I have machined my marine front cover to direct mount a PG 150 hilborn pump. the problem i have is how to drive the pump. It uses a 3/8 hex driveshaft. In a perfect world the cam would come LH 1/2 - 13 thread and i would run down to Lowes and pick up a socket head bolt. Real world cam is RH 7/16 -14 and the best price LH bolts i can find is $75 for a box of 10.

The 2 options i have thought of is

1: Order bolts, redrill and tap cam to LH 1/2-13

2: Use RH 7/16 socket head bolt. Then after cam endplay is set and bolt torqued. drill and tap cam snout for a set screw.



Wonder if anyone out there has any other ideas (or opinions on these)
