Well, it appears that Gil Marine is out of business. Michigan Wheel (who responded, great Customer Service) said they were only the distributor of the prop, never the builder, looked but couldn't find any installation instructions.
I just took it down to my local expert at a dealership parts counter. Certified mechanic for 35+ years now, remembers the CVZ's when they were new, etc. He loves Goldie too...his first reaction...let me know when it throws a blade (laughed) then said a) you're not gonna be happy with it; b) that I'm supposed to take that spacer/thrust washer off for this prop. He's a wealth of knowledge...seen it all. Asked how much I paid...$39.00...said...yep, for that, its a perfect spare.
Just said to take the washer off, the hub is tapered to fit correctly (which it is), and bolt it on. So...I shall.
I'll play with it over the 4th when I'm up North...it'll give me something to mess around with.
