well i am giving up on getting the rusty shaft out of the coupler and I am about to take a saw to it cause I am ready to get the motor out. Does anybody have or know where I can get a driveshaft to replace the one I am about to cut in half. Need to know what kind of $$$ I am looking at for this thing. Its a 1990 boat and it looks like and Alpha ONe or an MR drive with a 4.3 engine. Also need the coupler to go along with it. THanks.
