- In this episode I have discovered a stripped spark plug hole and I will take you step by step on how to fix the threads with a steel insert and make it like new or maybe even a little better.

Im here because i got a '77 35hp Johnson the other week and when i pulled the plugs out the helicoil came out too. Thanks for sharing as i was looking for a better kit
Should work for you, thanks for watching
I have done several of these rethreadings and found that it really pays off to work on a pulled-off head. It s as simple as taking out 6 bolts and will eliminate the risk of great damage resulting from a leftover chard in the cylinder or of hitting the piston with the tool. It also smplifies clean-up. In a nutshell, t makes the job easier and faster. Regards !
I’ve used helicoils in the past. Great invention. Got an Evinrude 15 like yours, little newer maybe.Those are really kick butt little motors. It will plane a 14’er with 2 fisherman, and only weighs 75#. Perfect.
Man this video was very helpful. NEVER KNEW these parts were available. I fix my own cars and anything I get my hands on and I have never seen this kit in the parts store or heard anyone recommend getting it as a solution for that particular problem where I live.
Either the parts stores are too stupid to know about it or they just prefer that people go buy a whole new head or engine.
The corruption is deep. Again thank you for the tip. This is the better replacement part for the job. Do good work and achieve God results.
Appreciate the kind words. Glad this was helpful.
I thought Helicoil was all there was! This is good to know. Ford F150 blew out a sparkplug on my Father's truck. We used Helicoil. Wish we had known about this...
super job saving them plug thread love your work thank you
Much appreciated, thanks for watching
good fix i used the same kit on my friends 15 hp. thanks for sharing this fix.
Right on
Very good Michael. Keep them coming mate!
Thanks, will do!
Good Video just did this on an 86 60hp Johnson quality result!
Compression check a success on my 85 Johnson 15hp ,cold engine 85 and 80 warm motor both cylinders 110 # lbs 👏🤙
Great job, you made it look dead easy
Learning more from you thanks Chris 😊
Glad to hear it!
Fantastic video!
I admire your handiwork style.
I too work on outboards and build boats as a hobby.
Very well done indeed.
Only comment is I would have done the carb rebuild right away, why not fire air fuel!
Need them all. Sea foam is a bandaid not a fix in my opinion.
Great job however!
Noted, thanks for watching and commenting
Thank you brother! Quite informative!
So it seems like a real step up from helicoil.
I learned something 👋
That was very cool
Sweet repair kit
I have a 90hp mercury on my 2019 suntracker. I had purchased it from the marina rental company. It ran flawless last summer, took it in for some basic winter/seasonal maintenance and the tech called us and informed me whomever performed service on the motor sort of stripped a plug but the new plug went in tightly, but its still running strong. This isnt something I would try to accomplish on my own what do you think a boat motor service center would charge for this type of service? The service folks I took it to saidthey dont do helicoils.
nice clean job 👌
Thank you! Cheers!
Used those in structural steel in buildings work great
Michael. Have you ever done a engine swap from a steering to a tiller video I watch This Old Outboard and he did it w/o disassembling it. He does really show close ups like you do. So if you have a video please reference it. Thanks Rick
I have not done that yet. I have a candidate that I may be able in the near future. Thanks for watching
This happened to me today i put J8C spark plugs in my outboard 1969 Johnson 25 i probably should have just put the J6C that i pulled out i think.
I have a Johnson 20 hp anniversary model 1972,I think?will this kit fit my head? I have a stripped plug?
depending on the length of thread, it should, thanks for watching
How did the stainless prop perform on the small johnson?
not any different than an aluminum one.
Can this be done without the Locktite?
Still would like to see the banana boat in the water!
Me too, working with the DNR to get it registered. As soon as I get it registered it will be on the water
Question unrelated to subject, when adding new high and speed needle packing how tight should you go with the 7/16" insert?
just enough to create some drag
What size is the tap? I have a 77 70hp evinrude that has a stripped plug?
Make sure you buy the thread repair kit that matches your spark plug size, thanks for watching
Brother I have a question and could use your help I have a 1998 johnson 15hp that keeps blowing the coil pack I put in a brand new cdi and coil pack and it had spark at both ran the motor for just 2 minutes and it shut off I checked spark again and I'm only getting spark to the bottom plug it keeps blowing the top portion of the coil pack leaving the upper cylinder with no spark I've cleaned all the grounds I'm lost please help
That's a strange one for sure, what shape is the plug wire in? that would be my first check, swap wires and see if the problem moves.
make sure the plug wires are not grounding out on the motor covers metal locking handle on the inside.
What about the metal shavings
grease on the tap catches most of them, air blast the rest, thanks for watching
@@Michaelsbackyardmarinawould have been better idea to use a chop stick with a little grease on the end, to pick up those shavings on top of the piston. Then follow up with compressed air.
Should’ve started engine
It ran and I sold it, thanks for watching
