Folks,

I want to replace the Lowrance GPS/depth finder on my boat. The depth
finder uses a thru-the-hull transducer and that will be replaced also.
The diameter of the transducer is 2". Is this a standard diameter used
by all GPS/depth finder vendors. If it's not standard, which vendors
offer transducers with 2" diameters?

Obviously I don't want to bore another hole through the hull.

Thanks . . .
