Force 50, how large/what type battery should i need

[smithsmarina@gmail.com]

I have a 700 CCA deep cycle marine gel cell that will not turn the engine over.<br /><br />I have a 900 CCA optima spiral cell AGM that will barly turn it over only once.<br /><br />Both these batteries should be powerful enough to turn the outboard, right? Is it just that they are deep cycle, or is the starter going bad?<br /><br />~gratis

500cca should be more than enough.<br />Don't know enough about those gell and spiral batteries to comment on them.<br /><br />But we used a 3 year old "regular" lead/acid deep cycle battery to fire up many engines, much larger than yours.<br /><br />I would try "normal" starting battery, maybe one from your car.<br />If that doesn't do it, then you have a problem.<br /><br />Start by cleaning and tightening all cable connections from battery, solenoid, starter.
