1986 25 hp evinrude, bolt on left top side of starter is stripped out. Tried blue loctite and did't hold, tried super glue and didn't hold. If I hold/put pressure on starter it will engage flywheel and works just fine. When I get back to Florida my go to great friend Bill will know what to do. Any suggestions for now would be appreciated. Don't want to use red loctite incase I ever have to take it out. Thanks
Drill it out and helicoil/timesert. May also be able to drill it oversize and tap it the next size bigger.
I recommend drilling and retapping if there is adequate room.
theysaid Till you can get it fixed right, might try some Teflon tape applied generously.
Drill it out using a left hand drill bit. 9 times out of 10 the broken bolt will come out before you are done drilling.
An old farmers trick is to a piece of copper wire in the stripped out hole. The wire forms to what is left of the threads in the hole. Works best with a bolt that has good threads. I have made threaded inserts on a lathe to put into the hole after it was drilled out and tapped to a larger sizr. Take a bolt a that is larger. Drill through the center, thread to the size of the starter bolt, drill out stripped hole and tap to the size of the bolt. A little loctite and you are good to go.
THAT is the correct fix. There are lots of quick fixes, but THAT fix is best by far.Quote:

If the hole where the bolt goes into goes all the way through you could just use a size smaller bold but longer and put a nut on other side. That would make you a good temp repair where you could use until you get home and can make proper repair.
iI agreewith tiefire

The OP's issue is a stripped thread, but good adviceQuote:

looking at it at the garage looks like there is plenty of room to put in smaller bolt reverse direction with washer/nut on it and that should work til *I get home and then fix it right. Wife has been trying to convince me to trade jon boat and 2 motors in and buy a new motor.
I would be all over it if she was going to let me trade into a new oneQuote:

Nope, threads in the bolt hole stripped. Go to the hardware store and get the next size up in a self-tapping bolt. You'll change the size of the threads from NC, NF or MM to whatever is next.
Looking back I see you did a temp repair. Hope you used a locknut.
Good ole Bill got it done, RIGHT, and works really good. He also replaced some bad spots in floor and repainted everything that needed it. Best friend/fishing partner I could have. Very lucky. Should last a few more years so at my age I think I will keep using this motor but keep my eyes open for a REALLY good deal. Used motors are very very expensive right now and hard to find. Thanks for all the advice/comments.
Great to have such friends
Glad you got it fixed right.
I prefer to do it right, as if I was the next man to be going back in there.
Usually, It is!
