drive shaft splines

[wayneo99]

following my incedent with the mooring chain and my lower unit I dropped the LU and the splines on the drive shaft look at little tweaked. not really twisted just a little gouged on one side. The unit came off with ease no binding.

Motor seems to run well, is there more to this situation or can I simply purchase a new LU and install as when I do my bi yearly water pump changes.

Rodbolt any suggestions? or issues that I may encounter in which I should by pass the DIY and let the dealer do the work.

thank you

here are few few pics.

Re: drive shaft splines

well, just looking at the lower about all that comes to mind is that its some type of V4 or 2.6L V6, lack of a shiny spot above the pump shaft usually indicates its a 20" shaft or the bushing is missing from the midsection.
splines look like normal wear if its not been greased yearly with spline grease.
lower case doesnt look trashed, I would dissasemble it and look for any internal damage, the case only shows some cosmetic damage.
I would also pop the flywheel and inspect the flywheel key.
but its very difficult to make educated guess's when one of us is clueless about whats actually being worked on

prop looks to be repairable by a competent prop shop.
used prop shafts are readily avalible and easy to check with V blocks and a dial indicator, in fact unless its really really bent its about the only way.
