The thread on all.the motors you mention is 3/8-16 UNC.

If you can machine something…..great!

If you can’t, here’s a 3/8-16UNC to 1/4"NPT adaptor. Part # 33T

3/8-16 is a bolt thread, not really a "fitting" thread. But once you convert to the "world of NPT", there’s nothing you can’t do….

NJ-Boatbuilders contributed this on a previous inquiry . . . 😀
You will have to copy the Stevens Instrument site to see the fitting.

I used the fitting from a lower unit fill kit…

FYI: I found an adapter online several years ago that adapts these pumps to the metric size used on most of the newer Imported motors. This adapter can also adapt whatever you use for pressure testing.
