1975 85hp sticky grease looking stuff coming from the stator

I have some greasy looking substance (but hard and sticky not like grease just same color as grease)coming out from under the flywheel. I was having problems with no spark, but I replaced the power pak and it started running again. I was told by someone that this greasy looking stuff is the stator melting and going bad and that is why my power pak went bad. Is this the case, and if so how hard is it to replace the stator.

They told ya right. The black caca running out is from the coils in the stator. I don't know if that caused your powerpack to go south or not but you're due a new stator.<br /><br />g'luck & c/6<br /><br />Hooty

Thanks Hooty, I also ran a search on this site and found lots of good info about the goo, but did not see anything that said if it would make your power pak go bad or not (just that the stator would not send any voltage to the pak). Does anyone know? Also it seems that this is fairly common, do you always replace it as soon as you see the goo or do you test it frequently to see when it starts failing. How difficult would it be to replace the stator by a fairly novice shadetree mechanic.

Here's what Mr. Joe Reeves haz to say.<br /><br />Posted by Joe Reeves (Member # 6826) on October 12, 2002, 11:24 AM: <br /> <br />Rock..... With no intentions of stepping on anyones toes, I strongly recommend that you replace that melting stator. I assume that it is the 35amp type which has a tendency of running extremely hot, and unfortunately a repeat (in time) of the melt down will take place due to the extreme heat generated.<br /><br />The stator serves two functions... one of which is of course to provide AC voltage to the rectifier which converts the AC to DC in order to charge the battery.<br /><br />The other function being (two of the large black coils) to supply 300v AC to the powerpack(s).<br /><br />The melt down always affects the large black coils. This results in a voltage drop to the powerpack(s) which in turn results in faulty, erratic or non existent ignition. Erratic ignition will result in piston and cylinder wall damage.<br /><br />Be sure to torque that flywheel nut properly, 35amp=145 foot pounds, lesser amp=105 foot pounds. Good luck....... <br /><br />The biggest problem you'll have, and it ain't all that bad if you've got the right tools, is pulling the flywheel. Do a search, there's plenty of discussion about pulling flywheels. I'd get a manual first though.<br /><br />c/6<br /><br />Hooty

Thanks again Hooty. I will replace the Stator and hopefully get back to fishing soon.
