I posted awhile back about my Tempest Plus being wobbly when spun by hand on my lower unit, turns out the darn prop is not round at the back. This "out of round" causes the prop to look like its wobbling when it is spinning. After some web "research" it turns out that this casting problem is not rare with outboard props (shame on the quality control inspectors) so my question to the prop guys on here is....Will I damage anything by using my wobbly prop? I can't feel it vibrating when the motor is running and until I spun the prop by hand I had no idea there was an issue.
