My new to me boat is in the water for the season. I noticed some water in the bilge and looked to see where it was coming from. As it turns out, the hole in the transom where the transducer and spedo wire go through is not sealed well and every time the water / waves hit the hole a small amount of water leaks into the bilge. IF it were perfectly calm and the boat had no gas to weigh it down the hole would be about 1" above the waterline. Anyhow - is there a putty / plug material I can stuff in the hole for the rest of the season?
I really doubt silicone would set due to the wetness.
Any advice? Thanks!
