thought I would close out this thread
there are a few write ups on iboats :

as well as the PDF posted by Don S "Here is a pdf file on how to replace the flywheel housing bearings.
Overhauling the Flywheel Cover.pdf "
Since I dont like to press anything anymore, I prefer to thermal-press (heat one item, freeze the other)
Tools needed: double-x snap ring pliers (you can try it with a long needle-nose, however after swearing a lot, you will simply buy the right tool off of Amazon and have delivered in 2 days
1/2" diameter brass drift
ball-peen hammer
brake cleaner
2 beers
Removal:
drive a 1/4" lag bolt in each seal and pry out
use snap ring pliers and remove all 3 large diameter snap rings
from input side, use ball-peen and drift, drive the shaft and one bearing out the output end
once the shaft and bearing are out, remove the external snap ring and remove bearing from shaft. I used an arbor press
use drift to drive input side bearing out of PDS housing
clean up snap rings with brake cleaner
clean up shaft with brake cleaner, inspect for damage, wear, pitting, cracking etc. notice that I found a crack that went 3/4 way around shaft - buy new shaft if needed, yes they are pricey
clean up housing
optional - repaint as needed. I used ford Red first time, Autoparts store didnt have it this last time, so I used red caliper paint - same color as ford red
have first beer - enjoy as paint dries
re-assembly
Sequence is input side bearing goes in housing first (freeze bearing, heat pds housing). I put the bearing in the freezer for about 20 minutes while I propped up my heat gun to blow inside the PDS housing from the output side to the input side. Also have the shaft in the freezer at this point as well.
retrieve bearing from freezer, drop bearing in heated PDS housing, then add snap ring.
heat output end bearing with heat gun. I hung it with a bit of mechanics wire above the heat gun. retrieve the shaft from freezer and with gloves, grab the output end bearing put on shaft (it should just drop on ). Then install shaft snap ring.
return whole bearing/shaft/snapring to freezer - grab another beer
prop the heat gun to heat up the output end of the PDS shaft and the input bearing you will be heating the housing to about 200, shaft will be at 0, it will drop in - no fuss - no muss
Add both snap rings.
Pump in grease while rotating shaft until you see grease coming thru bearings, keep pumping a bit
coat outer OD of seal with permatex #3 and Drive in seals. - I used a piece of PVC pipe
pump in more grease until you get a bit out the output shaft seal
Reinstall pds housing, reinstall motor, reinstall drive - or wrap in plastic and put on the shelf like I did as I am awaiting the motor from the machine shop
