OK, Here it is from the lead line specialist. There was an article in December SAIL magazine ' SOUNDER ROUNDUP '08. They tested sounders an transducers. It was brought out that impedance has to be matched between the transducer and the sounder to get the best readings. M-A-R-K twain, Kathy

[> [> [> Final note on Thru-Hulls -- Lyle Harris, - Tuesday - 03/10/09 - 1:14pm

Follow-up to how many thru-hulls below the waterline on an M31... I'd originally thought there would be three thru-hulls below the waterline to replace. Turns out there were six. I'm fairly certain this was the original configuration for the M31. There are three in the Head, and three in cockpit area.
The cockpit drains and head (toilet)drain are all 1.5 inch size. The toilet saltwater intake and head sink intake are 3/4 inch, and the engine raw-water intake is 1 inch. All thru-hulls were mushroom-flanged bronze.
I suppose it could be different for other boats, but this is what I found.
