Battery in not be charged back . Looking for a new regulator . The 2006 year needs part number 31750-zw-F92 , but they look to be on backorder everywhere and have been waiting over a month and a half. In 2007 they changed to a different regulator 31750-zw4-003 and this is also used on the 40hp. My question is dos anyone know if the regulator for the 2007 model will work ok in my older 2006 model ?
