I own hull #372 (recently purchased) with ~1000 hours on my Yanmar 4JHE. I just replaced the cutlass bearing (which was in bad shape). The yard told me they completed the job in 30 minutes (incidently, the yard who hauled me for the survey told me that they would likely need to remove the rudder - happy to say , I did not use that yard!). Sorry I cannot help you with the dimensions.
