I have a 2003 50 hp 2 stroke Yahmaha. I have a *****ing motor mounted at the front of the boat with a stand alone deep cycle battery. I would like to charge that battery while running the engine. Is it acceptable to charge this battery using a switch and wiring so that I can select to charge either the deep cycle or the starting battery. I have had a friend tell me he was advised against this using a similar hp Mercury.
Thanks
Thanks
