Re: Mercury-Yamaha 90 FOURSTROKE: Testing Tachometer Signal

I wondered about that but it’s hard to say, because at the end of each day, I put the boat battery on a maintainer so it’s always charged at the beginning of a day anyway. I suppose I can watch the volt meter. If it gets up to the mid-upper 13V range while cruising at say 4000+rpm, can I assume it’s...

Re: c.1980 Mercury Stator Wires Are Like Rubber Noodles

The spark plug wires are not exhibiting signs of decay. Some of the other ignition system wires, specifically some of the motor ones associated with the stator and timer base/trigger can turn rubbery.
