They said it ran 103 with the pro chargers. I bought the engines off them in last month. Took all the procharger stumm and I am building a pair of 383s with components.

Is that hull and drives for sale?

Hull was for sale in classifieds here on oso

Sounds like you guys have some great projects going on! Years ago I did some testing with the hawk on several different boats. One was a 24 fountain cs. We gained 8 mph on it just by installing a blackhawk on it. I'm in the process of building a hallett vector with an its and a blackhawk. I have two setups for the hawk. One is a # 3 shaft and one is the stock counter rotating configuration. Hopefully I will have it finished this summer. I'm also considering having a custom # 6 style propshaft made which will allow more prop selection

8mph and that roost? This has my attention.

That 20' Cigarette sounds great from you described, please post some picture of the boat, motor, and drive, that is one very boat you have with the power and drive, to me it is very desirable and very f*cking cool!

Pretty sure this is that 20 cig http://www.lipship.com/posts/view/19

Probably the best video to see a blackhawk in action, that was posted in the past https://www.youtube.com/watch?v=VbSZ7BM2rEE

Bob leach used to put them on his 22 Daytonas with 502's in them. They ran just under 100 bone stock. He did a lot if testing for mercury with them. It was his idea of having a 2 speed trans that prompted mercury to design and build the black trac transmission. The only downfall of the blackhawk on the Daytonas was getting on plane. The 2 speed black trac transmission was mercury's answer. The problem with that was space. With the correct setup these drives are amazing

Yes that is my 20 and I did the video as well. The red 750 boat is a friend of mine.
