2009 Yamaha 4hp 4 stroke F4MLH
Can the 2009 4hp 4stroke be fitted to charge a battery?
The Yamaha website FAQ says this:
"I would like to use my manual-start small horsepower outboard motor to charge a battery. Can my Yamaha’s charging system be modified to be able to do that?
An optional Genuine Yamaha rectifier kit is available for many models. It includes a rectifier, fuse, and wire harness. Installation of this kit will allow an unregulated charge to the battery. Kits are available for the following manual-start engines: 2 Stroke: 8hp, 9.9hp, 15hp, and 25hp 4 Stroke: F8hp, F9.9hp, F15hp, F20hp and F25hp. The part number for this kit is 6G1-81970-00-00. Contact your local Yamaha dealer to purchase this kit."
So, according to Yamaha's website, only 8hp -25hp. Can the 6G1-81970-00-00 be used on the 4hp? Great if yes but if no, is there a kit for the 4hp and what is its part number?
