My first terrova was a 54 inch shaft. Cut 8 inches out of shaft which I liked a lot better. Just installed a new ulterra with a 45 inch shaft. These were on a 361 ranger. loved the shorter length on the terrova but have not tryed the ulterra yet. One word of advice if you ae pulling boat with a cover on I would mount motor to a removable plate as cover does not fit good over terrova. Takes 30 seconds to remove my motor and then put cover on.
