<<After two seasons of chasing down driveline vibration, the yard finally dialed the shaft and it was bent (.005"). >> "Dialing the shaft", or putting a dial indicator on the shaft and rotating the shaft to check for true running, is not difficult and should be done when aligning the engine if there is the slightest hint of a problem (hit any logs lately?). Assuming reasonable access to the transmission coupler area, (a big assumption on many boats) <30 mins should do it (when doing the alignment at the same time).

Please tell me the procedure used. .
