outboard stripped spark plug thread

[Randylandy]

Just bought a new(old) boat with a old v4 Johnson 60hp on the back. pulled one of the plugs out and found the plug has been cross threaded or over tightened and has striped the thread. Is there any way to fix this or is it time for a new head? Also if anyone has one of these motors could you please post a pick of the throttle linkage set up under the cowl as mine is missing. Model number is VX13A and guessing it is of a 1970's vintage.

Cheers

helicoil?

Your local tame head reconditioning service can probably helicoil it with the engine in situ without even dismantling...............

... take it in on the trailer...

helicoil?

X2. No need for a new or reco head. Helicoil will make it as good as a new one.

Helicoil it, ITs a DIY process if you want to buy the gear and shouldnt cost you more than about $70 if its easy to get at to have a mechanic do it.

There are also special helicoil like repair kits for spark plug threads, I think they are a little cheaper than the standard Helicoil Kits.

I have the V4 135hp / 1975 vintage ... plus have a FULL repair manual on most of these motors ....

If you could post up a pic of the motor with the area of missing linkage ... I can send you an appropriate picture in response

so if you do the head in situ, how do you trap any swarf?

[Gavo]

Go ask your local mower bloke probably cheaper than a boat repairers. They do them all the time on briggs engines. Blow out the cylinder hole with air and anything left would blow out when you start it

[Blknight.aus]

lots of grease on the tap and I set it up so that its on intake stroke with the valve open for the pot Im working on with a blower running into the air intake.
