I own a 2003 16' Fisher bass boat with 25HP Two Stroke Merc. I have room for only two batteries, one cranking and one deep cycle.
Most of the fishing I due is on lakes and ponds, which require electric motor use only.
Question:
Can both batteries be hooked together and still operate the outboard motor and trolling motor? How? The benefit would be longer run time for my trolling motor with occasional use of outboard. :-/
