I'm glad you were off on the weight!

Since you prefer the pusher configuration, with the prop toward the rear of the boat, I would go with an OS46AX. You can't go wrong with those motors. Plus they put out a bit more HP than the Super Tiger, plus the OS is within your price range at $104. The extra HP hill help the engine not have to work as hard. When running a pusher configuration, they will run warmer than in a puller configuration. The less the motor has to work in a pusher configuration, the better for the engine life.

With the OS46 you can run up to an 11" prop. So with either stand, you'll be fine. I also would like to see the other stand when you can get the pic up.

Keep us posted.
