Hi everyone,<br /><br />I was reading this board and I found a lot of good information, however I still had a few questions that I was hoping someone could answer.<br /><br />I have a larson 2005 SEI 180 SKI I/O, and was looking to put a depth finder on, but I need more information.<br /><br />1) Can you use a transom mount on an inboard engine without too much turbulent interference?<br /><br />2) Can you use a transom mount transducer as a shoot thru hull transducer, or do you have to buy the seperate one?<br /><br />3) My boat has a Delta VEC hull, will a shoot thru hull transducer work on this type of hull?<br /><br />4) Does a shoot thru hull mount have to be in water, such as in the bilge, or can it be dry?<br /><br /><br />Thanks in advance, I look forward to all you input. - Erick
<br /><br />Transducers work best when they are rigidly mounted with their acoustic window in clean water. (clean = no bubbles, turbulence, or debris in the water) Both transom mounted and thru-hull ducers allow for those conditions. Obviously, a transom mounted ducer needs careful placement to get clean water. In-hull mounted transducers are acoustically coupled with the boats hull to shoot through the hull material. The in-hull mounted ducers operate dry. If you operate a typical transom mount or thru hull mount ducer with the acoustic window out of water for more than (something like) 60-secs you can damage the transducer. It depends on the resistance the water creates to keep the internal ceramic from cracking. You can mount such a ducer in an oil filled well inside of the bilge and it will function as an in-hull transducer. In general, the performance or efficiency of in-hull ducers isnt up there with thru-hull or transom mounted, but the diff isnt likely to matter to most of us.
