Snapped Impeller Housing Screw

[Knot Waiting]

The self tapping screw that threads into the lower portion of my raw water impeller housing snapped during re-assembly. I cant find an identical screw anywhere without buying an entire impeller kit. Would it be acceptable to use a long stainless lag bolt and nylon lock nut as a replacement? The hole goes all the way through and overhangs the lower unit casting allowing plenty of room to accomplish this. Thak you.

I just drill em and tap em for a stainless bolt.

Thanks Jason (you've given me good advice in the past too) I didnt think it would be an issue but ya know, never hurts to ask.

just don't over torque it. That part of the pump cover and it isn't the strongest. Believe me you don't need to muscle it. Also, if this is a saltwater drive put some perfect seal on the threads before you put a bolt in.
