Stripped out drain plug


Recommended Posts

I stripped the head out of a hex drain plug when attempting to change lower unit oil on an evenrude 15.  Luckily I just walked away from it rather than getting too pissed and screwing it up more.   Any ideas on the best way to get the plug out?    I’ve looked on the inter webs and easy outs as well as cutting a slot for a flathead screw driver are ideas.

First aquire a replacement screw/plug and washer.  Then get an assortment of Torx bits, choose the one that won't quite fit into the hole....and just smack it in with a hammer.    Remove the stuck one with a 1/4" socket....and throw it and the Torx bit away.

Are the replacements standard size or will this be a pain finding one that fits a 1979.   I have another lower unit so I could take from it but not so sure they aren’t in worse shape

Easy out's work, but you will need to drill it out quite a bit, and if you break it off in there, you're really in a pickle. 

Do what Wrench says, get a cheap set of Torx sockets, (Oreilly has a set for ~$15 that goes to T55), hammer one in and try that. 

I have never had any luck cutting slots in anything other than small machine screws. 

I'm sure you'll need to order the new plug from OMC, drain plugs are usually very short and have a larger head to seal against the washer, not something you'll find at the hardware store.

Yes the threads, thread depth, and head are the same across the years.  Some have magnets, but yours doesn't...I don't think.  Just break the magnet off if the replacement has one.   

If you can't find one just let me know and I'll drop one in the mail for ya.

How'd the lube look?

Nice and dark black.   What’s interesting is, it was missing the back thrust washer.   I had milky oil leaking out, which lead me to drain it in the first place.   The oil that came out of the lower unit drain was black to my surprise.    I’m wondering if a seal replacement is in store, or if I could take the thrust washer off the other lower unit and it would seal as I had about an inch of play in the prop on the shaft.    It’s been a project and I enjoy it.     
 

on a side note I acquired a 1947 Firestone 3.6 hp that I restored spark to last night.  If I get it going I may try to do a full restore with paint and the whole works

Milky discharge coming from the prop area is usually from raw fuel/oil in the exhaust housing.   Look for a pin hole in the fuel pump diaphragm, a carb float level that is set too high, or an ignition issue that is causing inconsistent firing, or firing out of time.
