Does anyone have a spec sheet for a 1950's Gray Marine Vee Drive, Model 113, Number 1294?
I need to know the max HP and RPM.
Thanks

Chris , like yourself I am seeking information about these Vee Drive Boxes .I have two , a left and a right hand unit .However they both have the output running the same way,counterclockwise.They are model 7:4 691 and 692.Theshafts are are horizontally offset.There is a number cast into the top of the actual gearbox casting , Timken5200W127 , probably the bearing numbers ??

Chris, From a catalog cut on the '30-'32 year gray motors. The V-drives were rated at 50-150 HP at 3000 RPM OR any engine developing a torque not greater than that of 200hp at 3000 RPM. Look for a period special catalog #51-B according to the catalog. Not what you're looking for but relavant.

Re the output shafts having the same rotation.
It is quite common to have one of the engines
running counter clockwise in a twin engine set up
so you would not have both props spinning in the same direction ,(the steering and handling would
be diabolical otherwise)Mercruiser do it alot
