Hi. I have a 1995 9.9 model E10EEOE and s/n G03741017. It is e-start and has cables to connect to battery. Can I run this safely without connecting a battery? What do I do with the pos and neg ends of the cables? Will this do any damage to the charging system? Thanks. By the way, is this outboard worth much on the market? I really don't need it and it is in extremely good condition - powerhead looks like new.
