We went to Ensenada, Baja California to Baja Naval for a complete bottom strip, three coats of barrier coating, keel fairing and two coats of bottom paint. While I was at it, I had a PSS bellows replaced for the third time in 2700 hours, an R&D Marine (through PYI) flexible coupling and a split shaft coupling installed. I also had a new Cutlass bearing installed; good thing! The old one was pretty well done. Never replaced before. The Cutlass bearing was purchased through this site and I found the 40.5 manual was in error; the manual calls for a 3" bearing. The correct is a 4". Thanks HBO! They called it. The trip to Mexico doubles as an opportunity to have a mini vacation. The yard is also very thorough and professional; I feel comfortable with the quality of their work. I received an e-mail with photos each day on progress and/or issues. The yard had to notch the timber going under the shaft to make room for the long (and heavy) tail of the split coupler. However, it all came together quickly, ten days ahead of schedule. The flexible coupling is an experiment. It does seem to reduce the vibration somewhat although I may just be wistfully thinking. The split shaft coupling is there to reduce banging on the shaft in the future removals. Anyhow, all is well and she's good to go for a while!
