hi guys, im new to outboards but am willing to tear into them if there broke.
here's my story. while on vacation my evinrude 9.5 was running good ,started w/ one pull all the time. i bumped a rock at trolling speed ,stopped the engine and checked the prop. just had a small burr on it , so i did'nt think much of it and started the motor again.i noticed it took a little longer for water to flow out of the exhaust port.there was't as much volume either.i took the boat back to the cottage for the afternoon and left it untill evening and trolling time.when i tried to start it again i coughed af few times w/ each pull and finally started after many pulls.water was not flowing at all and steam began to come out of the port, so i immediatly turned it off.when i opened it up at home the impeller was in 8 piecesw/ only one paddle left intact.the previous owner installed a new impeller before i bought it in june. and i only put 2 tanks of gas through it while on vacation.
to make a long story longer, would hitting the rock cause damage to the impeller? was it a bum impeller? or is this a common issue w/ this motor?

You may hot as many rocks you want, almost, it will not affect the impeller.
Most likely 'someone' has started it for a few seconds without water (?), or the impeller was 'old' when installed.
Just be sure you find all remaining pieces before installing a new one. A wing stuck up in the water tube will not be good! |

Hitting that rock would not have damaged the impeller. Either it was not changed as the previous said or possible the wrong one installed. This is not common with new impeller installs. |

the seals were shot in the lower end, dont know it that would make a difference. oil was mixed w/ water when i drained it. |

wrong impeller, maybe, the guy i bought it from did'nt seem like any kind of a mechanic.
the pin on the drive shaft took a bit of metal off the housing when i removed it , should i replace housing? |

No effect either. You are looking at doing some maintenance on the motor. I have a 67 - 6hp and just went through it too. At least when you get it renewed - it should last you a long time. Seal kits aren't that expensive so - it is well you checked it!! |

It is a short pin? Did you forget to remove it before pulling the housing? I don't see how it could touch any housing otherwise? |

It just splined - and should pull free with little effort? don't get it? especially on a 66 model year? |

thats why it took metal from that cover , or housing, because the whole works came off the shaft. |

It should drop right out. I have seen instances where hitting a solid object like a rock, can cause enought force to do damage to the Spline area. I hope you didn't hurt the splines - engine crankshaft or driveshaft in-that they have twisted enough to lock together. I have a 10 hp that came close to doing that but luckily, it wasn't hard enough to ruin it. Solid objects in contact with the propeller will do damage. Keep us posted. You may have to pull the powerhead (not difficult) and see what is going on with the shaft. The shaft will then come out with the motor removal and it will be easier to work with. |
