I have an '05 Johnson 15hp 4 stroke without electric start. Can I charge my battery with my motor?

For yours (assuming i have the model number right) it should be the part on this link.

Hope this helps and good luck!

FuzzyGrub mentioned about charge rate and I can second it. It was fine enough to keep a battery topped off as long as I only used nav lights (night fishing) and the locator.
IMO, for the cost to convert your engine to charge a battery with the little output it will give, save your money. Go buy a small solar panel from Harbor Freight or someplace like that and you will be money ahead and get the same results.
Your stator/magneto produces alternating current (A/C) and your battery produces and needs direct current (D/C) for recharge. A rectifier is the electronic device that converts the A/C output of the motor to D/C so the battery can be recharged by it. If you're trolling with your outboard, that may supply enough voltage/amps to operate the nav lights and FF during trolling, so that there wouldn't be any drain on the battery as long as the motor was running.UtahBassKicker said:Thanks for the link, I'm still not sure what to even look at though. I saw that a rectifier, whatever that is, is $145. My guess is that it's probably not worth it at this point. Thanks again.
