stripped SX-A (3L VP) dipstick threads

[boatdude100]

I read a Threadsert may be the way to go?
Can anyone confirm the thread gage for SX-A outdrive thread and/or dipstick thread?
Can I take the top off carefully, insert threadsert and just re-use the shims/gasket if ok?
Can the dipstick be reused with threadsert as this will widen top hole?

Cecil Marine seems to have the best price but for us it is almost $600 CDN. Can this part be had anywhere else at a better price perhaps? ("upper drive top cover and service kit")

Any other thoughts on fixing this brutally common issue?
Many thanks!

Ayuh,....... Every drain/ fill plug I've ever seen is 3/8"- 16,......

Thank you, is the helicoil route generally the way people go or do the wise cough up the $ and replace the cap?

Still looking for helicoil size for the
Top of outdrive dipstick tap. Its not the drain/fill plug at the bottom.
Thank you
