If no metal shavings I wouldn't worry about it. Milky looking oil means water is in the oil. I would replace lower unit oil and run it a few times in the water then check again. changing lower unit prop seal is a piece of cake. |

If it was recently run, it looks like that. |

On those older lower units, if it's getting water in it, it will eventually push out the top. If it's not doing that, I wouldn't worry too much about it. Again, I'll ask, had it been run recently? |

I never really messed with trying to figure out the charging systems on those old motors, and completely removed them from all the ones we've had. I'd say if it doesn't show somewhere north of 13 volts when at half throttle +, it ain't charging. Russ has done a lot more tinkering with the charging systems on these things. |

The oil....next time drain it into a very clean pan. Check with a magnet to see if it has shavings. Pour the oil into a clear container and let it sit in your garage for a few days to see if any water phases out. The battery...check the battery voltage across the posts with the engine off. Start the engine, check the voltage again across the posts. If the voltage is the same running and not running the engine is not charging. Check on the posts not the cables in case there is a bad connection, then check the cable connections. Try replacing the voltage regulator first. Relatively cheap and easy. If not, it's the rotor/stator. |

There is always the Radio Shack $2.99 Fullwave Bridge rectifier(25amp). Or https://www.amazon.com/NTE-Electronics- ... +rectifier to test your a/c coil output. (30-40+ A/C volts out) Been using 1 on a 15 hp Yamaha 2 stroke for about 4 years charges at 14.8 vdc. |
