1. Transducer problem
Recently purchased a 1997 26 foot Shamrock and we've had problems with its depth finder/fish finder. We've found that the original owner installed a transome mounted transducer which we understand is not compatable with the inboard motor. We would like to upgrade to a Garmin 160 or a Garmin 240 with either a shoot-through transducer or a through-mount transducer. I would like some feedback on the pros and cons of each and also what would be the best location for the transducer on this boat. Any information would be greatly appreciated.

I HAVE HAD 3 SHAMROCKS AND REALLY YOU SHOULD GO WITH A THRU HULL IN FRONT OF THE SEACOCK. AND JUST GO AHEAD AND SPEND THE MONEY AND GET A FURUNO YOU WON'T BE DISAPPOINTED!
HAPPY SHAMROCKING.

I had a 20 pilot house and used a Furuno LS 6000 with a bronze through hull tri-ducer for 5 years. For a inexpensive price the unit performed great. The new 582L or the 1650/1850 chart plotters are great. Buy a lot of output power, watts RMS. And use a through hull, not a shoot through the hull. Don't be afraid to cut a hole in the bottom, that is what 5200 was made for. Good luck. Bob.

Hiya,
On my 246 WA, I initially installed a transom mt in what I thought was a location clear of turbulence. Worked great for trolling but no dice at speed. After some research and considerable experimentation, I epoxied it inside the hull to shoot through the hull and it operates super...I see no degradation in accuracy or range. I didn't want a through hull because I trailer a lot. Another consideration is the type of transducer, if it has a built speedo/temp sensors (triducer?), you can't do an inside the hull mount. If you want to try inside the hull, check with the unit manufacturer for installation instructions and follow them religiously. I can also give you some tips if you want. Good luck and save some fish for the rest of us!

IF YOU GO WITH A THRU HULL MAKE SURE YOU MOUNT IT IN FRONT OF THE SEA COCK OR YOU WILL HAVE THE SAME PROBLEM. BUT IF PUT IN RIGHT YOU WILL GET FAR BETTER RESULTS THAN ANY OTHER TRANSDUCER.

I have two depth finders on my 26. One is a through hull dual frequency for my Furuno, the other is a shoot through hull for my Lowrance x85. It was very easy to install. I located it just to the starboard side in the flater area adjacent to the shaft (make sure there aren't any other through hulls to impede the flow of the water forward of the epoxy mount) you may want to try this in a bucket of water to make sure you are in a good part of the hull for maxium efeciency. Make a damn out of plumbers putty then slowly mix a good two part fast setting epoxy (you can't have any air bubbles) pour the epoxy in the mold add the transducer and gently rotate to remove any traped air make sure that the transducer is level, hold in position for a few minutes (the fast set epoxy sets up tacky in just a few minutes) afterwards place something fairly heavy say 3 t0 4 pounds on tip of the transducer and let dry overnight. My Lowrance will work at any speed and shoots to a depth of 800 to 900 feet without any degragation of signal. After that is does lose the bottom. It operates up to about 75% of its listed range. Good luck

YOU WILL NEED TO USE A FAIRING BLOCK TO MAKE THE TRANSDUCER TIGHTEN DOWN TO THE HULL AS FAR AS PLACEMENT I WOULD PUT IT JUST FAR ENOUGH IN FROT OF THE SEA COCK TO PREVENT ANY BUBBLES OR TURBULANCE FROM GOING OVER THE TRANSDUCER 2" SHOULD BE ENOUGH. ALSO CUT YOUR FAIRING BLOCK AT THE CORRECT ANGLE TO MAKE THE TRANSDUCER POINT STRAIGHT DOWN THIS WILL MAKE A BIG DIFFERENCE WHEN FISHING IN DEEP WATER. YOU CAN USE A PIECE MAHOGANY FOR A FAIRING BLOCK ANY BOAT YARD SHOULD HAVE A SCRAP PIECE.

I have poly fairing blocks inside and out on my 246 W/A with thru-hull. I am not sure where they came from as the unit was dealer installed. Worth checking out versus the wood.

Make sure you use slow cure and not fast cure epoxy. This allows more time for the bubbles to escape. The bubbles are what will kill ya.

You already have lots of good info. Here is a trick the Humminbird factory gave me. To find a good location for an inside the hull installation put some water in a ziploc bag. Put the transducer in the bag and seal to extent possible. Connect the thing and you can move the bag around while operating to find good location. I did this on a 38' Carver My and was so pleased I just left it that way. If keeping it in one spot is a problem just lay another bag filled with sand on top. Neat Huh?

Heres another way , I got a piece of 6in diameter plastic drain pipe from blackman plumbing and also a pipe cap. i cut appx. 3 in on the high side and 4in on the low side..this is an angle cut that installs directly to the hull by way of boatlife sealer not 5200....now i drill a hole in the cap and sandwich the 2 flange nuts to the pipe cap useing boatlife.. now i fill the pipe 3/4 full with mineral oil and adjust the transducer on the cap so as the ducer does not touch the hull it just sits suspended in the oil and what a great picture i get at any speed and a great wreck finder this f/f i have is a humm wide view about 450 bux with a bronze thru hull but i also just bought the sitex cvs106mkII color machine with a through hull triducer and that is through the hull directly behind the hummingbird...my location for these on my 20 ftr. is 12in to the stbd side of the keel just an inch or so in front of the shaft coupling.it does get in the way of the rollers but i float the boat on the trailer anyway thats all i got for now p.s. DO NOT USE 5200 ON ANY THRU HULL FITTINGS ITS TOO PERMANENT LOVE THIS SITE GAVIN THANX MATEYS
