If you're blowing couplers, you most likely have an engine alignment problem. Alignment should be checked whenever a coupler fails. This has nothing to do with the drive you're using.

What Bowtie said.
You need to borrow mercruiser alignment tool and have someone show you how to use it. Sounds like your engine is shifting around. My coupler has been in there 12 years.
