Seafari Pre-Alpha gear ratio
The decal with the gear ratio stamp on my 1971 Type I (aka pre-Alpha, aka Type R) outdrive is missing. Anyone know the gear ratio on the 1969-1973 Mercruiser 140 equipped Seafari's with the older outdrive?
I've been offered a free rebuilt 1974 early Alpha 1 drive (short splined-shaft) with a 1.65 gear ratio that one of my West Marine customers has had sitting in his garage for over 20 years, and I think the ratio on my current outdrive is either 1.81 or 1.95. It makes a difference in figuring out which prop to work with. This guy had the drive rebuilt and it was in his truck when his barn caught fire and burned the boat with it. Insurance was had.
