We recently purchased a E30+ and need to drop and rebed the keel, it's a shoal draft. Has anyone done this on this boat? I need specifically to know the pattern of the bolts, how many etc.., as it looks like we'll have to bore into the cabin sole to gain access...? So for we can see and possibly access with a universal on an extension: two pairs in the center (4 bolts), 2 centerline bolts forward, and one centerline bolt aft? are there any others? Any info/advice on this would be greatly appreciated.
