correct angle for a drive shaft with 2 joints

[gn7]

He has said before that his strut is a 10* and his Vdrive is a 12*. If he changes to a 7 or 8* strut, that would put his Rewarders pointed almost up at the sky unless he changed Vdrives too.

It always amazes me when someone gets a boat to work and then they take it apart and don't record where everything was at before hand. Hopefully, he measured the angles of the prop shaft and driveshaft before he took it all apart. It is possible that his 10* strut was sitting at 9 or maybe 8.5* depending on how they had it sitting. In one of his other posts he said he had this one taking a good set finally. If so, that is where he should put everything back, unless he is planning on buying some new hardware (strut, v-drive, engine plates, possibly a shaft log).

Unless its a drop thru strut, I doubt the angle was changed much from what it is simply bolted to the hull. Even with a drop thru, If he reinstalls it with the same holes drilled in the strut and mounting angles, its not going to change much.
If he put the strut back in the same place, All the angle figuring is done. Now its just a matter of putting the boat back together.

I agree as long as they didn't do any filling on the bottom of the boat where the strut was located. I know on the Guasti, it had a 9* bronze strut. The bottom of the boat was ground down and when the strut was bolted to it, it sat at 8.25*. When I put the steel strut on it, I intend to have it sit at the same angle with the back of the barrel in the same location. The boat was rigged as a SBC boat before so I'll start back with what worked all those years ago. And before anything got filled, sanded, or touched, every piece of hardware was bolted back into the boat to make sure where it was originally located and at what angles.

no work on the bottom other than a little cosmetic..
