Yes I found the inner transom plate. It was at my shop under the fixture table. I actually just saw it the day before you wrote this. Its not worth taking everything apart to put it on.

0-60' foot in one second not 0-60 MPH in one second.

They can really turn 6200 rpm for more then a few seconds. There are guys doing the tractor pulls that are running that high for 30 seconds at a time. It would take me less then 30 seconds to run the shootout at LOTO so we will turn them up next year and see what it will do. I would imagine the drives will not make the end of the shootout course.

Bell housing's completed....
. Almost...
we had another problem / made it better thing happen. The drill for the 7/16" tapped holes for the transmission to mount to the back plate were drilled wrong size? I checked the drill bit before and after it was drilled and it was right but the hole was big enough that there was hardly any threads left on the sides of the hole. I checked the drill chuck and it was bent. (I probably used it in my hand mill with an end mill or something) So we had originally planned on drilling them bigger for a steel insert fitting so the transmission bolts would be into steel with bigger threads in the aluminum (which is a lot stronger) but then had decided not to but now we had to.

Bell housing:
Another change: when we were designing the back cover at first it followed the shape of the bell housing but I thought it did not look good so we went ahead and made it round. Then after finishing it and putting it on the bell housing I decided to re-machine it and follow the outside shape.

Mine do not smoke at all when running, just a little puff when you first throttle it. Most of the people that race them make more power the easiest way which is just throw a bunch of fuel at it and it will go. On mine it cannot smoke or we will not have the fuel mileage we need.

Did you ever think to use the drive guardian to protect the outdrive?

The drive guardian is a clutch. It does not change the torque of the engine or output ect. it just slips when it gets a spike. You set it for a certain percentage of power more then you can make (we used to set ours at about 50% more) then when you come out of the water and the engine speeds up when the prop bites the water the clutch will slip a few revolutions till the engine is brought back down to the props speed. But it is only made to slip for a second. And they generate tremendous amount of heat in a second or two. So technically you could set it for 1200 ftlbs and the engine making 2000 ftlbs will continuously slip the clutch. After probably 20-30 seconds it will be glowing red and will either come apart and send shrapnel through the boat and it will sink, or it will generate so much heat that it will catch the boat on fire.

Regardless. I think the point is that the spikes could be much higher than the 2kftlb you're engine can make so you would still be saving the drives from those spikes. So you would set it above or at the engines max torque output despite that being above the drives rating.
