Grayling's engine is not quite as noisy in real life but does not always go astern!!!! hence the bump, should be ok next year as I have a new engine in the workshop a twin this time with proper reversing!!!

Good Video.
Jack, what kind of twin are you building?
After using the twin in this tug, I'm sold on it. Easy to control as an electric motor. I was showing someone the other day, taking the cutoff lever fore and aft quickly and the engine immediately responding to every change. Smooth running and very powerful. Will propel the boat down to 5 psi.
Another thing I've learned about a twin, is the cylinder drains are not even necessary for warming through on start up. I have the two steam chest drains manifolded together with one valve venting through the side at the water line. With the cutoff lever in the middle. All that's required is open that drain valve, open the throttle a little until pure steam comes out that vent. Leave the drain open, throttle still cracked, and then using the cutoff lever, rock the engine back and forth until it spins. Let it spin slow for minute each direction, close the throttle and steam chest drains and it's ready to go. Changing directions of the engine simply expels the condensate out the exhaust.

The engine is based on the Taylor castings but very much modified.
I don't agree with your warming through system, with a twin there should be no need to ever move the engine over by hand.
You should have cylinder drains as well as chest drains.
