It's the best boat I'ver ever owned and I've had a few,any way. The question is, I want to put a Airmar 2kw through-hull transducer in ,and obviously i want to get it as deep down into the hull / V as possible. Ive asked BW for a drawing and they have provided one but are reluctant to provide to much more info. Have any you guys done this ? Where did you put it ? How does it read at speed ? Were there any issures with hull after drilling a 90mm hole ( "3.54 inch )? Do you guys have any pictures Thanks heaps Mark (edit-fixed model name, subject ) Edited by Phil T on 04/29/20 - 6:41 AM

Having been a whaler owner for over 10 years, and a "elder" on several boating forums, here is my comment. Whaler installed a "fairing block", a thick flat pad area designed for the installation of a hull mounted transducer in some smaller cabin models. The fiberglass is ~3 inches thick. Did Whaler send you a drawing showing where the fairing block is located on your boat? To install the transducer, you need to drill a really large hole all the way through the fairing block. You need to seal the cutout hole very very well from water. It is hard to access to do the install. Owners have commented how it is a pain in the backside to do. Owners have also reported - less that great results after install. - lower boat performance. Many owners remarked that it is easier and much cheaper to install a transom mounted transducer. Less effort, less damage to the boat and easy to upgrade when the next generation of sounders is released. If, after reading this, you still want to do it, post here and I will gather the info you are looking for. Regards. P.S.

Thanks for you’re comments on users performance, but I would still like to fully explore this option. I have a tm260 transom mount tranny at present and it’s ok , but I’m changing to a chirp modle simrad soon and was very keen on through hills before . It would be great Phill if you do some more investigating for me Really appreciate anyone’s thoughts .

I will resize and add to this thread. I don't suppose Queensland Marine Centre, the only Whaler dealer down under, was any help with this? I know... they are 1,000 KM south. :-( If you want to reach out: Queensland Marine Centre Unit 10, 71 Shipper Drive Coomera Queensland 4209 Australia 61 7 5519 9035 http://qmc.com.au/boston-whaler/on-whaler/ What is the exact model of transducer you want to install? I will reach out for more info. Edited by Phil T on 04/29/20 - 5:34 PM 1992 Outrage 17 I 2019 E-TEC 90, Viper 17 2+ 2018 Load Rite Elite 18280096VT

More of a " products catch more fishermen that fishermen catch fish". Transducer mount on transom just fine BUT angle the ducer needs to mount under the boat and not parallel to the water. I would not trust a thru hull with the thin gel coat (Phil did mention specific "spots" from Whaler). You need to site aim the transom mounted transducer so your angle of vision from the bottom of the transducer clips the front bow.

Cheers Mark.
