Thanks for the response James , This deal comes with a variable speed controller. Yes Ill have to find a 220 volt 3000 watt inverter. Does 160 volt 3 hp sound doable eventually from batteries ?
You will need a 3kw inverter. And the cheaper induction motors are normally on/off full speed so it might be hard to use in close quarters, unless you drop some euro's on a variable speed controller. But sound like an interesting project, for only a thousand or so expense.

My boat is 34 feet and I only want to use this system for up to 3mph tops. Mostly 2.5 mph or less.
My boat has a Northern Lights 5 kw genset with both 110 and 220. So Im able to run off the gernerator. and would aquire a 220 volt inverter.
The dc motor will turn my 1.5 inch shaft with 20 inch prop at around 400 rpm for fishing
dc motor spins up to 1750 so at 900 rpm motor with a 3 /1 reduction my shaft should turn 300 rpm .
Im thinking to spin the shaft with a pully belt system .
I have 6 golf cart batteries used at 12 volts for the house system and for this project and would like to add solar panels and wind generator eventually .
Is this perusable in your opinion.
