The VRO worked great and I didn't have any issues at all with it. If you want to read some forums concerning your engine, checck out www.boats.net and search for the Evinrude forums....somewhere in there they have talked about this subject.

Like Cliff, we've had no issues at all with the VRO on an '86 Evinrude 175. Runs great every year on a ski boat. Dave - 1983 Outrage 22
