You need to find an old outdrive and bolt it to the wall. Oh, and have external hydraulic steering for good measure. That picture is awesome.

Dang it...

The Video outside was taken with my old Camcorder.. Don't have those on the PC....
Found the Video from inside. ... just noticed, this was 7 years ago...

An old thread for sure but I finally removed the silent thunder box this year and installed these tips. They make the motors sound so much better without being obnoxious! The best part is I gained 3-400 rpm on the big end and 3-4 mph. I know this sounds impossible but i believe the mph difference is due to weight and the way the boat is balanced in the water. Gps doesn't lie.
