Doing engine checks and noticed large amount of water under engine and sitting on top of sail drive. Bilges here have been previously dry. Panic thoughts of some structural failure involving deck and hull; engine or domestic water system leak, saildrive gaiter, seacocks etc Engine only just serviced...some problem here? Tasted of fresh water with subtle hint of diesel.
After much poking about noticed drip coming down rudder stock. Further investigation revealed drain hole in box compartment between two helm wheels for emergency tiller blocked with crud, from washing out cockpit. Unblock. Problem solved. Note to self "clean out emergency tiller opening/box every so often" Hope this helps someone else who may have the same problem.
