I have a 06 mercury 40 hp outboard that is a 4 stroke that has manual start . The boat used to have a older 60 hp mariner 2 stroke that had power trim and electric start. I got the 40 hp mercury outboard because I was thinking the 4 stroke would be a lot more efficient on gas then the 2 stroke. Anyways to my question , on the 40 hp 4 stroke mercury outboard I have I want to figure out how I can get the charging wires to charge my battery on the boat to run the electronics . It has manual start and it doesn’t have a rectifier. I did some reading about this and it says there should be 2 wires coming from the stator on the flywheel. Mine has 2 yellow wires that are capped off about 12” from the stator. Just wondering what to do with them wires or will these wires not work for me on a manual start? I know that I will need to buy rectifier to install on the engine and possible connect the 2 yellow to the rectifier and connect ground to engine and red will be power to battery and grey should be for the tachometer if I am correct?? Any help would be great guys I’m new to outboards . Thanks
