This may be doable after all....
Digging through my parts, I found another bracket. I removed the pointy (non-gen) bracket and mounted a non-pointy bracket w/ gen. Things are tight, but it's "all there".
I never really noticed before, but the "point" (seen here on the starter side) is offset to the side & slightly forward of the casting "face" on a non-pointy bracket...
I thought I could maybe just drill a hole and mount some sort of point, but that won't work, because of the offset mentioned above, and because of the way that would interfere with the bolt that connects to the intake. I'll have to have something welded as Gary mentioned, so I'll have to engineer something really carefully & find an expert welder. Welding aluminum takes talent......but welding an aluminum casting
is a whole 'nuther level of difficulty.
The other consideration in all of this is the regulator. As you can see, my rebuild of this engine was done without the transom-mounted control box; my solenoid is under the cowl, and all of my controls are run out to a modern Deutsch connector. (This connects to a cable that runs to my boat's dashboard. It can also connect to a stand-alone switchbox that I use for bucket testing).
So with that said, I'm looking to source a small electronic regulator (like the JP Cycles 381-309), but it needs to be small, as the space is getting tight!
So progress is being made....but I'm not "there" yet! But with respect to space, I could gain a bit were it not for the huge air intake! Later-model engines didn't have this monster, instead just had that little plastic "grate" over the carb intake. Would there be any downside to jettisoning the air intake?
