I'll second BillyR's advice above, but if you are determined to try this you could probably get to Puget Sound on the outboard if you carry enough fuel for the longest leg, and watch the weather like your life depended on it. Once there, I would strongly recommend that before heading offshore you fix/replace the engine and go over all the systems, including rigging and sails on the boat, and learn to sail. Unlike breaking down in a car, when you are offshore in bad weather and something breaks you can't just park it and walk to the bus station. Think about it.
