Changeing the bolt holes from 3/8" to 1/2" in a wo

[FP1201]

Here's the deal: the boat I'm buying has a LXL prop that uses 1/2" bolts, I have a couple LML props that are the same bolt and hub patten but uses 3/8" bolts.
Personally I don't see any issue with passing a 1/2" drill bit thru the hub, but the torque is much diffrent.

Drill it.

I have drilled out many props from 7/16 to 1/2 inch. I have never had a problem with it, even made a plate for a template so things were a little easier. Having a car motor that swings a 66 inch prop lead me to this as it is hard to find'em that size in 1/2" unless you order them.

I would drill it out . I personally would use a drill press to make sure the bore stays straight

I was thinking of using a brace & bit with the prop laying across my lap. :tard: Last time I used one in my lap it went thru and kept on going. :shock:

ok that sounds like a personal problem hat we just don't need to know about :lol: :lol:


I didn't mean to seem like a smart ass about (sorry if I did) it just meant to make the point that free handing a drill bit you could run off and even a small drill press would keep your bore straight

Brownells Gunsmithing supply has a poster that shows a guy with a hand drill whos obviously been drilling into the reciever of a rifle to the dismay of the onlooking owner. the caption is "Don't worry about them extra holes, the bases cover 'em up!"
