Re: Stus-List Are original LF38 thru hulls in contact with coring?
Well that settles that, the thruhulls in the bow are not cored (under the v-berth and behind the water tank) . Solid fiberglass it looks like. Pic: (uploaded since attachments don't get through to the list): http://svviolethour.com/?attachment_id=247 Note the innermost layer is the plywood backing plate, next comes some white caulking that it was glued on with, then the hull. This pic is from before I finished cleaning all the white glue off the fiberglass. Not sure if the turquoise blue outer layer is the original gelcoat color, or a barrier coat. I was surprised, but this saves some work. The old transducer was a bear to get out (had to cut it out).

Re: Stus-List Are original LF38 thru hulls in contact with coring?
Fred, Frankly, the boat hasn’t left the slip yet this season. We practice this upcoming Saturday. So far, I’m very impressed with the display. I still need to do the calibration, but I like what I see. Well worth the effort. I removed five BG displays and replaced them with one display. I will probably need to add one more next year. They were easy to install and wire up. It sure beats the maze of wires from the analog instruments.

Re: Stus-List Are original LF38 thru hulls in contact with coring?
Patrick, I recently replaced 8 thru-hulls, 8 seacocks, and 2 transducers on my LF38. Yes, Wally’s site is a great resource. I reamed back the coring and filled with thickened epoxy. While the hull is cored with balsa, the region where the thru-hulls are is cored with marine plywood. Thankfully, removing the old thru-hulls showed dry coring, so I guess they were originally sealed well. I found two thru-hulls with threads red and very pitted, and they were likely close to failing. Removing the thru-hulls are easy with the correct tool, so I suggest that you at least check all of them.But with wet decaying backing plates, I would not wait...

Re: Stus-List Are original LF38 thru hulls in contact with coring?
I can't comment on coring but I can comment on using the right tool for the job! I invested in a step wrench and I'm glad I did. Without it, removing the old thru-hulls would have been very difficult or impossible. Even with the use of the step wrench the old thru-hulls threatened to strip, the metal was soft. My suggestion to you is wait until the fall haul out. It's been ok for 31 years it'll probably be ok for another few months. It's not a huge job or anything but don't underestimate how much time it can take .. there are *always* gotchas.
