Dave - And just to let you know, the two-side method worked beautifully.  Did 
it yesterday.  Thanks to all who responded (and with a single solution!).

Oops - sorry frank, another too hasty reply from work...Agreed with other 
poster, drill from both sides.  As suggested, Good practice to score one side 
first anyway to prevent splintering.

A question about removing a depth transducer to install the new one.  Based on 
earlier input from the list, I have used a 2 inch hole saw from the top. 
Fortunately the diameter of the old transducer is just shy of 2 in and the new 
one requires a 2 in hole. So the body of the old transducer just fits inside 
the hole saw, keeping it lined up with little drag (not cutting much of the 
plastic body of the transducer).  When the inside top of the hole saw reached 
the top of the transducer, I then cut off the top half of the transducer so I 
could proceed drilling down.  Now the hole saw just touches the hull, but the 
inside top of the hole saw hits the top of the transducer, so I will need to 
saw off the next section of the transducer to proceed further.  With my tools, 
not so easy to saw off the transducer just above the hull. Question: what about 
drilling down thru the transducer with a regular drill bit, using the pilot 
hole made by the drill bit in the hole saw, and then, using that hole as a 
guide, use the hole saw to proceed up from the outside of the hull.  This would 
avoid cutting thru more of the transducer (a pain), and the pilot hole should 
guide the hole saw. Sound OK, or better to continue from the top?Thanks as

I did mine with a 2" holesaw, completely from the outside and was done

Re: Stus-List depth transducer replacement

[Dennis C. via CnC-List]

I frequently drill from both sides when using a hole saw when I want a clean 
hole on each side.  When you drill from one side you risk splintering on the 
exit side. Sodo it!
