Well, I may have done something very stupid. Today I decided to clean and lubricate the cables, linkage, steering and tilt points. Without thinking, I moved the throttle control through the foward and reverse positions and to WOT. The stupid part is the shifting was done without the OB running, was repeated a few times and the prop was not manually turned either.<br /><br />How great is the possibility that I caused damage, and how can I checked that I did or did not damage something? This is a 150.
