Thruhull transducer

[capt t]

I have a furuno 582 on my 33fz donzi. I have decided on the airmar 260 thruhull. anyone know what angle i need

b/c the B260 comes with a fairing block, I don't think you need to worry too much about it unless your hull angle is greater than 20 Degrees..Its not a tilted element ducer...which would require you to choose the angle..ie. 12 degrees or 18 (I think)

we are looking at the other 260 with the smaller fairing block that has the option of 12, 16, or 20 degrees

You have to measure the deadrise where the transducer will be mounted. Have you considered the B 164 which is1kw and has a tilted element. I imagine that your donzi would need the 20 degree version but check to be sure.
