My advice as you have asked for...would be to sell the Yanmar boat and invest into a electric designed vessel out of the gate. Otherwise like so many major modifications you will be sending good money after bad.Blessingz has anyone swapped out their diesel yanmar engine out for an electric engine? If so where did you order it and what size does a Hunter 30 boat use. I’m doing some preliminary research online and asking experienced sailors what they would suggest. Thanks so much for your input.
