There are three general methods of powering the Heavenly Twins:
* A single outboard in the cockpit. I do not favour this method, I have heard of people becoming unstuck in strong winds when they could not get the boat to turn into the wind.
* A single inboard engine such as a 3GM30 in the centre of the cockpit (using the outboard well) to drive twin hydraulic drives. I have heard this is a very noisy option with serious loss of power meaning a much larger engine than normal to be used, extra weight this high up is not in my opinion a great option.
* Twin inboards, my favoured method. This gives maximum manoeuvrability close quarters. It also allows redundancy, I have a few times now been able to pick up my mooring with ease when one engine has been down due to problems. This has to be a good thing, she will cruise under a single engine at around 4.0 kts, under both around 7kts. At full chat the 1GM uses approximately 1/3 gallon an hour, cruising is less still.
