The really "Old School" boating thread

[gn7]

V or a double V or is it an M, I just don't know. The person that owns it called it a V-drive so I went with it.

It belongs in this boat, '55 twin screw Mandella.

I only called it that because that's what they call them on the TFHs today.
If that's a 55 Mandella, they are more similar to a Rayson that I thought they were when Joe died. The entry on that thing is a dead ringer for an early Rayson.

Guessing....output shaft of engine is the third leg of a triangle and drives a chain from above to the two outer inputs of the box then each inner shaft is driving a prop shaft? They seem pretty close for that to work. How else?

Dave Sammons' work bench?

I have no clue Carl. That's not how they work or look today. That setup would have the props turning the same direction. Not sure how it works, but the chain setup is very interesting. My guess is, its 1 to 1 ratio.

Today its one input direct to a output, plus one idler to an output, making the outputs turn in opposite directions.
