10KVA peak for starting, 7.2KVA continuous duty for running... on sale
for $299. 120/240, single phase AC. To get 3600 RPM means to get 60 Hz.
You'll need to UP convert torque into speed at your economical cruise RPM

The price is right but it would be better if it had a speed regulated
hydraulic drive, and if it was designed for the marine environment.

For ordinary mortals with ordinary engines, high amperage alternators
and an inverter are an easier way to go, and you can use the inverter
at anchor with no engines running.
