Looking for anyone that has experienced this issue.
I've included a link to three photos below and a video. Long story short, on the interior of the transom right to the outside of each stringer, I've got a small hole that weeps water. It's about the same spot on both sides. I've had the boat hauled twice now. Removed, re-glassed and then reinstalled, rebedded the trim tabs and actuators, the transom sonar, the zinc plate, etc. All to no avail.
On a cruise over the weekend, following the last haul out, I filled the bilge with freshwater as a result of a yard worker knocking the water heater connection loose.
If you look at the video, you will see bubbles rising from one of those holes on the port side. I initially thought the boat was sinking. However, after tasting the water and checking the water tank level, I realized it was a freshwater leak. So where are the bubbles coming from?? The answer is exhaust. When I turned off the port engine, the bubbles stopped. Turned it back on and the bubbles started.
Best I can figure, one or more of the screws holding on the underwater exhaust ports is leaking into the fiberglass. The water, of course, runs downhill toward the transom and weeps out of the two areas. When the engines are running, the water is replaced by exhaust gas.
I'm moving toward a THIRD haul out to remove the exhaust ports, grind, glass and rebed them.
Before I do that, however, has ANYONE had a similar problem? This has been a 2 year trek to get a dry bilge and figure out where this water is coming from. I feel like this freshwater leak was a fortuitous event, as I would never have seen the exhaust bubbles.
