Drilling holes in transom
In a couple of weeks I'll be installing ext steering.
What is the best method to make sure I don't have any leaks?
I saw a post where the op was wanting to coat the exposed wood with some type of wood sealer in case the 4200 failed to seal.
Is this a good idea? Could it prevent the 4200 from sticking?
I'll be using 4200 under the bolt heads for sure, but not sure if it should be used inside the newly formed bolt holes.
If I drill the holes so the bolts will be a snug fit, It will scrape off any sealant I apply.
If I drill the holes for a loose fit, I can get a good seal around the bolt, but I risk the plate moving.
What abt using a countersink bit and just touching the bolt hole opening? That should make a small void where sealant would be trapped.
Should I just seal the whole plate?
I'm a bit OCD when it comes to drilling below the water line

Like Black Baja said. Make sure you seal the holes properly. I have seen a transom completely destroyed and rotted by not sealing the bolts on an add on hydraulic steering system. The destruction took less than 5 years

That's how I got my k-plane off, worked well. Like you said wasn't fast, lots of plastic pry tools, numerous applications but didn't damage the gelcoat at all. I used 5200 to reinstall it too because the transom where the huge hole was cut looked like it did the day it was installed in the factory.

absolutely, i would rather use a little effort to remove a fitting than worry about a potential rooted transom. after all, if its below the waterline i would not want somthing to come off effortlessly. most threw hull and transom fittings recommend 5200 such as why most boats transom assemblies etc come sealed with 5200 from the factory. it is also removable as mentioned above, may take a little effort but it can absolutely be removed.
