I would like to install a shoot through transducer in my 2001 230 Select, Sea Ray advises against it stating "You cannot install that type of transducer because your boat actually has a liner in it, not a solid fiberglass hull.".

Does this sound accurate? Seems a bit strange to me.

Anyone else ever install a shoot through transducer in a similar vintage Select?

Cheers,
Tom
 
Examine other existing thru hulls on your boat to gauge the thickness. My hull has both cored and solid sections.

Did you talk directly with Sea Ray or a Dealer? IMHO - If it was the Sea Ray factory that pretty much answer your question.
 
If your boat doesn't have a solid core then you need to go to thru hull. Not that hard to do but a killer on the nerves, it does goes against a boater's grain to drill through the boat bottom. Good Luck :wow:
 
Tom,

There's a post here somewhere with a picture of a shoot through transducer in the bilge of a sea ray. The poster says that it works great. I think it was a 260 ... not your exact model boat. I've been searching for it myself... I'll let you know when I find it.

Yes.

If an existing thru hull exists, then measurements on that existing thru hull would permit determination of the thickness at that point.

The interior and exterior contours from that known thickness permit estimation of thickness at nearby points.

Symmetry permits estimating the thickness on the opposite side.
 
I had a transducer intended to be transom mounted, attached to the inside of the hull. I used marine tex epoxy and just stuck it opposite the factory depth finder transducer. This was on a 2001 260 select bowrider. Worked fine.

Buy or borrow a fishfinder from you local marine store, hook it up temporarily and just hold the transducer down with duct tape or a sand bag. See if it works. Come to NH and borrow mine, I took it out when I sold the boat.
 
I have the transom mount transducer that came with my Garmin 545s, I'll give it a try. How will I know it's working correctly?
 
I recently got a Humminbird Matrix 47 3D sonar. The instructions were quite clear and easy to understand about mounting it as a "shoot through' transducer. Pretty easy but you do need to have it on the water. They stated that you have to use a coffee can, or similar device to purge all air from the mount site. (Seal with clay or caulking and fill it with water at the intended location)

If there is no air at the location, or air in the lamination of the glass, it should work fine.

Check the humminbird site for an idea. Use the model I bought since it's one of the more intricate t-ducers. Matrix 3D.

If you want to test locations in teh bilge you will need to put the ducer in a big ziplock bag or small trash bag full of water, then you can move it around the bilge until it works. If you have a linered bilge then you can't use a shoot through. There can be no air or bubbles or voids between the ducer and the water. A linered bilge has a void between the bilge and hull.
 
Nope, the bag works fine. One of those things you learn after you've installed about a dozen of these things. Unless somebody tells you before you install your first. Got to love the internet.
