Bravo I or II?

[Someday Lady II]

I am in the process of acquiring a 1991 350 Sundancer with Bravo outdrives. The decal on the housing indicates that it is a Bravo I while the owner insists that it is a Bravo II. I was told that the part number of the installed props is 18616-40-21P and in my book that would make it a II. I would prefer the II but it is not a deal breaker either way.
Does anyone have any advice on what else to check?

I think you will need the drive serial number to be sure.

The prop on a bravo II is massive. Mine is 18 3/4 inches across. The only difference in Bravos is the lower part of the drive (and props). I bet you have bravo I's which is fine for your set up. Bravo IIs are usually used in a single configuration for 30' or so cruisers.
Here is a pic of an Alpha prop (similar in size to a Bravo I prop) next to my Bravo II.

Thanks all for the comments.
Here is a picture of the drives and maybe that will help.

... look like Bravo 2's to me.

Yep... looks like II's... look at the difference at the end above the cavitation plates, the Bravo I has a sharp cutoff where yours has the tail sticking out beyond the prop.

Hope this helps...

Bravo One Sterndrive Unit serial# B664190 and Above
Bravo Two Sterndrive Unit serial# B892613 and Above

From Mercruiser website:

Bravo 1: With a focus on high speed performance, the Bravo 1 sterndrive is used for single, twin or triple engine applications and can produce speed up over 100 mph for gas engines up to 600 HP. In addition to triple-digit speeds, the exclusive performance torpedo design and dual water pickups allow the Bravo 1 to handle high and low speeds well.
Bravo 2: The Bravo 2 sterndrive is designed for twin engine applications and can power a boat up to 55 mph for gas engines up to 450 HP. With a wide gear case, the Bravo 2 is able to accommodate a propeller up to 20” in diameter that propels a boat on plane faster and improves fuel economy.

Bravo II prop shaft diameter is much larger than a Bravo I. I think that Bravo II decal sets are harder to find than Bravo I. Its possible the drives were repainted and re-decalled using Bravo I decals.

Thanks to all who replied.
The deal has been done and I am now the second owner of a 1991 350 Sundancer with twin Bravo II outdrives ( yes, they are B2's apparently a special order when the boat was purchased new ).
1983 270 Sundancer with tri-axle 5th wheel trailer will be going up for sale as soon as winter is done.
Up here that could be another 6 month.
