Your drive plate exploded. You just didnt notice it last year, probably had all winter to rust and get clanky too.
If you can support the rear of the engine while you take off the V drive, reversing gear and bell housing then sure, do it in place.
A shop with a fork truck or hoist knows they can do it faster and better by pulling the whole thinig in one big piece.
Think of it as an opportunity to service all the stuff you normally cant get to without bleeding.
Get the bilge hospital clean, new bilge pump, R&R any rusty clamps, service rudder log, shaft log, blower, tidy up any plumbing or wiring that may be adrift.
get the shop to pull it Friday and set it Monday. That gives you all weekend to clean house.
How is that for a silver lining?
