Hi All, I'm new to the forum. I have tried to search for the answer but no luck so I apologize if this is redundant. The boat I bought has an '89(so I was told) Evinrude 90HP VRO, E90TLCEM, with the VRO disabled - oil line plugged - burning premixed fuel. The tach is not working and the battery is not charging. Voltage at battery reads about 12V running or not. I see a few wiring splices and suspect some circuit bypass and/or alteration. The wiring is some what corroded - the T/T will not lift the motor as a couple of wires have broken. The threads I've read cover one problem or the other, but not both. The type of charger is also in doubt. Any and all help to fix these problemswill be greatly appreciated.
