Hi. simple question on bow and stern rails--- what were used #10 or #8 sheet metal screws to hold on the rails, and where they ovals slot or phillips.

---

The screws are #10 x1" oval head slotted. Boston Whaler didn't start using phillips head until the 80's. I have a 1979 Montauk, and all screws were slotted. But I would use phillips for your work.

I agree with Larry.

My 1985 Outrage seemed to have come with both slotted and phillips.
I slowly replaced all the slotted that I came across.
Now all mine are phillips oval head. (some exception with phillips flat head where needed)

---

I concur. Phillips is the better drive.

---

I just broke off one of those screws, it broke right below the screw head. Is there any way to get it out of the hull so I can put in a new one?

Thanks-
Scott

Was it the base of the bow stanchion?

---

If you can center punch it, (may have to file it first), you can use a reverse twist drill bit.

It's not going to be easy to center punch it though. Might be easier to grind or file a cross hatch.

---

Its the rear-most rail support. The screw goes straight down into the hull.

Maybe some kind of Dremel bit would get it?

---

I always overthink things, file/grind a slot and use a flat screwdriver. When you get the srewdriver in the slot give it a good tap to help free up the screw.

Sure, a small cutting wheel on a Dremel, or in a drill, will work.

---

You can also use a micro-hole saw.

Thanks for the ideas. Sounds like a challenging project. Maybe I will put it off for a while. I need to do something about these through-hull drains first, I suppose.
