TRANSDUCER PROBLEMS

[shakey55]

FRUSTRATED

I have a 2000 model Seafare V-Sea that has and I believe factory installed fish-finder and thru hull transducer.

The picture shows a thru hull transducer fitted to an old x65 lowrance unit.

I am replacing the x-65 with a Garmin 75dv

I was considering the Garmin (Airmar) B117 thru hull transducer, BUT the surface where the transducer currently sits is somewhere between 10 & 15 mm to short to accommodate the outer flange of the B117, which is 75mm.

Does anyone know if you can still get thru hull transducer similar to what I have (see below picture) that I would describe as flush or recessed.

If not any suggestions on the outer flange of the B117.

What are your thoughts on filing a few mm of each side of the outer flange (not disturbing the actual transducer face) to make it fit snug and reducing any potential drag or disturbance.

I have spoken to Garmin support about doing this and although they say it should be okay, they will not commit themselves.

I tried to find a number for Airmar support in Australia but can't seem to find one, only an American number. I wanted to talk directly to them and see what they thought/suggested.

Sorry if you don't understand what I am trying to say, but feel free to ask questions,

Information and suggestions appreciated.

Hi again,

I would of thought it is the P319. That is what i have on my Seafarer and was one of the common ones used.

I ended up keeping mine as i was in the same position as you. The new one would over hang and i didnt want that. So i have a top sounder but not using it to its full potential but i am not fussed.

You are correct about the P319. The 319 is the the same as the B117.

The P = Plastic and the B = Bronze.

Well I have decided to go with the B117, the little bit of overhang will be filed down to ensure a smooth clean fit, so hopefully no disturbance to the clean water flowing over transducer face. Fingers crossed.

Locodave what seafarer do you have ?

I had the venus first. Bought it by chance really and fell in love with it. Didnt know how good they were. That drove me to get the 6m Victory. Best boat i have owned so far.
