The really "Old School" boating thread

Old school V-Drive.

Old school V-Drive.

Looks more like a "W" drive for dual counter rotating props.
I didn't know that Marbet made stuff like that.

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.

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 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.

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.

Hey Bob or others, would you be kind enough to post up a good photo of a conventional Casale V-drive box on the bench AND installed IF you have some good pics? Something showing the IN and OUT??? Pretty please??? OR maybe even an OLD HallCraft box / toploader / water cooled???

Some of the audience may not be familiar with the simplicity and ruggedNESS OR the quick change of gears in the V-drive install/design...

I'll try to find a better pic of the Mandella.

Pic of inside the drive.

That's about what I expected to see once you showed the input/output side.


Nothing says both inputs had to hook to the engine. Hook one input to the engine, the other acts an idler, you could use the shaft to drive something if wanted.

Coupling outputs to prop shafts with chains and sprockets was common as dirt in those days. Still is used in hydros and some crackers.

Here you go Bob.

I don't remember there being that much gull in the entry from the keel to the chine line of the Mandella's. Doesn't seem that Harlan's new "1958" boat has that gull and is flatter from the keel to the chine.

This thing has a definite gull in the entry. You can see the curve in the bottom even at these angles. Its one of the dead give aways of an early Rayson.



FIRST PLYWOOD v DRIVE MANDELLA


FIRST RAYSON HULL



Basically the same Rayson hull. The gull is much easier to see.




Love to know how the 2nd input was used, if it was. Only one U joint hanging from a input here, and the other doesn't look like it ever had anything hooked to it.
