Re: Soliciting thoughts on a new outboard
You sure don't need an independent starting battery for this outboard.
The boat that I've sailed for the last 3 seasons had a 9.9HP 25" shaft Johnson with electric start and alternator. If an engine is in good tune, it will start with 5-10 seconds of cranking and not make a dent in your battery power.
If I were repowering my old boat (instead of working on the A4 in my new boat), that Yamaha would be my first choice, hands down!
