So after spending an enormous time digging, I've decided to come and ask for input.
I am looking at the feasibility of replacing a Lehman Diesel
(~85-90HP) with an electric motor
on a sailboat (~55', ~54,000lb displacement).
Before we go too far, I know it is an unpopular idea. I'm not interested in hearing how difficult or not-feasible this is with batteries
etc.... I am interested in making an off-grid, green, live aboard and willing to sacrifice speed and convenience for that effort.
More importantly, I am not interested in reaching Hull speed
(7-8kts for my boat). More like max of 4kts is what i am thinking and even that i'm willing to reduce further.
If i try and do a HP for HP sub to electric
, i'm looking at something like 40-50kW electric motor
which has been difficult for me to find in the BLDC realm.
I'm curious about Motenergy ME1115 or similarly sized motors and how undersized a 15kW to 30kW max. I've also been considering something like Motenergy ME1002 (https://www.electricmotorsport.com/e...ors/sm300.html
I'm also curious about peoples recommendations on a bigger electric motor
and where to find one for my application.
