There is a spot that you can get to through the small hatch in the bow...If I remember right it is indented a small amount...Normally by where the speedo sensor... Clean the paint out of the way,Then just get some adhesive and completly coat the transducer and press onto the spot..or you can google terry alsberg..and it comes up to his new business..ask him

:: Would prefer not to drill any new holes. Is there
:: anyplace on the bottom that is not cored where an in the
:: hull transducer might work?

:: Thanks
