This is the only 2nd time I've had my boat out... and I hit something underwater..it took about 1 inch off each blade on my prop and took just a little of the skeg off luckily I was only going about 10mph and I don't think I damaged anything else the prop shaft doesn't wobble or have any play only thing I noticed was some vibration but could the unbalanced prop cause this?..I sure am glad I didn't have a stainless steel prop probably would have bent my shaft ..atleast the aluminum shaved off clean.
There is a reason for all those prop shops to be in business. Yes the wrecked prop will certainly cause "Bad Vibrations" so please don't run it as you can cause much more damage to the lower unit. Take it in to a prop shop for repair (it's pretty amazing what a good shop can do) or pick yourself up a new one and keep the repaired one for a spare.
