Here's my tale of adventure getting a prop off. Also search in this and other forums for words like stuck and prop and you'll find a lot of stories and advice. Good luck!<br /> Stuck prop thread

Hey D. Why did you have to remove the thrust washer? Once you got the prop off, you were home free.<br /><br />On removing the thing. Don't want to use heat as it will/can mess up your seals in the lower unit. A real good penetrating oil over several days with pressure on the prop (wheel puller) should work. I use Kroil....stands for Kreeping (creeping) oil. Comes out of Tennessee and machinists in industry swear by it....that's how I got onto it. Is said to penetrate to within 1 millionth of an inch.<br /><br />Anyway with a puller permanently affixed to the prop and a daily dosing with Kroil the sucker should give up in a couple of days. <br /><br />A good blast with a hair dryer would help things along.<br /><br />And as stated, when going back on, GREASE THE DAMN SHAFT!<br /><br />Mark

Re: MERCURY PROP REMOVAL

Hey Mark - I don't know if I actually removed the thrust washer or not - I don't think so. Like you say, I think I just put the new prop on. It was a while ago and I can't really remember what I ended up doing. I've had the new prop on for a season A-OK. I do grease the shaft now and just remove it once a year just to keep it honest.<br /><br />One thing I probably posted in a different thread - for me, the prop (probably original) was less than pristine anyway, so it wasn't a tragedy to have to replace it. If I had it to do over again, I would have just carefully cut it off rather than mess with trying to pull it off at all. The replacement was only about $60 and is a better prop for my use anyway. I would recommend that unless the prop is perfect, with a small engine like this, with fairly cheap replacements, it is not worth putting a heck of a lot of time/effort into saving the old one if it doesn't come off fairly easily. Just a thought.
