Re: 2000 Yamaha 9 HP 4 stroke pull cord to charge battery?
Further to my previous comments, if keeping the battery charged is our only concern, I'd recommend the use of a small solar panel. I have been using two of them for a couple of years now and they work very well. There's an oufit called ITC (I think) that sells various small to medium sized solar panels. I use their 5 watt unit trickle chargers. You must realize that these panels will maintain a charge although, they will not charge a battery from a dead condition. I run a Humminbird XT400 fishfinder with a lawn tractor battery. I keep it charged by connecting the solar panel to it in the evening when I come back from fishing and let it charge the next day. Don't even have to take it out of the boat. Depending on the security of where you keep your boat, you can put the panel on/in the boat or, place the panel on a post at shore facing the sun. I also use the same set up for winter. I have three large deep cycle batteries that I leave at our cottage hooked up to the solar panels all winter. Six month later they're all charged up and ready to go. It really works great. Also, its easier to carry the solar panel to the battery rather than the other way around. If you do most of your boating activity during daylight hours, keeping the panel in the boat hooked up tho the battery will provide some charging providing the devices you are powering don't exceed the power supplied from the solar panel. I paid $80.00 Canadian for the panels at our Canadian Tire Store. It's likely a better deal than the rectifier.
