    Default velvet drive

    Has anyone heard of removing and replacing the pump reversed 180* to achieve a counter rotating output.

    Yes I have heard of this also, never did it though. Its been 14-15 years since ive been in a velvet drive, but i do remember being cautioned about the reassembly & orientation of the pump or it will work backwards, foward would be reverse ect. If memory is correct, i remember marking pump to case before tear down, i think by turning pump 180 youd get reverse rotation, key word,think, like i said its been a long time since ive even looked at one. Im sure spmepne with more exp. will set us both straight. Good luck ! Phil

    A Velvet Drive can be used on either a standard or reverse rotation engine by changing the orientation of the front plate. Changing the plate orientation configures the pump so that it will work in the rotation that matches your engine. If you have the plate in the reverse rotation position for a standard rotation engine, the pump won't work and the transmission won't engage. (and vise/verse)

    Changing the orientation of the front plate will not by itself change the rotation of the transmission output.

    Scroll down the forums to the "Manufacturers Zone" and re-post your question in BAM Marine. They should know the answer to your question

    Here's a direct link: BAM Marine

    X2. If you use reverse to change rotation of the motor (go from reverse rotation to standard rotation engine), it will burn up the reverse clutches. If its a V drive velvet drive, you can switch from a belt drive to a gear drive.

    Yes you can rotate the front pump 180
    I did it to my velvet drive
    when I went from a counter clockwise to clockwise rotation engine
    If you ain't the lead dog the view is always the same !
