At least with stern drive you can get to your drain plug . Most jet drives
don't have that option. Mine is in the center of pan about 1 in. from bottom.
Original motor had 16 years on it when I removed it , couldn't believe how
clean the pan was . Always pumped my oil out, no other choice , I would rather
remove the plug if I could . Used straight 30w oil back then and the motor had to
warm to get it out.
