Anyone know if a Black Hawk Drive is stronger or weaker than an Alpha 1 Gen 2 ? Is it faster... Slower ... Planes better or worse... Why did they quit making them...

apples to oranges. completely different style of drive and what you put them on is another huge variable,

The Blackhawk is a surfacing/semi surfacing counter rotating duo-prop drive. It shares quite a few internals with Bravo based drives and therefore is essentially as strong, or weak, if you prefer, as a Bravo. The biggest weak point was the case themselves and that is where there were quite a few failures. The main reason they stopped making them, was application based, as there were very few boats that were accommodating to the design/application. When they worked, they worked quite well, when they didnt, they didnt. Where they tended to work well was on boats size appropriate, with substantial natural rocker. Ultimately there was not enough of a market.

I have no idea what kind of boat you are thinking of swapping an Alpha to a Blackhawk, but it is probably pretty unlikely that it would yield positive results, unless you have one of the forementioned type hulls.

Cant think of one boat that worked well with a Blackhawk ,that was offered with a alpha .if there was ,someone here probably knows

The P-29 worked well with the Blackhawks.

Indeed they did, but the P-29 hull was intended to be application specific for the Blackhawk. Put them on standard 29 and its a different ballgame. The boat to look at for Alpha/Bravo and Blackhawk differences might be the Donzi "Blackhawk" and standard versions as I dont recall any substantial changes in the hull from one app to the other?

My 21ft superboat came with a blackhawk outdrive from the factory. It now has a bravo 1 on it. The bravo sits way to deep. Eventually going to put a shorty on it.

Are Blackhawks a straight swap from a Bravo1? Ive heard the little beaks do very well with them.

Same helmet, if thats what you mean?
