How do I dissolve corrosion between the upper and lower unit on an outboard engine?
How do I dissolve corrosion between upper and lower outboard unit so
to get at the impeller? I took all five nuts off (125 mercury sal****er) the studs holding the lower unit on. I had to use penetrating spray to get the washers off. After whacking the seam dividing the upper and lower with a rubber hammer till blue in the face I etched/scored/scratched the seam to allow penetration spray to work in, nothing. After 24 hours of repeated spraying whacking and more scoring, the two halves still won't come apart. Short of pounding in a chisel (gouging aluminum), and prying them apart, anyone have an idea? |

Try heating just one of the parts, a gas welding torch gives a lot of heat in a small area. In Des Moines, one supermarket chain has dry ice in a vending machine for two bucks a pound. Chill and then heat one half. Casady- Hide quoted text - - Show quoted text - Heating is going to ruin the paint. I have used the putty knife followed with a chisel successfully on i/ o's. Really gop up the steel parts with antisieze when you put it back together. |

May have to cut a hole in the leg and then cut the shaft. replace shaft and have leg welded. Also, I had to have the chips in the leg welded on a Mariner 15 that did not want to come apart and had to pry apart. |

But that's on i/o's. Maybe it's different on outboards. |

You do know that once you remove the bolt that holds the trim tab on that there is another fastener underneath it that holds the lower unit on. |

Try a boating discussion board. Rec.Boats is a vehicle for right-wing trash to whine about President Obama and for those few of us centrists or slightly left of center here to laugh at the righties. You're becoming an island onto your self. Even the RATS are abandoning Oboobuh's dingy CB .... "The debt ceiling should not be something that is used as a gun against the heads of the American people to extract tax breaks for corporate jet owners or oil and gas companies that are making billions of dollars," Obama said during a town hall that featured questions posed through the online social network Twitter. .... http://finance.yahoo.com/news/GOP-sh...47664.html?x=0 What class Here's a cartoon of the Classless One http://global.nationalreview.com/ima...oll_101129.jpg |
