Backing an inboard is easy. A center mounted OB would be better but the prop wash on the rudder blade can be problematic without a wheel. See also steerage way <http://en.wiktionary.org/wiki/steerageway> .
The trick is to spend as little time as possible between being motionless and having steerage way. The rudder on the C270 makes everything related to maneuvering a dream so I tend to forget I also monitor wind and current before backing. I plan the maneuver to go with what's going to happen instead of gunning it to get steerage way or being surprised and trying over react to gain control again. Since a C270 can be spun in her own length (ok 30ft +) there are times when you go with it and then do a 180 in place to head out. The problem with outboard maneuvering is I don't think you can spin the boat in its own length, which is a big disadvantage. Maybe a center mounted OB has a chance if it has handy remote controls. I'd be glad to explain how, if someone wants to give it a try. Phil Agur <http://www.catalina27.org/public_pages/profile270.htm> s/v Wing Tip C270 LE #184 MMSI 366901790
