70hp force, siezed on king pin

[gwmichie]

any suggestions??
just picked up a little bayliner capri for a few hundred dollars. this boat was brought to the coast about one year ago and did not have a salt water anode. when I got the boat the motor would barely pivot by turning the steering wheel. I tried to spray the shaft with penetrating oil and work it loose. not much luck, you have to unhook steering and put a break over on it to move it now. is there anything I can try short of pulling the motor to fix this problem? any help/suggestions would be appreciated.

thanks,

I had the same problem in a much smaller motor. At least in your case you can still move it in my case it was totally seized! Anyways, the only proven method is to keep shooting light grease for now into the zerk fitting until you push all the old grease out while at the same time applying heat with a propane torch. Provide some shielding to components and flammable parts like fuel lines. Since heat goes up, start at the lower end of the kingpin going up. It's hard to do these two things at the same time, so alternate applying heat and shooting grease. When new grease starts to push out stop shooting grease instead continue with the heat while trying to move the unit back and forth until it is really loose. Cool it down and thereafter, shoot grease again this time with the proper grade until all the light grease is push out. Tip, you have a better chance of success by applying large amount of heat instead of slow heat. If you decide to go this way, you cannot stop or quit until it is fully loose. Stopping and going will just make things worse. You have to do it in one session with a generous amount of heat. DO NOT USE A HEAT GUN IT WILL NOT WORK.

Different engine (125) but, nothing (incl. grease and low heat) would free my king pin. Had to dissasemble it, carefull not to ruin the plastic/teflon sleeves, and emory cloth the rust and other stuff off the shaft. Then reassemble after slathering the shaft with antiseize. Moved so freely it chipped the newly painted pivot stop.
