    Outboards do have an alternator that will charge your starting battery.  If you have more than one battery (like for a trolling motor or back-up battery), you may have a battery switch that controls the operation of the batteries.

    @jerry226.  All outboards have a stator or alternator to maintain charge for your battery as cjjjdeck mentioned.  In the case of your engine, I believe its a 20 Amp alternator that should more than adequately maintain your battery for you.  As cjjjdeck mentioned, if you add multiple batteries you can look at a battery switch or a digital charger which will maintain your starting battery at full, and switch to alternate battery to charge only when the primary is fully charged.

    Thank you two for your  responses. I have a switch and cables that I believe is for a trolling motor. I am thinking about getting a second battery for (just in case). this boat is to heavy to paddle if batt. goes dead.

    I recently bought a 2000 Fundeck 196R and it has two deep cycle batteries.  I found out that deep cycle batteries could cause problems so I'm changing them to starting batteries.  The issue I'm trying to solve is the transfer switch for this boat...if it has one...where would it be?  It's not on the helm panel.

    I'm also trying to locate a wiring diagram if anyone can help.

    One batt. is for starting the other is for trolling motor up front. I want to put two starting batteries so I can have a back up batt. I have a switch in back by the batteries and could switch if one went dead. we have a 45 gal tank and go for long trips and it would be had to get someone to tow you 50+ miles.

    I see there are a second set of wires for another battery. I don't see a switch. I have a 226 sun deck with 115 Yamaha.

    Just taking a guess here, but could the cable you are seeing be part of the wiring harness for the trolling motor?  I believe the wiring harness is a standard feature.  I know the battery switch is an optional feature.

    I have the wiring harness cables on my boat (although no trolling motor) and my battery switch was installed by a previous owner.
