I had an ancient Apelco/Raytheon flasher/recorder type on my Seafari with the sender mounted in block glued to inside of hull with silicone, about 1' fwd of transom. Worked fine as long as there was water in block between sender and hull. Have heard of the same thing being done using large PVC pipe filled with glycerin. It probably did lose some depth capability as it would not read much over 100' and it was supposed to be good for 60 fathoms. But it was fine for locating the reefs I was looking for, and more reliable than current transom mount that wants to kick up after a high speed run! Have had a tough time getting it tight enough to stop that.
