    B7100D HST transmission power transfer

    Thank you. I also wanted to point out that I would like to reuse the hst for the reverse capability. Something I won't have with a motor hooked up to a chain... Also, I am not going to keep the 90* gearbox currently on the boat. Thanks for the insight!

    Yes! Except this project sat for who knows how long, so the electric motor was shot (magnets were literally flaking away). Plus, the gearbox on the boat was only rated for .7hp and a 1:1 ratio. So plan b was... I had this old Rusty tractor sitting in the yard... Plan c is a nice lawnmower...

    B7100D HST transmission power transfer

    Thanks for the info gents. The paddlewheeler is actually an 18 ft pontoon with a paddlewheel that was set up with an electric motor that I picked up at an estate sale. The paddle itself is chain drive so I am planning on using a 90* gearbox (or worm drive) off of the hst with a proper...

    B7100D HST transmission power transfer

    Hi all, I am working on a project paddlewheeler boat that is using a salvaged B7100 for power. Right now I am confused as to the reverse functionality of the hst. I would LIKE to utilise the motor and HST to power the paddlewheeler. I don't want the heavy gearbox or axle. I assume that this...
