The NJBA and SCSC require Black Oxide bolts in the loader.
I've been using 5/16" stainless steel bolts and locking nuts. I've had one sheer off after only two rides with the boat (yes that means the head of it went through the pump). Fortunately, no damage to the leading edge. What bolt can I use that is robust enough to not break/rust/deform/etc?
Thanks!

Suggest ARP?
use black oxide bolts fine thread with normal lock washers and nuts so you can inspect for stretch each trip out. Adam

Are you breaking them on Delta/Sac River runs ???
its not fine thread. :220v:
use 5/16-18 x 1/12" black oxide bolts with nylocks and AN washers on the top side. double check you have clearance for the oil pan.
You got lucky it didnt get the impeller.
Don't forget to put a bunch of antiseize or grease on the bolts. They are somewhat of a bitch to get out when they stick.
antisleeze on the threads and on the angled part of the head of the machine screw where it seats into the loader.
Nothing worse than a loader that wont come out.

The 5/16" I understand, but how long again?
Also, I checked around and it looks like black oxide is only a finish? From ARP it looks like only the stainless steel is black oxide coated? Thanks!
