Let the boat drive the prop when sailing. That shaft produces 15-25A of DC
power on Lionheart from her shaft-driven alternator. No sense wasting good
power draggin' a stalled prop behind you. Lionheart's Perkins 4-108
transmission has been freewheeling because of her shaft alternator since
1986. Doesn't seem to have hurt it a bit.

Look over in alt.binaries.pictures.sports.ocean at the engine room on
Lionheart under the center cockpit. The shaft alternator is driven by a
flat belt from a large pulley on the shaft. At 8 knots, the special
alternator, itself, is turning about 200 RPM. To get the engine started,
you must turn off the excitation current to this shaft alternator so you
can remove the keyring from its switch to move the keyring to the engine
control panel to crank the diesel. This makes sure you have secured the
shaft alternator before starting the engine....captain proof.
