Stripped lower unit oil level bolts

Matt as a couple have already mentioned and impact driver will take the screw right out. Harbor Freight has them for less than $10.

So, how do you propose to take the screw out with an impact wrench when the head is broken off??

Unless the head is broken completely off the pressure on the remaining stud from tapping on the impact driver will usually lossen the screw. Notice we are talking about and impact DRIVER not and impact Wrench. If you aren't familiar with impact drivers they generally have different size and type tips. When you put the tip on a broken stud and tap on the driver it makes a twisting motion which lossens the screw similiar to using a wrench on a square shank screwdriver. Like Dreamer said I've been using these since the 60's also and just used mine about three weeks ago to remove a 8mm stainless screw from my motorcycle that the head was completely gone on.

Thanks gentlemen.
My bolt head is not completely broken off, but stripped in terms of my existing (largest) screwdriver. Imagine a bolt that requires a nickel instead of a dime to fit in. Of course the edges are also a bit rounded from the material that broke off when I tried to remove them.

I'm splashing the boat Sunday to drive it to a boat yard. They will haul it out and set it on blocks to allow me to touch up the very bottom of my sponsons. Once there I will try again and check out these other tools/options suggested.

Thanks again.
