I agree that while Volvo
did not want to take full responsibility for what many would consider a design error. They did produce the modifications mentioned. It did nothing for the splined shaft without changing the gear
set in the transmission
. Thus it is easy to see that it is possible to renew the system for $3416.66 in parts
; plus skilled labour to rebuild
box. spiral bevel gears are made in sets within the same cutter
sharpening cycle, so they are not interchangeable.
Two Companies in England
started offering a service
to grind the damaged shaft to a hexagon and made a corresponding damper plate. for this the boat
owner had to disassemble his gear box and ship the parts
away to have the work
done. then wait for the return of the parts.
I bought a 2003 engine
and spent a lot of money
restoring it before I learned about this problem. So I was motivated to find a better solution. Next Wave Marine
systems on Vancouver's Island. Canada
normally make drives for commercial
craft. I asked for help and they have developed a miniature version for the 2000 series Volvo that can be shipped to the boat
owner anywhere in the world and installed the same day using simple tools. NO Machining required.
you can watch the short video of my engine

Or get the full story from their web site. I have no business relationship with them I am Just trying to get the information out there to those who could make use of it. prevention is better than cure.
To continue the relentless thread drift, I just want to point out that the Volvo retrofit kit can be installed without removing the flywheel cover, which the rear motor
mounts are attached to, so easier to accomplish with the motor
in the boat. Just FYI.
As a means of getting back to the OP, I might mention that the Volvo propshaft seal is also pretty nice, consisting of nothing more than a rubber sleeve with multiple lips internally contacting the shaft. Simple, dripless, needs to be greased once a year. But you do have to get one specific to your shaft diameter and shaft log.
