Rob, It's easy, I've done a bunch of 'em. I like to use the epoxy method as opposed to mineral oil. The only "trick" is: there can't be any air bubbles between the transducer and the water, in the hull layup or the installation.
All you need is a section of PVC pipe (I've even used plastic glasses and even a "beer cup" on my own boat) that is large enough to fit around your transducer. You can grind the pipe to the angle of the hull so it is perpendicular if you like (that's the way I do it). Now sand/grind the area of hull just down to bare glass and wipe down with acetone. Next, glue your section of pipe to the hull with some good silicone adhesive and allow to fully cure. Then suspend your transducer inside the pipe (usually by the cable) and slowly (the bubbles to be avoided) pour in the very carefully mixed epoxy (again the bubbles). Through hull transducer do loose a little sensitivity but it's on the deep end of the scale so who cares. If you are worried that your hull may have air in the layup (many do), you can always test your location by the above method, just substitute a cheap cup and filling it with water, drop in the transducer and fire it up. If it works, scrape of the temp stuff and proceed with the epoxy. BTW: The above installation will not work on a cored hull (those danged air bubbles again) Good Luck Mark, Gratis (6115) NOLA From: [email protected] [mailto:[email protected]] On Behalf Of RobAdkins Sent: Thursday, July 15, 2010 10:51 PM To: [email protected] Subject: [IC27A] In Too Deep? hi all, so my Horizon brand depth sounder has always eluded me and chooses to mock me with two horizontal dashes that seem to say ha ha you don't know if you're going aground or not. Well today i got the better of it and traced it's cable to it's point of origin only to find it isn't actually mounted to the hull but rather lying on it's side like a half dead Dorado. My question is this. can I mount it's face to the inside of the hull or must I cut and paste? Thanks -rob
