The water is down at the lake and I grounded my prop backing out of the marina. (area where they valet the dry storage). I was only idling but it did nick 1 blade and burr the edges of the other two. I didn't feel any noticable difference in the drive line but I quit at that point to replace the prop.

I have two questions - would this type of grounding have done any damage to the lower unit? Is there a way to check it out short of taking the housing off and inspecting the internals? (2) My prop had been labbed once can these minor nicks/ burrs be worked successfully? I don't believe enough material is involved to require welding (maybe just a little grinding/ polishing) but I've never had this experience with a labbed prop.

If you run solid hub props, there is always the chance for drive damage when you thump something solid. From the description of the damage, though, the odds of drive damage are small.

A local prop shop should be able to fix your props reasonably.

I boat on a lake full of prop hazards and do not run labbed props for strictly a durability issue. I do hammer out dings and file and polish edges a few times before I take em to the prop man.

Running plastic hub - whew!

I don't think you hurt anything, most of the time you need the RPM's up higher and you have to feel a vibration from a bent blade, just to make you feel better i would drain & fill the unit you already have the prop off, and look for any metal, but I don't think you will find any

luxy, I would bet you did not hurt the gears or shaft but you can do a visual on the shaft put the boat in neutral and spin it looking dead center of the shaft for any visual wobble, yes the prop can be re worked with ease. let me know if i can do the job for you. thanks , oh pop out the plastic insert to see if it has any cracks in it , this probably took most of the impact.
