FellowShip,
We ended up with (12) 2" dia. holes (3 in the liner and 9 in the hull) to drain the water and remove soaked foam. We left the heater and a fan blasting for 24 hours and I feel confident that the worst of the "intrusion" has been eradicated.
I'll be following Boston Whalers’ directions for re-foaming the hull and glassing the holes back in after the short curing time.
I wish to extend thanks and credit the excellent information provided by
Continuous Wave.
