If the transom board does not go all they way to the keel bee sure to use thru bolts with nylock nuts. 3M 5200 for a sealer.

If the boat does not already have a lot of holes drilled in it <br />then I would mount on one of the white mounting boards. <br />This way you do not have to drill many hole in the boat. <br />As time passes you add a speed sensor or get a different <br />depth finder that had different mounting holes. <br />With the mounting board it no big deal to drill a new whole in that white board. <br />For me hard to drill a whole in the boat. The way I did mine I used the board and did not drill any new wholes. <br />I put some silcone seal on the back of the board. Took out the screws that held the <br />speed pitot and the drain plug and put in some longer ones in the same holes. <br />Put a washer and sealer on the inside and board is solid for mounting anything.<br /><br />The sell the boards here at IBoat also but could not find the link.<br /><br /><br />http://www.cabelas.com/cabelas/en/templates/links/link.jsp?id=0000847010102a&type=product&cmCat=search&returnString=_dyncharset=ISO-8859-1&hasJS=true&_D%3AhasJS=+&%2Fcabelas%2Fcomm erce%2FCabelasCatalogNumberFinder.giftCertificateURL=%2Fcabelas%2Fen%2Ftemplates%2Fgiftcertificate%2Fgiftcertificate.jsp%3Fid%3D0005586990011a%26podId%3D0005586%26catalogCode%3DIB% 26navAction%3Djump%26indexId%3D&_D%3A%2Fcabelas%2Fcommerce%2FCabelasCatalogNumberFinder.giftCertificateURL=+&QueryText=Mounting+Plate&_DARGS=%2Fcabelas%2Fen%2Fcommon%2Fsearch%2Fsea rch-box.jsp.form9&Go.x=10&Go.y=12&N=4887&Ntk=Products&Ntx=mode+matchall&Nty=1&Ntt=Mounting+Plate&noImage=0&returnPage=search-results1.jsp

Re: Best way to mount transducer

We did a similar install on a SeaArk. I made a plate out of some plastic at work we used in a display. Might even be the same stuff Boatist is talking about... but I just adhered it to the transom, didn't use existing holes. I mounted the transducer with stainless screws making sure they weren't so long as to go through the plastic plate. The plate was 4x4x1/2". Been there for four years with no problems.<br /><br /><br />spots
