A question that I can't seem to answer searching the forum , here goes:

Does even the most basic tiller with manual start have the ability through an alternator to keep a large optima battery charged in order to run depthfinder and a small stereo (2-6.5 midranges), running lights and possibly a LED light bar?

I dont have any experience with 4 strokes and the engine range i am looking at (15-25 hp) are much slimmer on features than mid range motors.

Appreciate any help on this.

I think most of the small outboards run stators not alternators, but the charging kits usually only come if they have electric start

It has it already. All modern electric starts do to my knowledge. My yamaha has a 10amp at WOT. Look at the specs on the zuki site, it will tell you.

The answer to your question is, maybe. Amp output varies from outboard to outboard.

If we look at the Yamaha F25, it has an output of 13 amp with a rectifier regulator. If you step down the the F20 it lists alternator output at 10 amp but there is an ** next to that number, so it will depend on which variation of the outboard you're looking to buy.

A light bar, a radio, and sonar shouldn't be all that taxing on a high amp/hr battery.

Thanks! Picking up the new f25 today!
