Gettin the Prop off....!

[Dmzhmdepo]

Hello helpfull commrads,<br /><br />I have a 1974 - 40hp merc. Am trying to remove the old worn-out prop, but am having trouble. Do not want to go banging on it. Is there a tool (puller?) out there to use? Current prop # is 48-73136a-4 13p. I have the nut off but nothing wants to budge. The answer is probabley very simple, but am a newbie and don't want to break anything. Thans for any help. dmz.

Re: Gettin the Prop off....!

DMZ, there are no simple answers to this, only ways to keeping it from happening,and that is anti-sieze on the splne when the prop was mounted. This should be done once a season,even if the prop is fine.<br />But now, you are stuck with a mess. I have,in extreme cases, had to cut them off the spline with a die grinder.<br />Your best hope is to get it off by frequent soakings and tappings with WD40 and light taps with a rubber mallet (to vibrate the shaft,and allow the 40 to run down it).<br />Then when you find the penetrant on the other side, get a good wheel puller that fits. And pray. An impact wrench on the wheel puller (if it is a good one) can help too. Heat works, but t also destrys the seals in the lower unit,and the rubber hub of the prop. If the prop has "become one" with the propshaft, it' a good bet that the lower unit has also suffered from lack of prevetive maintainence too, so it may need new seals anyhoo.

If it that bad I would use a die grinder<br />and cut it off.<br />cost a prop but does no harm to the engine.<br />Then clean with a good wire on the die grinder.<br />Rex A. Hubble<br />P.S. I'M ONLY TAKE ABOUT THE PROP<br />CUT DOWN ONE SIDE THEN 180 AND DEGREES OF THE<br />FIRST CUT.<br />AND WORK YOUR WAY DOWN TO THE SPLINE.

Been there done that. I put a 20 ton puller on a prop and cranked down on it until threads of puller started to get damaged, nothing. Lots of stuff flexed, but prop didnt budge. With thru the hub exhausts you can tilt up lower unit and fill w/water to keep seals cool when using heat to try to dislodge prop.
