Pat, if you are set on staying with I/O power AND want 22' or less you will be limited. Many, many options in O/B power but very few in I/O because of the room the car motor takes up. On the outboard side you can now get 5 years of warranty on both Mercury 300XS and ETEC 300 G1 motors. Perfect match for one of the boats I've assembled below to both ski with the kids and to eat up LI Sound when flying solo ..............

Bernico Extreme 21 -727lbs –21’4”Long, 6’3” Beam

Chaudron Pro-S22 – 910lbs –22’2”Long, 6’2” Beam
Sutphen SSX21 - 1325lbs–20’9”Long, 7’2”Beam

If you REALLY are staying car motor, just find a clean Team Warlock 23 Offshore and prop it to ski and be done with it. I might know of a few out there.
