transducer attachment

[hardee]

I have wondered about a center mounting for the transducer too. I have twin 40's on a 22 and also trim tabs. My trim tabs are mounted almost to the outboard edge of the hull, right to where the downward curve for the reverse chin starts. The space between the inboard edge of the t-tab and the transducer is only a bout 3" and the space to the starboard outboard leg is only about 6". At cruising speed (15-20 knots) there are times when I loose bottom and in most cases (bottom being 100+ feet) it is not an issue. There are times that is not the case and I have wondered about placing the t-ducer in the center. Read the instruction (to starboard) so have not don anything with it yet. Probably due some modification to the t-tabs first.

I personally like the idea of having the t-ducer placed as a shoot through, and if mine goes out, that is probably the option I will pick. (See George's shoot through mount on KerriOn).

If I was mounting one on the transom, I would consider the center mount if you have the room, (6" space as suggested in the manual instruction"). If I was starting from scratch, I would have more space between the twins,, and have longer t-tabs, (instead of wider), and I think the center mount t-ducer would be perfect.

JMHO.

I used this sternsaver kit http://www.sternsaver.com & it has worked very well for me mounted in the center between the twin Honda's. No loss of depth, but by max speed is only 21 mph.

I just installed a new sliding mount for my transducer. Purchased from: http://www.transducersaverplus.com/transducer-mount.html

Here's the down position:


Here's the up position:


Seems reasonably sturdy, but probably won't accommodate a transducer bigger or heavier than a P66. Should have it in the water in a day or two. If it falls off, you'll be the first to know.

After a couple of hours of testing, I can say the new mount works great. I get steady good readings at all speeds, right up to WOT. So far I've only run in very calm conditions. It is really nice to pull the transducer out of the water when I'm back at my berth, and that is the main reason I did this re-mount.

I do seem to have hit a sweet spot as far as location. I had no real complaints about the location of the original factory installation, although I am definitely getting better performance at higher speeds. The new location is slightly inboard of the old, but still just outside the recommended 6 inches from the prop radius. I wanted to move away from possible turbulence from the chine. I also dispensed with the wedge that the factory had used to compensate for the transom angle. I measured the transom angle at 16.5 degrees, which is just below where AirMar recommends that the wedge be used. The net result is that the trailing edge of the transducer is angled a degree or two down from the plane of the hull bottom. This may produce smoother and more consistent water flow over the face of the transducer.

Any way, so far so good.
