SUZUKI 9.9 HP LOWER UNIT

[jsty40]

Trying to change impeller on 9.9 Suzuki, 1989.<br /><br />Never attempted before on my own. Followed instructions to disconnect shift rod, removed 4 bolts and unit will not drop.<br /><br />Seems locked somewhere else. Store I purchased impeller and instructions say no, that was all that was necessary. <br /><br />Any suggestions ? Store said possibly that drive shaft was rusted into power head somehow ?????<br /><br />Maybe need a BFH ?<br /><br />Thanks,

well if it has not seen routine scheduled maint it may be the shft splines are frozen together. try using a dead blow hammer and striking it just afft of the midsection. dont hit the ventalation plate or you will be posting about welding it.

thanks for the advice rodbolt, but I read this post too late. Cracked 1/2 of cavitation plate off in the process.<br /><br />Any idea if I spray penetrating oil on the main shaft just underneath of the flywheel, will that possibly make it down to where my problem is ?<br /><br />Not sure where you mean just aft of the midsection. What is a dead blow hammer ?<br /><br />Thanks for the suggestions.

Finally did get the F*#@%er off. Used lots of penetrating oil, brute force and some big screwdrivers, hammers, and crowbars.<br /><br />Motor is back in good working condition with a bit of a gap on the lower unit seam. <br /><br />Heard that the seam doesn't necessarily have to be water tight. Seems I have some exaust coming out of there instead of the prop.<br /><br />But for those who have stuck drive shafts,,,advice is to keep at it. Turn it upside down, spray lots of penetrating oil in there and keep working at it.
