I have the Xpress HD20 with a 200 SHO. You could put a 115 on it and rig it for crappie and it would be great. Really good ride and I fish mostly in that little 186,000 acre lake Toledo Bend. I would recommend no carpet for crappie fishing. Mine is carpeted on the decks, but not the floor. BRM may correct me, but it should go 45 with the 115, maybe 51 with a 150.
