We have an Ensign at a dock. It used to be at a mooring but for various reasons we have switched to a dock. To get to the ocean to sail, we need to thread a fairly narrow channel of maybe 100 yards. with rocks on the sides. We need a reliable motor to do so. We have an electric motor but it has proven unreliable and underpowered if there is some wind / current. Any advice on an outboard motor in the 3-6 HP range, with a long shaft, that would work for an Ensign? The electric motor is maybe 20 years old so maybe there are better ones available now. But a gasoline outboard could also be possible. Advice welcome. Thanks you.
