Driveshaft removal...
gonna have to remove the pump, inwhich, disconnecting the water inlet tubes inside, above the shaft assy, then removing the pump, might be able to make a jig to pull the pump as even as possible, and not break the stems that run into the hull, from there loosen up clamps from around the drive assy( this is under the grey cover inside hull), probly spray penetrating lube at bearings, then pull on axle.
