Nice Project Pat,
How much power can the drives handle ?
Thanks

Now I gotta think. Hurts......:ack2:
Does engine torque go opposite of rotation under acceleration?
Sorry my bad I meant RH... I always get that backwards because I am Left Handed.:willy_nilly:
The torque leans the boat to the right under accelleration so the impact of the blade to the water counters the action making it somewhat balanced.
We designed the drives to take big power as well as being very efficient. It will run very well with light power. The lead shaft is 110mm in diameter. the rear shaft is the same as a #6....see photo.
kind of gives you an idea we are not playing around.

Blackhawk ?????????? mmmmmmhhhh
I like you aerotek the way it is. Why do you have the water pick up on the right side? How is your slip #? Find one of my dry-sump #4 drives in the UAE. We did 10 of them. Contact victory team.
I was thinking of a 46 ft full canopy single drive center rudder raceboat.:26: something that can run some real mph.
The steering is 40 deg total 20 left 20 rt. Docking is always better with a DP drive.
Throttle Up is making all my props from now on. I have had great results with them so far.
I did not look at the blackhawk props when I started this design. I wanted to be able to use the bravo type props with the internals knocked ut and splined so people like Throttle Up could use the tooling for the castings they already have thus cutting cost. That is why we went with the 26 spline on the rear for the hp version. We can also run the bravo type 19 spline for the economic version of the drive.
The way I looked at it is:
single prop bravo smallblock baseline package
then dual prop up to 1000hp with bravo type thickness props
single high performance
dual prop high performance. with HP thickness props
stern drive
fixed trimmable no skeg with a center rudder.
Lots of combinations:reddevil:

The water pick up is making a mess out of the water going to the prop. I would get it over to the center so it will get the bullet.. It is worth a try.
I will see if they have any more #4's.

Make the pickup horseshoe shaped so it clears the drain plugs. Water does not like 90 deg changes in direction. The pick up you are running causes lift and lots of drag and aeration to the water that gets in.

Horseshoe come out parallel with the bottom and loop back in clearing the drain plugs.
Here is a quick sketch.
