Transducer Mounted on Trim Tab?

[shallowsalt]

I have a 2005 22V and would prefer not to drill into transom.  Has anyone mounted the depth finder transducer on the bottom of the trim tab?  Is there another mounting option?

If it is a multifunction with sidescan being  so far  back the motor will interfere with the signal.

The other disadvantage is as you  use the tabs the angle of your  transducer  will change and  affect the true depth.

Do Not Mount There. Will not read accurate. Many reasons not to sorry.

Well, yes there is if you don't need the water temp readings.  When I bought my first Pathfinder, the 2000V, I had the transducer mounter INSIDE the hull.  I told the dealer that I hated the sight of the transducer hanging off the transom, throwing a tiny wake, subject to breakage, etc.

If done inside the hull, it needs to be along the center line where there is solid hull between the transducer and the water.  Plus, you need to have access to that location from inside the boat.  On the 2000V, the only area with access was above the pocket - no go there since the flow through the pocket was mixed water and air, not good for readings under way.  I asked George Lachapel at the dealership if there was solid glass under the leaning post.  "Yes, but we can't access the inside of the hull under the leaning post".  "Got a saw?" I asked. 

Here is what we did on this new boat...

Cut a hole, added an opening hatch and epoxied the transducer within a few inches of the center line over solid glass.  The transducer was a special model (Airmar P79 Smart ducer) that sat in a cylinder containing mineral oil - worked like a charm at any speed. Clean transom.  If I wanted water temp, I stuck my foot in the water.

Good luck!

Look into the stick on products such as stern mate and stern saver.  Used 2 when I remounted my transducers. They seem to work very well and depending on the boat color you might be able to get a pretty decent color match.  No holes...

You can do a thru hull mount transducer. Nothing on the transom and still get water temp. No drilling in the transom but you do have to cut a hole in the hull. Mine has been great.

Through-hull is the solution.

I guess you need to decide between a couple of tiny holes on a transom( that probably couldn’t sink a boat) or a big hole right in the hull. No brainer for me. I had a thru hull on my first pathfinder. Worked so so, but no water temp or side scan( which is really nice).

With  todays high tech units you realy need two transducers. 

The 3 in 1 can be in the pocket and allows the transom to remain clean.

The second would be a bronze thruhull with the appropriate chirp range.

The 3 in 1 in the pocket is first. When mounted properly it will read on plane.

The thruhull will have advantages and be better on plane

I have a 2004 22v and want to add a Lowrance Hooks2 Reveal with a tripleshot transducer.  It has trim tabs. Where should i locate the transducer on the transom so that sideview will be functional?  Suggestions please...buck
