21 Contender / Yamaha F250?

anyone have any experience with the above? I’m considering repowering my 2005 21 Contender from a 200HPDI to a 2010 Yam 250 4stroke.

200HPDI is 475#
F250 is 562#

remove 3 gal oil tank in stern and save approx 27# (full), leaving total weight difference approx 60#.

Any performance #'s, fuel #'s, adjustments?
