I recently had my Sportjet serviced (first time since owned the boat), and the mechanic removed the rear centre plug/bolt in the stator housing...

It is now leaking gearbox fluid - albeit only slighly...

First question - my understanding is that this rear centre plug/bolt need not be removed?? Only the fill plug above it.

Second question - what are my chances of repairing this - or plugging this??

Reason - the stator assemblies are around US$800 to replace!!!

Thanks in advance for any assistance
