How did you seal the top of the receptacle so that the oil doesn't spill out when heeled? Lew

Epoxied a PVC threaded "receptacle" (about 3") into place and mounted the transducer in a drilled out plug. Filled with mineral oil. Has worked great for 4 years with no leaks - yet :>) Peter Z Snagglepuss #2622 -----Original Message----- From: Ralph Ahseln <[email protected]> To: [email protected] Sent: Thu, Jan 21, 2010 2:05 pm Subject: Re: [IC27A] Depth Sounder >>original message..... >From: [email protected] >Subject: [IC27A] Depth Sounder > (SNIP)>>>>>>>Considering the age of the SR sounder, I am strongly considering > just going to WM and get a new one.

That is, in most places inside the boat. There's a ton of advice about the method of Mounting an IN HULL transducer. Just do a GOOGLE for "In Hull mounting" to see them. Really, they break down into two variations.. Glued or Oil bath.. 1. GLUED:....... Epoxy or Silicone (I've heard of using Marine GOOP too).. PRO: Easy and quick to mount,... Silicone (and GOOP) relatively easy to remove (I did a silicone method, worked fine) CON: Mounting unlikely to be VERTICAL (sound cone tipped), Hull MUST be solid fiberglass-No voids,... Glued area MUST be very Clean with NO bubbles in the glue, Epoxy hard to remove. 2. Oil Bath.. Methods of mounting Numerous ! PRO: Transducer can be vertical, No worry about Voids in liquid. Oil can be any cheap light weight oil (cooking oil or Mineral oil) CON: If it leaks-MESSY!, Requires Mechanical device (Pipe or container) to hold oil and transducer, Stands High requiring Head Space,.. Once set up, difficult to move. _._,_.___ [Non-text portions of this message have been removed] [Non-text portions of this message have been removed] [Non-text portions of this message have been removed]
