Bentoon, Echoman,
I understand your concern, and no harm in having your dealer check it out, but are either of you seeing any other symptoms of a problem? speed loss, boat listing, or a change in how the boat sits in the water?
There is a lot of space inside those strakes, and depending on where the high spot is and how large the opening for the air to escape, i could see it taking a while to get the air out.
If there is a leak, and you have used your boat several times, i would think you should see other things happening besides just the bubbles.
