Pat, I can comment in general on this, let me know what specifics you might want.
Reliability: Good, if it has been well maintained and the cooling passages are not crudded up. Mine is RWC and the latter is currently not true - I plan to pull it this fall, disassemble it, and give it a good cleaning since it's gone beyond the capabilities of an acid flush. FWC kits are available. Spares I carry: Ignition parts (mine is still points/condenser, electronic ignition is available), RWC pump impeller and gasket, carburator jets, manual start crank (this has come in really handy and is one of the nice things about the installation in the C27 - no juice, no problem). Typical problem areas: Jets, ignition coil, thermostat, cooling passages. Speed at full throttle: Hull speed easily (call it 6.5kt), power in reserve. When I motor I'm probably at half throttle (no tach so I can't quantify). The engine's rated HP is 30 but where it operates on the curve in a C27 (no gear reduction) is about 15. Fuel consumption - about .75-1.0 GPH at cruising speed (5+kt). I've been contemplating trading the engine out for an outboard but I would really miss the reserve power. That has saved my bacon in the 'pop-up' thunderstorms that we are prone to on the Chesapeake (60kt winds and hail, anybody?). Hope that helps. Let me know what else I can tell you.
