Working on this boat …. very long story and I don’t want to taint anyone’s thoughts before they answer by going into it.
It has 2 motors that go to one V drive then to one prop. One motor sits in front of the V drive and one in back of it. Both motors have transmissions and don’t worry about motor rotation or anything else but the question. So here goes.
How would you connect the two motors to the V drive?

A,


B,

Hmm, set up one engine for reverse rotation then adapt a transfer case to take power from both engines down angle to the prop shaft?

Call PAT WEISSMANN !!!!!!!

pic A would be the way it would be done but i have never heard of it

Pic A. Do you have the original V-drive? I assume that you don't. Depending on the drive you use, you would need to rig a straight thru shaft on the top. Basically just add another flange on the opposite side of the case. (easier said than done) The transmissions should allow you to engage / disengage each engine separately, so I think it could be a solid coupling.

Are you going to use crash boxes or standard trannys? How would regular transmissions react to differences in RPM? I would think trying to sync both engines through a borg or similar could create a lot of heat. Crash boxes would effectively lock both engines together when in gear.

I know your boat has a very unique setup, and I can only imagine trying to dock a single with two crash boxes to deal with!

Does any of this make sense???

start over (one engine two props) and two trannys

pic A is the only way it will work if there is any over drive in the v drive

Have the original Casale 1000 (only about 40 made), 1.09 to 1. A B/W Velvet drive, 1 to 1 on each motor.
As I said I don't want to get into all the logistics until I get a consensus on how folks would do it if it was theirs. I will be more then very happy to discuss it all then.

What boat is this in? I would realy like to see some pics.

I like the odd ball projects.

nice project , have you called casale and talked to them , i used to talk to Andy out there but it has been years and he was older so i am not sure if he is still around.
