I have a 10,000 lb. boat with dual Volvo outdrives that are 1.89/1 with 14 by 15 props.
Would electric motors work here?
Yes. Jack Knopf in Texas has built this yacht conversion with a 12 HP electric motor using 72v or so. He says acceleration is "slow", but his boat is considerably bigger than yours (20K lbs.), and he's apparently only got one motor.
