Don't want Joe to buy one of these for his GT40 though 'cause it'll turn the engine over backwards. Remember ARCO 70200 or something that cross references to it for the small high torque starter that rotates the right way. |

Take it apart clean it up and put it back together -- if you find big chunks of magnets or something melted then move on and get a replacement. I don't know if I am too cheap to buy a replacement or just too lazy to order one - but its been a long time since I couldn't get one back in the game with a bit of emery paper, contact cleaner, and compressed air. I have taken to holding the brushes in place with little zip ties until I get them partially inserted and then removing the zip ties... I suspect somewhere there is a slicker tool for that but I have been too lazy to order one.

Joe, I'm sure glad someone else thinks the same as I do with starters. I've been chastised too many times here even suggesting opening up a starter!! BTW, I'm sure you know that new brushes are available and not expensive but typically not needed due to the low run hours on a starter. |

Yeah I got that, though I'm a bit slow with some of this stuff since direct drives are all new to me - thanks for clarifying though... Funny, I was reading another post a couple days ago where you were discussing rotation of an older (1980?) SN and had said CCW. I had to stop for a minute and go check mine because I had already taken delivery of a used 422 RH from a buddy of mine - thought that might be a bit embarrassing if I had to see if he would take it back because it was the wrong hand |

This whole rotation thing can be kinda confusing.
You have a standard rotation engine so it needs a clockwise rotating starter if you decide to get one, which the Arco 70200 is. Then you have a 1.23 to 1 pcm transmission which reverses the direction of rotation inside the transmission. That means your LH (normal rotation) engine is spinning a RH (reverse rotation) prop And that means your Acme 422 RH prop is correct for your boat and will make your boat go forward when you want it to I think you understand that already, just thought I'd say it again |

Well I finally got around to installing a new Arco starter using Gary's link to Discount Marine. Works perfect, cranks strong and much faster than before. Guess the old starter was just ... old. And weak.
Thanks to all for your input !! |

I figured you'd get there eventually. Maybe you can send your old starter to Pete for a fluff and buff I wouldn't get rid of it, keep it around as a spare that you know will at least work or tear into it and do your own fluff and buff |
