2003 Montauk 170 Transducer Mounting

Can anyone give me guidance on best place to mount a transducer for a new depth finder. Are there anythings to be aware of on location and getting an accurate reading while underway?? Any input/help would be appreciated. Thanks

I have mine wired through the tunnel to the Stbd side lines where the gas ball primer and all the lines come outta the transom. It is wired though the transom well drain holes and then mounted on a bracket on stbd side just barely inside the stbd side strake. it is non intrusive and you barely notice it. It performs well at all speeds and I have no problems with the skipping or spinning etc...
I think that if you do a search you will find more info

My installation is identical to Knot at Work. The depthfinder reads bottom at all speeds from dead stop to WOT.

It is great to know that it works at all speeds.
The last boat I owned had so much air under it at cruise that the depth-finder would go to an error reading. Having no underwater eyes with a deep-vee sterndrive requires staying away from shallows, which is hard to do in bayou country. The first few trips out were a learning experience.
Because of this experience I haven't mounted a depth-finder on my 170 yet. Jim

I mounted the transducer for my Lowrance 320 on the port side, just inboard of the chine. I went with this location in case I wanted to add a kicker on the starboard side. This is the first boat that I have had no problems with speed dependant transducer problems. The sucker is rock solid. Be sure to use a ram mount for the electronics. I put the ball just behind the socket for the anchor light. I can pivot the unit 360 degrees if I want, and raise it high and angled for the times I am braced against the leaning post and making speed. Really makes a differance for me.

Jim, you won't be dissapointed! I operate in the really SHALLOW Escambia and East Bay and have hit a sand bar but thansk to my depth finder I have also avoided many!
I recommend the 188!!!
I can send you a picture if you want.. just one this time my friend!

Knot, thanks, I would like to see that picture.
Took the youngest to see Master and Commander tonight, full house. Enjoyed it. Jim

Again, I would argue against using the transom drain holes for routing cables. I elaborate on this in my article
I'll repeat a portion here:
Although it is frequently done, I do not recommend routing the cables from the tranducer through the drain holes of the motor well transom drains.
I prefer to route the cables up and over the transom. Installing them this way has these advantages:
--prevents the transom drain holes from being blocked. It is hard to imagine that people would go around recommending you reduce the size of the transom drains holes, yet people will fill them up with cables.
--gives you flexibility in relocating or servicing the transducer. If you discover the transducer doesn't work well where you initially place it, it will be much easier to reroute the cable if it is not captivated by passing through the drain.
--keeps the cable out of the lower part of the motor well. The motor well is often filled with water, thus your cables will be sitting in water. By coming over the transom you can route the cables across the transom at a height above the normal waterline of the well.
--permits plugging the drains. In some situations you may decide to plug the transom drains and keep the motor well dry with a sump pump (This is mentioned in the article on transom brackets in the Reference Section.) If the drains are full of cables you will not be able to plug them when desired.
The cables should be well secured to the transom so that in the event the transducer is struck by an underwater object it cannot fly completely free and swing on a long length of cable. It could be projected back into the boat and strike someone or become entangle with the propeller.

Jimh, valid points. I did not think about what would happen if it became unsecure, I am sure I will lose the cable if that happen.
It is actually non intrusive the way I have it mounted however it does go thru the transom drain hole.
Barney (Jim) - Master and Commander!- Awesome I love the old sailing ships of the line movies. I recall when my ship pulled into Portsmouth UK I toured the HMS Victory, and saw the very spot Lord Nelson was struck down with a Splinter from the yard arms and ball shot from a rifle. He was placed in side a rum barrel to preserve him for the trek back to UK as the ship was going to take a while to get back with all the damage.
Darned if he wasn't perfectly preserved!
