When those mud dauber nest harden, the poster above is correct, its like drilling through concrete! Very slow going sometimes.
This is a real problem, as the water will stay pooled in the gearcase cavities, and then freeze and expand, cracking the case in the winter.
Wannabe, look for small little 1/8" holes on the outside of the case. Those are them, unless someone unknowing plugged them. Ive seen that.
