voltage regulator or stator

[walleye1968]

2001 40 hps/n ot199135 i had removed the starter
and behind iti saw 2 yellow wires runing frome the stator to the
voltage regulator the bullet connectors wher melted
the stator test ok i have no spec to test voltage regulator
any ideas

thanks

Re: voltage regulator or stator

The bullet connectors are a weak spot. I'd cut em out and wire nut it for now.

If you don't have a voltmeter in the boat, hook one up to the battery. Start the engine and see if the voltage rises with RPM. If it does, replace the wirenuts with solder and shrink wrap. If it doesn't replace the voltage regulator and either install new bullet connectors on the wires or solder the new regulator in.

hope it helps
John

Re: voltage regulator or stator

so i cut out the bad connetors put new in whent to the lake wit6h volt meter
at 800rpm i had13.25v and at 4000rpm 14.25v
i dont no if the bgad wiers had any thin to do with this but this motor
has not run this good all year or was it to do with my prop
i was runing a10.3/8x13p wot 4800rpm at 24mpa
put on a 10.5x13p wot hit 5200rpm at 26.5mpa
did fixing the wiers help with the rpm gain or did an 1/8in more in prop size

Yer good to go on the electrical. Usually the hot wires eventually take out the regulator. You dodged a bullet.

The original prop was steeper than the new one. Pitch is approximate as the pitch is different at different points in most modern props. The pitch is "progressive", a politically incorrect term as far as I'm concerned, but descriptive.

Most merc outboards would rather run near the top of the WOT RPM specification than the bottom. Don't know what that is on your motor, but I suspect ya made an improvement in that department.

hope it helps
