pardon the dumb question, do outboard motors charge the batteries while running? I have a 1986 3-cyl Yamaha 40 HP. BTW, i have 2 batteries with the 1-2-all-off switch.
any recommenations please on a repair/service manual for a 1986 Yamaha 40HP - 3cyl motor (Model 40ETLJ).<br /><br />also, i am a new boat owner, and looking for advise if i should invest on a professional tune up for this motor. I have been using it for a month now and it runs well and it starts...
