Another vote for
South Texas Yacht Service at
Watergate Yachting Center. Mark, John and crew have always done a good job on my boats. For prop work, ask them to use
Baumann Propellers in Houston, they pick up and deliver to the yard.
If you do chose
Seabrook Marina Repair Yard, I can recommend
OJ's Marine whose offices are in the facility. O.J. handled a tricky rudder repair on one of my boats an saved me a bundle.
Good luck
