Narrative:
I departed in moderate rain slightly obscuring visibility. I performed a soft field takeoff; and climbed to 700 where I performed my cruse checklist. At this point I noticed a lower than normal RPM indication. I then diverted to investigate on the ground. After an inspection was performed I found that one blade of the propeller was bent forward. After I found the imperfection in the aircraft I grounded the aircraft; and took another flight home. Looking back at the situation I can only assume I hit something during the takeoff.
