I recommend that you go get a service manual and study that. There are too many 'rubber' part for me to guess how many.
Goto your local dealer, have them pull up schematic/parts list and start ordering.
I pulled the outdrive on our boat last spring and started replacing items that needed it. The bill runs up very fast, I did not replace everything, only what I deemed necessary, and I will keep an I on the hoses that did not get replaced (ones on the motor itself).
