The mechanic came by this morning to do the sea trial with Dave. The repaired motor started right up. It ran 20 knots at wide open throttle. Purrs like a kitten at idle. Dave says it is a pleasure docking with two engines again. He cannot get rid of his boat grin.
Ultimately when the bill came, we expected it to be about $10 to $12K. It was $34K. WTF?!? Turns out they had mistakenly charged us both for the pump rebuild and a brand-new pump!
