Some outboards are AC voltage for lighting only, not charging. You should check this. Yamaha requires optional diode for charging. You don't need to ramp down a 6A alternator, but it will naturally fold back. I don't think that you need a solar regulator at all either, for one panel. The panel will put out ~4A, for about 6 hours a day unless you manually follow the sun with it. That, basically, is float current. Everything should be about right if your use estimate is correct (and the sun shines).

Subject: lv-ab: charging from outboard alternator
I just bought a new 03 suzuki 4 stroke (9.9) for my sloop.
she runs nice!~
I called suzuki to get info on the alternator but could get absolutely nothing out
of them. All I can get is that it is a 6 amp output.
I just bought 2 new T105's and want to treat them right. Any experience out there
on charging from an outboard? Any concerns or gotchas? Are these smart alternators
that will ramp down to a float?
I'm installing an 85 watt Kyocera with a 10 amp regulator- so the solar panel and the outboard are going to be
it. I cool with ice so my demands are quite low. approx 20 AH's a day. I have about 100 AH useable from a total
of 220 (two gold carts).
thanks all.
