CLANG! I hit my boatlift- DF140 now leaking…

Yes- I win the “Admiral Award” for seamanship- I hit the leg of my lift with my port motor while departing the dock- I swear it was the wind(twin Suzuki DF140). Engine stalled, I lifted it and inspected- 1″ divot in horizontal fin above prop, prop no damage. I restarted- ran fine, went out for a 1 hour cruise. I noticed oil sheen in water around motor upon return while idling at the dock, shut it down, lifted boat- no obvious leak. Now I see oil sheen when flushing motor with flush kit- seems to come from pop /hub area, not pee hole. What have I done?
