Ate a rock at the end of the season. Tried for a couple of hours to dislodge it, finally gave up. Final bill, out the door, parts and labor, tax and fees:
$974.90
My ass still hurts. Rule #1, watch for shallow water!
I have the impeller, wear ring, and the " $1000 rock " in a shadow box in the garage by my boat as a reminder!
