noticed on the gear drives website about their prsu that replaces the eggenfeller that they have a centrifugal clutch which essentially looks like an automotive clutch disk, has a pressure plate and some sort of springs and fingers of their own design. Supposedly to help with the vibration and harmonics, and allow the engine and drive to spin down and eliminate the shudder of the prop trying to turn the engine over as it winds down.

so my thoughts is a similar design but using a production made cast aluminum bellhousing meant for putting a subaru engine into a vw with a vw transaxle. This would allow me to run a standard subaru starter, flywheel, and a high performance clutch to handle the load while having torsional isolation and the ability to hydraulically disengage the engine from the drive during engine start up and or shut down.
this bellhousing would also serve as the adapter for a planetary style prsu like the real world solutions or a marcote drive.

also in theory if there was ever a grounding or a prop strike the engine might be saved because of the clutch disk being able to slip a little.

most may be thinking wha if the clutch hydraulic system fails, well in a failure just wouldn't be able to disengage the engine from the drive.
any info or insight is appreciated. just looking at getting a descent prsu and an relatively easy way to adapt it to a subaru without spending 5-7k$ in the process.
