Hi,

Looking at used 4-stroke 9.9's and wondering if the "electric" option
is worthwhile. I'd love to recharge my trolling-motor battery with the
outboard, but I'm wondering just how much current these small ones put
out? 20A? Anybody know?

I think my yamaha T-8 has a 10a circuit. I know it is enough to charge up a
low starting battery after a couple of hours running to fire up the big
motor.

My 50 Hp Mercury four strokes are only rated at 18 amps output, so I doubt
the 9.9 would be any more than that! Any specific brand you are interested
in?

The website for Mercury doesn't list the alternator output for the 9.9, but
they list the 15hp as having 6 amps for a manual start or 10 amps for
electric start.


I wouldn't count on getting any useful charge out of your outboard, at least
with respect to your trolling motor. It will run the electronics you might
have and recharge its own starting battery but that's about it.

Thanks! I'll put electric start/charging as "not worth it". As for brand: it
will be used, so I'm kinda tied to whatever's available, but I'm favouring Merc
and Yamaha. (My impression is that older Hondas were heavier)
