Re: Electric hybrid Inboard Vs Diesel
It sounds like you need to be able to cruise on power for moderately long distances.
That means that you'll need a generator that is sized to meet the power requirements of a ~10hp electric motor. That is about 7,500 watts minimum (assuming the motor is 100% efficient, which it won't be). That puts you into a sizeable generator. Honda only makes one that is suitable, and it weighs about 400lbs and costs $5500. A 14hp Beta Marine diesel isn't much more money (for the engine, not installation), will likely be more efficient and is much cheaper than the generator + electric motor.
Electric makes sense if you are motoring short distances most of the time and can get shore power. It doesn't really make sense (yet?) on a cruising boat from what I can see. The power consumption requirements are just too great.
