Thanks for the video. I installed my b117 through Hull on my 97 sea cat sl1 a couple of weeks ago. I followed your steps exactly with no problems minus the extreme anxiety that comes with drilling a 2 inch hole in the bottom of your boat!
Nice video @FishonForte! Thank you. I’m about to install an SS75H and am petrified to drill a hole in my hull. Much more confident having watched you do it. Thanks again.
I bought nickel-sized magnets from Home Depot. They stuck to each other through more than 3/4" glass. This is a great tool to precisely locate the pilot hole.
I'm curious as to why you didn't remove the core around the hole after you drilled it? Whenever I install a through hull with a cored Hull I use a finish nail or wire Brad chucked in a cordless and bent at a 90 degree angle to remove 3/8 "of the core material. I fill this area with thickened epoxy (silica) and let it sit for a day before proceeding. Doing this ensures that no condensation will ever touch the core and it also strengthens the area that you drill out. You did a nice clean installation. A lot of people figure the more 4200 the better off they are. Adding gobs of the stuff just makes for a messy install and actually increases the likelihood of a leak. It's also important not to over tighten the interior nut or backing plate.
@@davidlofberg9792 Thanks for watching. I can hardly believe it has been almost four years since I made that video. I have not had any issues with the transducer or water intrusion.
It looks like this video is 4 years old. Can you tell me how this transducer performs? What I have trouble with is losing my fish finder when I am underway. I can maybe do 3 or 4 mph then I lose it. I have a transom mount transducer and am wondering how the through hull works.
The transducer has been great. If you look at some of my newer videos, since I put in the Simrad MFDs, you should be able to see how well it holds bottom at speed in some choppy seas. Thanks for watching.
dave radford Thanks for watching. You can use either one below the waterline. However, it will be hard to remove the transducer if it fails if you use 5200.
I can’t recall but it differs depending on the transducer. If you get a through hull transducer, the hole saw size will be included in the instructions.
