I had a prop strike in soft ground at Peterlee in C182Q whilst taxying.
Minor damage to outer 1cm of prop tips,engine did not stop
Required shock load inspection and new prop/hub
Engine only had 200 hours so cannot comment on whether to overhaul your engine
Fitted 3-blade prop - much better ground clearance and I think better performance (also looks cool!)
Insurance company were excellent. New 3 blade prop was actually cheaper than 2 blade(?!) and because original prop/engine had only 200 hours there was little 'betterment' to pay
As I was 150 miles from base you learn the importance of having a good working relationship with your maintenance organisation - mine had the engine out within 24 hours of the incident (plus all the avionics as a precaution!) The insurance company were not prepared to cover the cost of derigging and transporting to home airfield.
Talking to C182 owners with 2-blade props there seems to be those who have had a prop strike and those who are going to have one!!
Safe flying
