have you cleaned the carbs and load tested the battery? -
Scott,
That battery voltage should be reading around 13 volts at idle and increasing up to 14.6 above 3000 rpm. This assumes your battery is in good condition and the rectifier/regulator is good.
If that battery is at least 3 years old, get a new one and start from there. Check the voltage, per the above - your r/r may be bad, and with only 10 volts instead of 12+, that could be your problem with the motor missing.
Good luck [img]smile.gif[/img] ,

the r/r tested bad,I replced it
but the new one tests bad alsso, no change in perf. I think something could have burned the new r/r out.Scott Lewis,Gary Yamamoto Custom baits, StayNCharge systems, Bassmedics, SavephaceComment

Scott,
That rectifier/regulator assy should be fuse protected from an overload. Check the fuses under the hood of that motor to see if they agree with what is in the Yamaha shop manual. I would guess there are at least two in the range of 20-30 amp.
Also, trace the wiring on the load side of the r/r
to the fuse(s) - could be a wire with broken/worn insulation giving you a short to the engine block.
